Connolly, Trevor Allan. "The Potential for Re-Invasion by Mammalian Pests at Maungatautari Ecological Island." The University of Waikato, 2008. http://hdl.handle.net/10289/2394.
Full textAbstract:
Mammalian pests are excluded from Maungatautari Ecological Island by an XcluderTM pest-proof fence. Inevitably, the fence integrity will be compromised at some point by mechanisms such as treefall and flood-scour: such events could lead to pest re-invasion. Knowledge of pest activity directly outside the reserve would assist reserve managers in developing optimal breach-response procedures. This thesis described baseline data on the presence, timing of activity and behaviour of mammalian pest animals found directly at the Maungatautari fence. Two seasonal video studies investigated the effects of season (summer and winter), exterior habitat (forest and pasture) and simulated breach type ('tree-fall' and 'flood scour') on the number of pest sightings. Significantly more sightings were recorded in summer (788) than in winter (428), particularly for rodents. Rabbits were sighted significantly more often at pasture sites, but habitat type did not significantly affect sightings of any other species; nor did breach type affect sightings of any species. Ship rats were commonly sighted within the fence hood gutter. Overall, rodent, possum and cat sightings were very high, and mustelid sightings extremely low, in both seasons. Over 95% of non-lagomorph sightings were nocturnal, and the greatest threat of invasion was found to come nocturnally, from mice, and in the summer. A probability model showed that although the cumulative probability of a mammalian pest encountering a fence breach increases dramatically after dark, in reality there is always a threat of encounter, and this is always increasing with time. Over the same two studies, the behaviour of pest mammals sighted was also described. Pests were found to show interest in and enter summer breaches more often than winter breaches (p lt 0.001). Simulated breaches were encountered by pests within the first 24 hours at a very high rate (95% summer, 92.5% winter), and most likely to enter a breach were rodents. Over 7 days, breaches were encountered and entered by increasing numbers of species and possibly by more individuals; all species were shown to be willing to enter. The threat of invasion by ship rats was probably underestimated because of their higher activity within the fence hood than at the fence base; mustelids may also offer a greater threat than the results suggest, because they almost always entered a breach. It was strongly recommended that when the fence integrity is compromised, physical response should be as quick as possible, especially at night. Future research was strongly encouraged, particularly to understand invasion behaviour of animals such as ship rats and stoats, and to describe pest behaviour at real breach events.

As our understanding increases of how pest species receive and process sound, more relevant sonic devices may be developed. The allure of sound as a treatment for pests will remain into the future—motivated by the fact that if they are successful they will be more environmentally friendly and safer for humans.

This research is a study of pest management systems in Malmö. Malmö is, as many other cities, growing and a node of people's movement. Occurrences of pests have increased in the last decade; this increase is attributed to travel as well as construction and building.What this paper shows is that the structures of pest management must evolve to be more communicative and collaborative. The thesis also adds to the housing crisis debate, as pests in one’s housing have a physical as well as psychological effect.

Syftet med vår studie var att ta reda på hur förskolläraren ser och upplever stress samt hur de arbetar för att undvika stress. Vi utgick från syftet när vi formulerade våra frågeställningar och frågorna besvarades därefter utifrån förskollärarens perspektiv på begreppet stress. I den tidigare forskningen får läsaren en bredare förståelse för stress, vilket skapar en helhet av arbetet. För att förstå det insamlade materialet använder vi oss av teroierna krav-kontroll-stödmodellen samt KASAM. I metodvalet utgick vi från en kvalitativ undersökningsmetod, där vi intervjuade varje enskild person för att sen bearbeta och se mönster kring hur de fyra respondenterna såg på begreppet stress. I vårt resultat analyserade vi sen vad förskollärarna hade för erfarenheter av stress och stressorer samt hur de arbetade för att underlätta sitt dagliga arbete. Genom det insamlade materialet och i kombination med teorier samt tidigare forskning, diskuterade vi empiri och såg mönster som återkom. Vi kom fram till att förskollärarna som vi intervjuade hade strategier för hur de skulle arbeta, men de hade svårt att utföra arbetet när kraven ökade och stödet minskade. Alla fyra respondenterna strävad efter att ge barnen de bästa förutsättinngarna, där omsorg, lek och lärande gick hand i hand.

