Resumen

Animal-assisted therapy has positive effects on cognitive function, depression, performance ability, and social functioning in elderly patients. The aim of this study was to evaluate the effects of rearing pet insects on the cognitive function of healthy elderly participants, with fMRI (functional magnetic resonance imaging) being used for this purpose. Community-dwelling right-handed elderly women (≥60 years) with normal cognitive function were enrolled and randomized at a 1:1 ratio into two groups: insect-rearing and control (n = 16) groups, with the insect-rearing group being further classified into two groups for analysis according to the subjects’ scores in the Wisconsin Card Sorting Test, WCST) at the baseline fMRI: Insect-rearing group I with a relatively high score (n = 13), and insect-rearing group II with a relatively low score (n = 6). The insect-rearing groups received and reared crickets as pet insects for 8 weeks. The WCST consisted of two variations, a high level baseline (HLB) and semi-WCST version. There was a significant difference accuracy of the HLB–semi-WCST (p < 0.05) in insect-rearing group II after 8 weeks from the baseline test. In the fMRI analysis involving the WCST reaction test, increased activation was observed in the right dorsal lateral prefrontal cortex and parietal cortex in insect-rearing group II when the semi-WCST, rather than the HLB, was performed. Rearing pet insects showed positive effects on executive functions and performance improvement in elderly women. Further larger studies on the effects of pet insects on cognitive function are warranted.

Resumen

Rearing insects for pest experiment it’s very critical. The condition of rearing such insects impacted the smooth running of research. This condition also happens in the rearing of Asian Citrus Psyllid (ACP), Diaphorina citri. ACP is one of the most dangerous pests of citrus since responsible for the huanglongbing disease vector in citrus. Many researchers, either laboratory or field-based use a D.citri for object experiments. A clear and recent description of the types of insects or arthropods that disturb the rearing ACP is needed, especially in Indonesia. The research was conducted in the greenhouse of Faculty of Agriculture, Gadjah Mada University, from January 2021 to September 2022. The rearing of ACP uses orange jasmine (Muraya paniculata) and citrus (Citrus nobilis). The collected insect and spider preserved in alcohol or pined in insect tray and identify them based on related literature. This study proposed to assess the nuisance insect that infested on rearing of D.citri based on greenhouse conditions. Our results showing that the many nuisance insects that disturb the growth of rearing in D.citri. A total of nine insect and spider attacking D citri, they are black ants (Dolichoderus sp), aphid (Aphis sp), leaf roller caterpillar (Phyllocnistis citrella), cockroach (Blattella sp), ladybug (Exochomus nigromaculatus), mite (Tetranychus sp), Mealy bug (Pseudoccocus sp), Scale insect (Aonidella aurantia) and Spider. Those nuisance insects and spiders attack D.citri colonies in different ways and stages. The attacking nuisance insect affected to affected the size of the ACP culture.

Resumen

As wild harvesting of insects gives way to mass rearing, there is an urgent need to develop expertise and methods in insect animal husbandry and facility design. In order to advance the science of animal husbandry and production in this field, comparisons and contrasts of different insect rearing facilities currently in production are likely to be beneficial. Here we initiate this discussion by suggesting a focus on insect rearing facilities at the two ends of the production scale spectrum (small-scale rearing and mass rearing) that have different end products (insects-as-food and insects for other purposes). We suggest that organisations with a philosophy of information sharing (e.g. universities) need to play an active role in this developing production system, by bridging gaps between academia, industry and traditional knowledge to ensure a rapid and societally acceptable development of wide-scale entomophagy.

Resumen

Artificial diet for insect rearing is necessary at the time a lot of insects required periodically and continuously such as for pesticide efficacy research, biodiversity conservation, and for the activity of fruit fly management with the sterile male technique for instance where it needs millions fruit flies weekly to be sterilized and then subsequently released. Insect artificial diet will also increase the efficiency of time, energy and fund in the procurement of insects compared to insect rearing with its natural diet. Various artificial diet classifications and its compositions have been developed so far in varying degrees of rearing success.

Resumen

Mass insect rearing can have a range of applications, for example in biological control of pests. The competitive fitness of released insects is extremely important in a number of applications. Here, we investigated how to improve the fitness of a transgenic diamondback moth, which has shown variation in mating ability when reared in different insectaries. Specifically we tested whether infection with a gut bacteria, Enterobacter cloacae, and aseptic rearing of larvae could improve insect growth and male performance. All larvae were readily infected with E. cloacae. Under aseptic rearing, pupal weights were reduced and there was a marginal reduction in larval survival. However, aseptic rearing substantially improved the fitness of transgenic males. In addition, under aseptic rearing, inoculation with E. cloacae increased pupal weights and male fitness, increasing the proportion of transgenic progeny from 20% to 30% relative to uninfected insects. Aseptic conditions may improve the fitness of transgenic males by excluding microbial contaminants, while symbiont inoculation could further improve fitness by providing additional protection against infection, or by normalizing insect physiology. The simple innovation of incorporating antibiotic into diet, and inoculating insects with symbiotic bacteria that are resistant to that antibiotic, could provide a readily transferable tool for other insect rearing systems.

Resumen

Environmental pollution, population increase, water availability and misuse of land are inexorably driving humans to take on important challenges related to sustainability. The next future is expected to see a significant increase of food and feed demands, which determines a serious threat to well-being levels and even survival of modern societies. Within this scenario, the efficient and sustainable use of insects as protein sources has been invoked as a possible strategic solution. As a candidate for remarkable growth, insect farming promises significant benefits to agri-food industry, offering interesting opportunities for implementing circular economy. In the present work, we review selected literature on insect rearing with the aim of providing a short rigorous introduction to the field to researchers, entrepreneurs and common readers. After a general overview of the field, including a description of insect nutritional values, the review focuses on the three insect species that are seemingly set to beneficially affect aquaculture, which is the activity presently more sensitive to circularity and sustainability innovation. Once traditional and advanced insect rearing methods are described, the challenges that the field is going to tackle are suitably highlighted.

Resumen

Edible insects are expected to become an important nutrient source for animals and humans in the Western world in the near future. Only a few studies on viruses in edible insects with potential for industrial rearing have been published and concern only some edible insect species. Viral pathogens that can infect insects could be non-pathogenic, or pathogenic to the insects themselves, or to humans and animals. The objective of this systematic review is to provide an overview of the viruses detected in edible insects currently considered for use in food and/or feed in the European Union or appropriate for mass rearing, and to collect information on clinical symptoms in insects and on the vector role of insects themselves. Many different virus species have been detected in edible insect species showing promise for mass production systems. These viruses could be a risk for mass insect rearing systems causing acute high mortality, a drastic decline in growth in juvenile stages and in the reproductive performance of adults. Furthermore, some viruses could pose a risk to human and animal health where insects are used for food and feed.

Resumen

Forensic entomology is the use of insect and others arthropods in solving crime. During this purpose, forensic entomologists use carrion insect communities to produce evidence in case of murder, suicide, neglect, accident or poaching, since they are natural witnesses of the crime scene. This offers of insects as physical evidence during legal procedures are use worldwide except in Africa where the documentation of this domain is poor. The present study was to compare the diversity of necrophagous insect gathered at the study site and that of the insect obtain from the rearing of thier larvae in the laboratory under natural environmental conditions. Adult flies were identified to species level. Overall, 3414 adult flies were obtained both from the census on the field and from the rearing in the laboratory. These flies belong to 3 classes of insects namely, Insect, Arachnida and Myriapoda with 3343, 70 and 1 individual respectively, distributed amongst 9 orders, 30 families, 20 genus and 27 species.

Resumen

The worldwide growing consumption of proteins to feed humans and animals has drawn a considerable amount of attention to insect rearing. Insects reared on organic wastes and used as feed for monogastric animals can reduce the environmental impact and increase the sustainability of meat/fish production. In this study, we designed an environmentally closed loop for food supply in which fruit and vegetable waste from markets became rearing substrate for Hermetia illucens (BSF— black soldier fly). A vegetable and fruit-based substrate was compared to a standard diet for Diptera in terms of larval growth, waste reduction index, and overall substrate degradation. Morphological analysis of insect organs was carried out to obtain indications about insect health. Processing steps such as drying and oil extraction from BSF were investigated. Nutritional and microbiological analyses confirmed the good quality of insects and meal. The meal was then used to produce fish feed and its suitability to this purpose was assessed using trout. Earthworms were grown on leftovers of BSF rearing in comparison to a standard substrate. Chemical analyses of vermicompost were performed. The present research demonstrates that insects can be used to reduce organic waste, increasing at the same time the sustainability of aquaculture and creating interesting by-products through the linked bio-system establishment.

Resumen

A rearing methodology for dogwood borer was developed, using standardized procedures at each developmental stage. These methods enabled the establishment of a laboratory colony and efficient production of synchronized cohorts of each of its lifestages throughout the year for specific experimental needs. The behavioral repertoire shown by mated female dogwood borer in an apple orchard was characterized and quantified and the diel periodicity with which those behaviors occurred was determined. Mated females were easily recognized, based on their characteristic casting flight directed toward areas below the graft union of apple trees, and were observed more frequently during the late afternoon and evening. Casting flight, probing with the ovipositor, and oviposition were the most frequent behaviors observed, but the duration of those behaviors was relatively short compared with the much lengthier periods of resting behavior that typically occurred within the canopy. Data from a previous, three-year study in two newly planted apple orchards were subjected to geostatistical analyses to examine the temporal and spatial patterns of infestation by larval dogwood borer and to gain further information about the spatial scales at which oviposition occurs. There were moderate to high degrees of aggregation of dogwood borer infestations on neighboring apple trees, with ranges of spatial dependence from 7.50â 19.87 m. No directionality was observed in the spatial autocorrelation of infestation and it appears that females utilized oviposition sites equally along and across orchard rows. The aggregated nature of infestations requires that random, independent samples must be taken from a number of sample pairs at distances greater than the range of spatial dependence to ensure that sample data are not autocorrelated. Alternatively, an efficient sampling program for mapping dogwood borer infestation can be achieved by limiting sample points to distances within the range of spatial dependence. These sample points can be used in interpolating algorithms, such as kriging, to predict infestation at unsampled locations in space for use in site-specific pest management programs. The external morphology of male and female dogwood borer antennae and their sensilla were examined using light and scanning electron microscopy to characterize, measure and compare the types, number, and distribution of sensilla. Although the general shape and size of male and female antennae were similar, those from females possessed a greater number of generally smaller antennal flagellomeres. The flagellum of both male and female antennae contained seven sensillum types including auricillica, basiconica, chaetica, coeloconica, squamiformia, styloconica, and three subtypes of sensilla trichoidea. With the exception of sensilla basiconica, which were present in roughly equal numbers on male and female antennae, all other sensillum types were significantly more abundant on female antennae. The antennae of female dogwood borer appear well equipped to perceive olfactory stimuli, based on the types and number of sensilla present. Coupled gas chromatography and electroantennogram detection (GC-EAD) analyses of headspace collections from damaged and undamaged tissues from apple and dogwood trees were conducted to examine and compare the antennal responsiveness of female dogwood borer to host plant volatiles. A total of 16 and 9 compounds from apple and dogwood tissues, respectively, consistently elicited an antennal response in females. There were no differences in the response of antennae from virgin and mated females, and the amplitude of the female response to host odors was greater than that of males. Six compounds were identified from the headspace collections from apple trees, four of which (octanal, nonanal, decanal, and methyl salicylate) were identified from all apple tissues sampled. A novel compound, Î±-bergamotene, was identified from injured apple bark, from apple burr knots infested with dogwood borer larvae and from larval dogwood borer frass, and appears to be produced by apple trees in response to injury. Another novel compound, methyl-2,4-decadienoate, was identified from infested burr knot tissue and appears to be produced in response to an insect-plant interaction. Two compounds, hexanoic and nonanoic acid, were identified from headspace collections from dogwood trees. Numerous approaches were used to examine the behavioral response of mated female dogwood borer to host plant headspace collections and to individual compounds from those collections that elicited a strong and repeatable antennal response. Under both natural and semi-natural conditions in the field and in laboratory bioassays, neither attraction/orientation or consistent oviposition were documented and it is apparent that correlating the electrophysiological and behavioral responses of mated female dogwood borer to olfactory stimuli from their host plants will require further research on bioassay development.

ENGLISH ABSTRACT: The Mediterranean fruit fly (Medfly), Ceratitis capitata (Wiedemann) (Diptera: Tephritidae) is well-known as a destructive pest of fruit worldwide. Various control methods have been used against this insect. The sterile insect technique (SIT) is used as an important and successful technological method for controlling or eradicating this pest in many countries. A key factor to successfully apply SIT is dependent on the availability of efficient and economical rearing methods. Artificial insect diets with low cost bulking agents have been of interest to many researchers. The present study investigated the use of locally available maize meal as a bulking agent in such diets. Maize meal is used for human consumption (in South Africa) and contains small amounts of protein. This makes the reduction of imported torula yeast as an ingredient of the diet and source of protein possible, thereby reducing the cost of the diet. The larval development of the Medfly reared on artificial diets was studied in small and large-scale tests. The effect of the diets on larval production was evaluated using pupal recovery, pupal weight, flight ability, sex ratio, fecundity and egg fertility. The results of the small-scale tests showed that the diet containing maize meal could be used to produce Medfly more economically than the standard Krige diet used by the ARC Infruitec-Nietvoorbij Research Institute at Stellenbosch. However, in large-scale tests the ingredients quantities of the diets used were not the same as those of small scale-tests. The cost of the modified larval diet was not reduced in large-scale tests. This was ascribed to the number of eggs used in the tests to produce one million of fruit flies. The maize meal with reduced number of eggs require more diet to produce one million flies therefore, making it more expensive and less viable. When similar amounts of eggs were used, the diet appears to be a suitable alternative as the result obtained was almost similar to those of the Krige diet.
AFRIKAANSE OPSOMMING: Die Mediterreens vrugtevlieg ("Medfly"), Ceratitis capitata (Wiedemann) (Diptera: Tephritidae) is wêreldwyd 'n skadelike plaag. Die steriele insek tegniek (SIT) het in baie lande 'n belangrike en suksesvolle manier geword om die plaag te beheer en uit te roei. Die belangrikste voorvereiste vir die suksesvolle toepassing van SIT is die beskikbaarheid van doeltreffende en ekonomiese teelmetodes. Meeste navorsers is geïntereseerd in kunsmatige diëte met 'n goedkoop vulstof. Hierdie studie is ontwerp om die gebruik van plaaslik beskikbare mieliemeel as vulstof te ondersoek. In Suid-Afrika word dit vir menslike gebruik aangewend en bevat klein hoeveelhede proteïene wat 'n vermindering van die ingevoerde torula gis moontlik kan maak, en sodoende die koste van die dieët kan verminder. Die ontwikkeling van Medfly larwes op kunsmatige diëte is bestudeer In kleinskaalse en grootskaalse eksperimente. Die invloed van die diëte op larwale produksie is evalueer deur gebruik te maak van van papie-ontwikkeling, papie-gewig, vliegvermoë, geslagsverhouding, volwasse voortplantingsvermoë en eiervrugbaarheid. Die resultate van die kleinskaalse toetse het aangetoon dat die mieliemeel dieët gebruik kan word om Medfly meer ekonomies as met die standaard Krige dieët, wat in die ARC Infruitec-Nietvoorbij navorsings instituut by Stellenbosch gebruik word, te teel. By die grootskaalse toetse was die koste nie laer nie. Dit word toegeskryf aan die aantal eiers wat gebruik is om 'n miljoen vlieë te produseer. Die mieliemeel dieët met 'n verminderde aantal eiers benodig meer dieët om 'n miljoen vlieë te produseer, wat dit duurder en minder lewensvatbaar maak. Wanneer soortgelyke hoeveelhede eiers gebruik was, het dit geblyk dat die dieët 'n opsie is, want die resultaat was soortgelyk aan dié van die Krige dieët.

Resumen

The conversion of natural forests to production land uses has led to huge losses of biodiversity and continues to threaten remaining terrestrial flora and fauna throughout the world. The global demand for wood products and energy, which was partly responsible for the loss of primary native habitat, is now one of the leading drivers of afforestation with significant new areas of plantation replacing former agricultural lands. While plantations do not support the same biodiversity values as natural forests they do provide significant habitat for a range of species. Saproxylic invertebrates (species that are dependent on deadwood) are strongly affected by the temporal and spatial availability of different deadwood resources. Previous research on saproxylic invertebrates has largely been restricted to natural or managed natural forests predominantly in the Northern Hemisphere, where forest management practices have been modified to conserve these species This thesis fills a distinct research gap in New Zealand and is the first large scale study to quantify the effects of deadwood age, wood species, and landscape composition on saproxylic invertebrates in our plantation forests by direct rearing. In this thesis I show that thinning residues, which are currently retained in many plantation forests, provide significant habitat for a range of native invertebrate taxonomic groups, including diverse assemblages of Coleoptera and Hymenoptera. Deadwood age is an important attribute determining taxonomic richness of saproxylic invertebrates. Richness of invertebrate orders/classes and Coleoptera species all increased in older deadwood material, and a stepwise multidimensional analysis procedure indicated that the age of deadwood was the most important factor structuring saproxylic invertebrate community composition in Pinus radiata thinning residues. Deadwood age was a stronger predictor of community composition in thinning residue than measures of landscape composition, such as the proportion of remnant native forest cover. The change in saproxylic invertebrate composition that occurs with deadwood age was related to changes in the feeding guilds, with a transition from primary wood feeding species to predators/parasitoids and fungal feeders with increasing dead wood age. Because thinning’s are carried out at prescribed times throughout the stand rotation, stand age could be adopted as a proxy for deadwood age in these systems allowing forest managers a simple method for monitoring saproxylic beetle habitat availability . My research provides strong empirical evidence that supports the existing conservation paradigm that forest managers should seek to create a mosaic of habitats at the landscape scale to enhance biodiversity opportunities in plantations. In addition to the habitat opportunities provided by P. radiata deadwood that is derived from silvicultural practices there are several sources of native wood in plantations. Native woody resources are found in either the embedded remnant areas of native forest or in the understory of stands as many native woody species colonise this habitat. As yet the importance of native understory deadwood resources for saproxylic species is unknown. In addition it is unclear how the importance of such understory resources is influenced by proximity to remnant native forest patches. I used experimental wood billets of four tree species (3 native and the exotic P. radiata) placed along replicated transects spanning native habitat and adjacent early stage regenerating plantation stands to assess the saproxylic invertebrate assemblages associated with different deadwood species as a function of proximity to native forest. I found that an interaction between wood host specificity (local scale) and proximity to interior native forest (landscape scale) was the most important factor regulating saproxylic invertebrate community structure. Deadwood of the native subcanopy trees Schefflera digitata, Melicytus ramiflorus, Aristotelia serrata and the exotic conifer P. radiata provided habitat for different subsets of the saproxylic fauna. The most pronounced differences in saproxylic community structure were between the native sub-canopy broadleaf species and the exotic P. radiata. Surprisingly the P. radiata supported a greater species richness and abundance of saproxylic Coleoptera in native remnants than the native wood species in the same habitat. In general, species richness was higher in native forest habitats and declined with increasing distance from native habitat. These results suggest that both the diversity of deadwood resources that are available and their proximity to native remnants are important for maintaining saproxylic communities in plantations. However, two of the native wood species (M. ramiflorus and A. serrata) exhibited steep declines in species richness at the plantation native forest boundary, suggesting that the contrasting stand types (native remnant and young regenerating plantation stands) with their different microclimate may have had a significant influence. Future research needs to compare the saproxylic fauna of dead wood in mature plantation stands with adjacent native remnants to ascertain if the effect of native habitat proximity is due to landscape composition or a reflection of microclimatic differences. The large diversity of saproxylic species observed during this study highlights the importance of plantations as habitat for saproxylic species, particularly in heavily fragmented landscapes that retain little original native forest. My research findings provide forest managers with options for improving forest management to enhance opportunities for the conservation of saproxylic invertebrates. In addition my thesis provides one of the most comprehensive multi-taxon data sets of saproxylic species associated with a variety of deadwood resources. This information will be invaluable to future researchers that continue to work on New Zealand’s saproxylic fauna.

Resumen

Thesis (PhD (Conservation Ecology and Entomology))--University of Stellenbosch, 2011.
ENGLISH ABSTRACT: Codling moth, Cydia pomonella, is a worldwide pest and of major economic importance to the South African pome fruit industry. Sterile insect release is applied as a component of area-wide integrated pest management and includes the mass-rearing, sterilization and the release of the sterile insects. For sterile insect release, the improvements of rearing methods in terms of the quality of the diet ingredients and the economical aspect of the rearing method are examined. The effect of genetically modified maize meal, containing the Bacillus thuringiensis gene, in an artificial medium for codling moth rearing, is determined. The use of even a small amount of Bacillus thuringiensis resulted in larval mortality and prolonged development. These results are detrimental to a mass-rearing facility and must be considered by any rearing facility that uses genetically modified maize meal if the insect is sensitive to the gene. An alternative to maize meal in the artificial medium was tested and whole wheat flour was considered to be a suitable replacement. Agar agar is an expensive gelling agent used in the artificial medium. An alternative for agar agar (Kelcogel, Elastigel and carrageenen) is tested and the biological effect on codling moth is determined. Factors such as mortality, pupal and moth weight, longevity, fecundity and development time were used as quality parameters. Results showed that Elastigel was a suitable replacement for agar agar, with bigger pupae and moths, higher fecundity and increased longevity. The economical advantage of the replacement is a 40.91% reduction of the diet cost. The other gelling agents tested also gave acceptable results and can be considered if shortages of agar agar or Elastigel occur. A new method of mass-rearing codling moth larvae in a closed rearing system using large trays placed in a ventilated box is designed. This method is more cost and space effective as a smaller area is needed to rear a large number of moths. The risk of diet contamination is less because of the closed environment and more economical and effective air handling. This is the first report of its kind to describe the mass-rearing of codling moth in a closed environment and the risks involved in using genetically modified maize meal in an artificial diet for the codling moth. These results should be incorporated into existing mass-rearing facilities or taking into consideration when designing new mass-rearing facilities.

Die steriele insek tegniek word gebruik as ‘n komponent in area-wye geïntegreerde plaagbeheer en sluit in die massa-aanteel, sterilisering en vrylaat van steriele insekte. Vir die steriele insek tegniek is die verbetering van die massa-aanteel van die kodlingmot in terme van kwaliteit van die dieet en die ekonomiese aspek van die aanteel metode ondersoek. Die effek van genetiese gemanipuleerde mieliemeel wat die Bacillus thuringiensis geen bevat, in ‘n kunsmatige voedselmedium vir die aanteel van kodlingmot, is bepaal. Daar is gevind dat die gebruik van selfs ‘n klein persentasie Bacillus thuringiensis in die mieliemeel, mortaliteit en ‘n verlengde lewenssiklus in kodlingmot veroorsaak. Die gevolge is nadelig vir ‘n massa-aanteel fasiliteit en behoort in ag geneem te word vir enige insek wat op ‘n kunsmatige medium, wat mieliemeel bevat, geteel word, mits die insek sensitief is vir Bacillus thuringiensis. ‘n Alternatiewe bestanddeel vir mieliemeel, volkoringmeel, word aanbeveel. Agar agar is ‘n duur verdikkingsagent wat in kunsmatige mediums gebruik word. ‘n Alternatief vir agar agar (Kelcogel, Elastigel en carrageenen) is getoets en die biologiese effek op die kodlingmot is bepaal. Faktore soos mortaliteit, papie en mot gewig, langlewendheid, vrugbaarheid en lengte van lewenssiklus was gebruik as kwaliteit parameters. Resultate het getoon dat Elastigel ‘n geskikte plaasvevanger is van agar agar, met groter papies en motte, groter vrugbaarheid en langlewendheid. Die ekonomiese gevolg van die plaasvervanger, is ‘n vermindering van 40.91% van die dieetkoste. Die ander verdikkingagente wat is getoets is, het aanvaarbare resultate gelewer wat noodsaaklik is indien daar ‘n tekort van Elastigel of agar agar ontwikkel. ‘n Nuwe metode van massa-aanteel van kodlingmot larwes is bepaal. Die metode behels ‘n geslote sisteem, waar groter aanteel bakke in ‘n geslote, geventileerde boks geplaas word. Die metode is koste en spasie effektief en ‘n kleiner area word benodig om ‘n groter aantal motte te lewer. Die risiko van kontaminasie van die dieet word verminder as gevolg van die geslote sisteem wat gebruik word en meer ekonomiese en effektiewe lugversorging word gebruik. Hierdie is die eerste verslag van sy soort wat die massa-aanteel van kodlingmot in ‘n geslote sisteem beskryf en wat die risiko aandui van geneties gemanipuleerde mieliemeel in ‘n kunsmatige medium vir die kodlingmot. Hierdie resultate behoort in ag geneem te word vir reeds bestaande massa-aanteel fasiliteite of met die ontwerp van nuwe massa-aanteel fasiliteite.

Resumen

The effect of protein in adult and larval diets for Ophyra aenescens (Wiedemann) (Diptera: Muscidae ), a facultative predator of the house fly, Musca domestica L., was examined. A larval diet of coarse wheat bran, vermiculite and dried meat powder was found adequate for rearing O. aenescens larvae. Protein content was important for maximum larval emergence and for F1 adult longevity and fecundity. Adult diet of powdered milk, sugar and dried meat powder was sufficient for maintenance of adult O. aenescens flies. Protein was needed in adult diet for optimal fecundity. Cyromazine was toxic to O. aenescens at high levels (1.0 ppm), but at 0.75 ppm O. aenescens tolerated cyromazine better than a susceptible strain of house flies. At these cyromazine levels, mass release of O. aenescens into poultry houses is possible one to two days after cyromazine has been removed from the chicken feed. The effect of temperature and manure moisture on O. aenescens was studied. At temperatures of 18°C, emergence of Ophyra aenescens was significantly lower than at temperatures of 21 and 27°C. Predation by O. aenescens at 27°C on house fly larvae was significant at ratios of 3:1, 2:1 and 1:1 (house fly to O. aenescens). A constant manure moisture was important in the development of O. aenescens larvae and its ability to prey on house fly larvae. At constant levels of 50, 60, and 70% manure moisture, O. aenescens substantially reduced house fly larval numbers at ratios of 3:1, 2:1 and 1:1.

Resumen

Ailanthus altissima (Mill.) Swingle is a tree native to Asia that was intentionally introduced into the United States in the late eighteenth century. Ailanthus altissima has become an invasive species that has spread throughout most of North America. Lack of effective management tactics for suppression of A. altissima has lead to alternate control methods. Investigations into using biological control with the weevil Eucryptorrhynchus brandti were initiated in 2004. Studies were conducted to understand the general biology of E. brandti, rearing efficacy, and host specificity. Eucryptorrhynchus brandti is univoltine, has a life cycle similar to the closely related species Cryptorhynchus lapathi (L.), with 6 instars, and completes development in 126 Â± 6.5 d at 25Â°C. Efficient egg to adult rearing was accomplished by caging 12 m and 12 f for 7 days on 23 â 92 cm long billets. Males and females can be differentiated by the structure of the metathoracic sternite and 1st abdominal segment. Host specificity experiments show that E. brandti preferentially feeds on North American A. altissima when tested against 29 species from 14 families. Larval development in the rare species Leitneria floridana Chapm. was apparent. Additional studies show that A. altissima does not occur across L. floridana distribution but may have the potential to invade L. floridana sites.

Resumen

Tanto as técnicas de controle biológico quanto a Técnica do inseto estéril (TIE), são utilizadas em vários países para o controle, supressão e até mesmo erradicação de moscas-das-frutas e outras pragas da agricultura, pecuária e saúde publica. O uso de tais técnicas minimiza o emprego contínuo de inseticidas, protege o ambiente e se adequa aos padrões de segurança alimentar. No entanto, é necessário para a implementação de tais programas, tecnologia para produzir milhões de parasitóides e a própria praga em laboratório com qualidade biológica similar aos insetos encontrados na natureza e com custo competitivo com o controle químico. Os objetivos deste trabalho foi estabelecer protocolos para criação artificial de A. sp. 1 aff. fraterculus em dieta larval líquida que permita atingir níveis de criação massal, para uma possível diminuição no custo da criação e determinar a dose de radiação esterilizante para adultos de A. sp. 1 aff. fraterculus atendendo os parâmetros de qualidade exigidos pela Técnica do Inseto Estéril com insetos provenientes da criação do Laboratório de Radioentomologia do CENA/USP. Foram testadas sete dietas em relação à dieta convencional utilizada no laboratório de Radioentomologia do CENA/USP, que foi usada como controle. Todas as sete dietas tiveram em comum a exclusão do ágar na sua formulação. Somente duas das dietas testadas foram adequadas para o desenvolvimento larval da mosca, estas quando comparadas com a dieta padrão, apresentaram resultados inferiores com relação ao volume de larvas recuperadas, emergência e o peso das pupas, porém, não apresentaram diferenças significativas quanto aos períodos de desenvolvimento, recuperação pupal, razão sexual e longevidade sob estresse. Concluí-se que é possível a substituição da dieta com ágar por dietas líquidas para criação artificial de A. sp.1 aff. fraterculus, de custo reduzido e com maior praticidade de manejo,porém devidos aos seus parâmetros de qualidade inferiores aos da dieta padrão, são necessários maiores testes principalmente quanto à adaptabilidade do inseto ao novo meio. Para determinar a dose esterilizante o presente trabalho analisou a fertilidade, fecundidade, emergência, habilidade de vôo e longevidade sob estresse de A. fraterculus irradiadas com doses de 40, 50, 60, 70 e 80 Gy. A fonte de radiação gama foi um irradiador de Co-60 (Gammabeam-650) localizado no mesmo laboratório. Os testes foram realizados sob as seguintes condições ambientais: 26 ± 1 ° C, 70 ± 5% RH, e fotofase de 12:12. A dose de r adiação gama esterilizante para machos de A. sp. 1 aff. fraterculus foi determinada sendo 70 Gy. Fêmeas irradiadas, mesmo com a dose mais baixa de 40 Gy, não ovipositaram, possivelmente pela atrofia dos ovários causada pela radiação. A radiação não afetou os demais parâmetros de qualidade do inseto como emergência, longevidade e habilidade de vôo
Both the biological control techniques as the Sterile Insect Technique (SIT), are used in many countries to control, suppress and even eradicate fruit flies and other pests in agriculture and public health. The use of such techniques minimizes the continuous employment of insecticides, protects the environment and conforms to standards for food safety. However, it is necessary to implement such programs, technology to produce millions of parasitoids and the pest in its own laboratory with biological quality similar to the insects found in nature and cost competitive with chemical control. The objectives of this study was to establish protocols for artificial rearing of A. sp. 1 aff. fraterculus in liquid larval diet that will achieve levels of mass production for a possible reduction in the cost of establishing and determining the dose of radiation sterilization of adult A. sp. 1 aff. fraterculus meeting the quality parameters required by the Sterile Insect Technique with insects from the creation of Radioentomologia Laboratory of CENA / USP. Seven experimental diets compared to the conventional diet used in laboratory Radioentomologia of CENA / USP, which was used as control. All seven diets have in common the exclusion of agar in its formulation. Only two of the diets tested were suitable for larval development of the fly, they compared with the standard diet, showed inferior results with respect to the volume of recovered larvae, pupae and weight of emergency, however, no significant differences regarding the periods of development , pupal recovery, sex ratio and longevity under stress. It is possible to replace the diet with agar for liquid diets for artificial creation of A. sp.1 aff. fraterculus, reduced cost and greater convenience of handling, but due to their quality standards lower than the standard diet, more tests are needed especially regarding the adaptability of the insect to the new environment. To determine the sterilizing dose this study examined the fertility, fecundity, emergence, flight ability and longevity under stress in A. fraterculus irradiated with 40, 50, 60, 70 and 80 Gy. The radiation source was a gamma irradiator with a Co-60 (Gammabeam-650) located in the same laboratory. The tests were performed under the following environmental conditions: 26 ± 1 ° C, 70 ± 5% RH and photoperiod of 12:12. The dose of gamma radiation sterilization for male A. sp. 1 aff. fraterculus was determined with 70 Gy. Irradiates females, even with the lower dose of 40 Gy, layed no eggs, possibly due to atrophy of the ovaries caused by radiation. The radiation did not affect the other quality parameters such as insect emergence, longevity and ability to fly

Resumen

Abstract This chapter discusses the environmental impact of insect rearing. Direct greenhouse gas (GHG) emissions from insects used as feed or food are discussed and data from life cycle assessments (LCAs) on commercially farmed insects are discussed per species. The relevance of the utilized feed on the environmental impact of insects and their derived products, including suggestions to lower this impact are also discussed. It is concluded that land use associated with insect production generally seems low, compared to conventional feed and food products. The EU (expressed as fossil fuel depletion) of insect production is often high compared to conventional products. To a large extent this is because several LCAs have been conducted for systems in temperate climates, which require extensive climate control.

Resumen

Abstract The chapter highlights the potential benefits associated with the use of insect-rearing residues as biofertilizers while exploring the mechanisms by which chitin in insect frass might control common crop pathogens. The potential benefits for soil fertility derived from the use of insect frass, comparison of quality of insect-derived biofertilizers and common organic and inorganic fertilizers and insect frass and plant health improvement are discussed. While more research is essential to understand the true value of insect-derived biofertilizers for plant and soil health, preliminary findings suggest there are significant opportunities for beneficial impacts in agriculture and horticulture to be realized.

The factors that determine the conditions for creating a thermodynamic model when designing an air conditioning system for growing insects are analysed. The stages of building a thermodynamic model for the design of a subsystem for providing hygrothermal conditions for insect rearing are formed. The structure of the initial data for the construction of air treatment processes in thermodynamic systems with the provision of optimal technological parameters of the technocenosis. Using a thermodynamic model of the microclimate creation system in the d-h diagram of humid air, studies of heat and mass-humidity treatment processes provide information on the required load and volume of systems for providing abiotic factors. Using the method of graphical analysis, it is possible to determine the optimal methods of controlling the polytropic processes of preparing the air of the abiotic environment until it reaches certain temperature and humidity characteristics.

Resumen

In the paper there are presented the results of the researches of existing methods of quality control for cultures of insects for rearing is presented. It is shown that there is a need to search for new approaches to solving this problem. Testing of new methods of control and prediction of biological material viability was carried out on a laboratory culture of the fall webworm moth (Hyphantria cunea Drury). It was found that intensity of taxis manifestation can be considered as a criterion of population condition. This selection method can be used also for assessment of culture viability. A new express-method of biological material selection for H. cunea establishment has been approbated. It is based on the positive correlation between insect viability parameters and their trophotaxis intensity. This method may be suitable for monitoring of natural populations condition in systems of integrated plant protections of different agricultural, ornamental and forest crops with intensive anthropogenic loading.

Resumen

The article analyses the experimental results of the cage area effect on green lacewing productivity. The tests were made under the conditions of the complete green lacewing (Chrysoperla carnea) rearing process on the base of the Engineering and Technological Institute “Biotekhnika” of NAAS of Ukraine in partnership with the the Latvia University of Life Sciences and Technologies. The research was focused on the correlation between the larvae cage productivity and its inner area. Four cage types with the same design and different areas were studied in the experiments. The set of experiments includes parallel insect rearing in three cages of each type. The specific productivity in cocoons·cm-2 was chosen as the main cage efficiency parameter. The analyses showed the productivity reduction with the cage area increasing. However, in the range of the cage area of 550-950 cm2 the average productivity kept constant of 0.64 cocoons·cm-2. The detected interval could be used for cage manufacturing and further equipment set forming with increased economic efficiency. The cage number in such equipment set would be 1.5 times less in comparison to the basic one for the same set productivity. Therefore, the equipment set manufacturing and maintenance costs would be decreased.

Resumen

The gut microbiota affects silkworm growth and development and is particularly associated with food absorption, nutrient use, and disease immunity. The behaviour and evolution of insects are inuenced by interactions with their microbiome. In cases of nutritional deciency or other health conditions, certain microbes can be given as dietary supplements to promote insect reproduction, food conversion, and growth as well as health parasitic infection. An overview of insect-microbiota interactions is provided, as well as information on the function of probiotics, their typical application in the rearing of insects for food and feed, and their interactions with the host microbiota. The improvement of the silkworm's growth and development is greatly aided by nutrition

Resumen

The primary objective of this research is to determine if plastics-degrading gut bacterial communities from a nonoptimal insect host can be successfully transplanted into the gut of the optimal mealworm host for large scale composting. To achieve this goal, foundational questions about basic mealworm husbandry needed to be addressed, including proper housing and feeding regimes, expected plastics degradation rates, and survivability on plastics as a food source. This technical note serves as a mealworm husbandry protocol and a guide for lessons learned in the early stages of experimentation dealing with establishment of plastics-degrading mealworm colonies.

We have chosen heat and desiccation tolerance as prime traits to be enhanced in order to increase the overall efficacy of these nematodes against insect pests under harsh conditions. Initially, we used mutagenesis and selection approaches to enhance these traits. In the mutagenesis experiments several morphological mutants of Heterorhabditis bacteriophora HP88 were isolated and characterized phenotypically and genetically. Infective juveniles of H. bacteriophora HP88 were subjected to heat and desiccation selection regimes for several generations. Small increase was recorded, after 4 and 6 rearing cycles for both traits. However, in both selection regimes a significant deterioration in the reproductive capability of the nematodes was observed. In a screen of new nematode populations, from arid regions in Israel, a heat tolerant (IS5 strain) and desiccation tolerant (IS6 strain) were isolated. Both strains were taxonomically identified and their beneficial characteristics (environmental tolerance, insecticidal virulence and reproduction) were determined. We further investigated the stability of the enhanced heat tolerance trait in, and the storage capacity of, the newly discovered IS5 strain. Genetic studies demonstrated that the heat tolerance of the IS5 strain is genetically based and is dominant. The trait for heat tolerance was transferred from the IS5 strain to the HP88 strain of H. bacteriophora. The transfer was accomplished by allowing the heat tolerant strain (IS5) to mate with the commercial strain (HP88). The hybrid nature of the progeny was confirmed using a recessive marker mutant of the HP88 strain (H-dpy-2). We have used (RAPD-PCR) to compare genetic variation in the IS5 and the HP88 strains of H. baceriophora. The results indicated that genetic variation in the HP88 was significantly less than in the IS5 strain which was recently isolated from the field. The new IS5 strain may be used as an effective biological control agent in warm environments. In addition, IS5 can be used as a genetic source for cross-hybridization with other H. bacteriophora strains.

Resumen

i. List the original objectives, as defined in the approved proposal, and any revisions made at the beginning or during the course of project. Our objectives were: 1) develop state-of-the-art functional genomics tools for B. terrestris. These resources will be then used to: 2) characterize genes and molecular pathways that are associated with reproduction, 3) characterize genes and molecular pathways associated with specialization in foraging or nursing activities, and 4) determine the extent to which juvenile hormone (JH) is involved in the regulation of reproduction and division of labor. 5) Use RNA interference to down regulate genes associated with reproductive physiology, division of labor, or both. A decrease in the cost of RNA sequencing enabled us to further use the BARD support to extend our research to three additional related projects: A) The regulation of body size which is crucial for understanding both reproduction (castedetermination) and (size based) division of labor in bumblebees. B) Analyze RNA editing in our RNA sequencing data which improves the molecular understanding of the systems we study. C) The influence of JH on the fat body in addition to the brain on which we focused in our proposal. The fat body is a key tissue regulating insect reproduction and health. ii. Background to the topic. Bees are by far the most important pollinators in agricultural and natural ecosystems. The recent collapse of honey bee populations, together with declines in wild bee (including bumble bee) populations, puts their vital pollination services under severe threat. A promising strategy for circumventing this risk is the domestication and mass-rearing of non-Apis bees. This approach has been successfully implemented for several bumble bees including Bombusterrestris in Israel, and B. impatiens in the US, which are mass-reared in captivity. In spite of their critical economic and environmental value, little is known about the physiology and molecular biology of bumble bees. In this collaborative project we developed functional genomics tools for the bumble bee B. terrestris and use these tools for a first thorough study on the physiology and molecular biology of reproduction, dominance, and division of labor in a bumble bee. iii. Major conclusions, solutions. The valuable molecular data of this project together with the functional tools and molecular information generated in this BARD funded project significantly advanced the understanding of bumblebee biology which is essential for maintaining their vital pollination services for US and Israel agriculture.

Resumen

Despite the rapid increase in reliance on bumble bees for food production and security, there are many critical knowledge gaps in our understanding of bumble bee biology that limit their colony production, commercial management, and pollination services. Our project focuses on the social, endocrine, and molecular processes regulating body size in the two bumble bee species most important to agriculture: Bombus terrestris in Israel, and B. impatiens in the USA. Variation in body size underline both caste (queen/worker) differentiation and division of labor among workers (foragers are typically larger than nest bees), two hallmarks of insect sociality which are also crucial for the commercial rearing and crop pollination services of bumble bees. Our project has generated several fundamental new insights into the biology of bumble bees, which can be integrated into science-based management strategies for commercial pollination. Using transcriptomic and behavioral approaches we show that in spite of high flexibility, task performance (brood care or foraging) in bumble bee colonies is associated with physiological variation and differential brain gene expression and RNA editing patterns. We further showed that interactions between the brood, the queen, and the workers determine the developmental program of the larva. We identified two important periods. The first is a critical period during the first few days after hatching. Larvae fed by queens during this period develop over less days, are not likely to develop into gynes, and commonly reach a smaller ultimate body size compared to workers reared mostly or solely by workers. The facial exocrine (mandibular and hypopharangeal) glands are involved in this queen effect on larva development. The second period is important for determining the ultimate body size which is positively regulated by the number of tending workers. The presence of the queen during this stage has little, if at all, influence. We further show that stressors such as agrochemicals that interfere with foraging or brood care specific processes can compromise bumble bee colony development and their pollination performance. We also developed new technology (an RFID system) for automated collection of foraging trip data, for future deployment in agroecosystems. In spite of many similarities, our findings suggest important differences between the Eurasian model species (B. terrestris) and the North American model species (B. impatiens) that impact how management strategies translate across the two species. For example, there is a similar influence of the queen on offspring body size in both species, but this effect does not appear to be mediated by development time in B. impatiens as it is in B. terrestris. Taken together, our collaboration highlights the power of comparative work, to show that considerable differences that exist between these two key pollinator species, and in the organization of young bumble bee nests (wherein queens provide the majority of care and then transition away from brood care) relative to later stages of nest development.