Full textAbstract:
Diese Arbeit beschäftigt sich mit der Erforschung von Yersinia (Y.) pestis in historischem Skelettmaterial. Die Disziplin Paläomikrobiologie verspricht, Beweise zu liefern, die durch die Erforschung moderner Pathogene nicht möglich wären und dadurch möglicherweise das Verständnis zu historischen Infektionen zu verändern (Tsangaras & Greenwood 2012).
Yersinia pestis als der Erreger der Pest wird für drei Pandemien der Menschheitsgeschichte verantwortlich gemacht: die Pest der Moderne, den Schwarzen Tod im 14. und den nachfolgenden Jahrhunderten sowie die Pest des Justinian.
Diese Dissertation beschäftigte sich mit dem Nachweis und der Typisierung des Pest-Erregers in historischen Individuen verschiedener Fundorte aus den beiden letztgenannten Pandemien. Dazu wurden methodisch zwei Wege beschritten: Der Nachweis des Erregers auf molekulargenetischer Ebene durch die Detektion verschiedener Loci und ein davon unabhängiger alternativer Weg zur Detektion des Pathogens über den Nachweis seines Kapselproteins. Letzten Weg zu beschreiten, ist in dieser Arbeit nicht geglückt. Dafür waren die auf Polymerase-Ketten-Reaktion (PCR) beruhenden Ansätze umso erfolgreicher.
Für die Analysen standen Individuen von vier Fundorten in Deutschland und der Schweiz aus unterschiedlichen Zeitstellungen zur Verfügung. Die Skelette des Gräberfelds Aschheim-Bajuwarenring datieren ins 6. Jahrhundert, die Individuen aus Manching-Pichl und Basel ins 14. bis 17. Jahrhundert und die skelettalen Überreste von drei Menschen aus Brandenburg in die Zeit des Dreißigjährigen Kriegs.
Nach der Erprobung eines für das zur Verfügung stehende Material optimal geeigneten Extraktions-Protokolls und der Etablierung neuer PCR-Protokolle wurden die Verfahren auf Extrakte alter DNA (aDNA) angewandt. Dabei wurde zur Generierung authentischer Ergebnisse im neu etablierten aDNA-Labor des ArchaeoBioCenters der LMU gearbeitet, das die maximalen Möglichkeiten der Verhinderung von Kontaminationen bereitstellt.
Es ist in dieser Arbeit gelungen, bereits publizierte Pest-Nachweise in Skeletten aus Aschheim und Manching-Pichl zu reproduzieren und damit zu validieren. Darüber hinaus konnte in Individuen eines weiteren, bisher molekulargenetisch nicht untersuchten Fundorts in Brandenburg die Anwesenheit der Pest gezeigt werden. Durch tiefer gehende molekulargenetische Untersuchungen anderer Loci sowie Single Nucleotide Polymorphismen (SNP) wurden die jeweiligen Erreger in einen bereits existierenden phylogenetischen Stammbaum eingeordnet.
Durch den Beweis der Anwesenheit der Pest in Aschheim im 6. Jahrhundert wurde das Bakterium Yersinia pestis eindeutig als Verursacher der ersten Pandemie identifiziert – eine Assoziation, die nach anfänglichem Konsens zuletzt in Frage gestellt worden war. Spekulationen um das ätiologische Agens können jetzt definitiv eingestellt werden. Die Ergebnisse dieser Arbeit beenden auch weitere Diskussionen bezüglich des Biovars des Erregers während der ersten Pandemie. Durch Typisierungen wurde gezeigt, dass es sich bei diesem Erreger um einen anderen handelt als den, der für die zweite oder dritte Pandemie verantwortlich ist.
Der Nachweis und die Typisierung des Erregers im Zuge des Schwarzen Todes in Manching-Pichl und Brandenburg schließt die bis dato existierende genauer charakterisierte Detektionslücke in Deutschland. Bisher waren nur in England, Frankreich und den Niederlanden der bzw. die Erreger durch zwei Arbeitsgruppen aus Mainz und Tübingen/Kanada glaubhaft detektiert worden. Der in Deutschland identifizierte Erreger passt dabei zu den Ergebnissen der anderen Fundorte in Europa. Zudem scheint es in Deutschland über einen längeren Zeitraum nur einen Erregertyp gegeben zu haben, da die Ergebnisse der Individuen aus Brandenburg und Manching-Pichl in allen untersuchten Loci genau übereinstimmten.
Obwohl aufgrund ungenügenden Quellenmaterials nicht exakt belegbar scheint der Weg der Pest zu diesen beiden letztgenannten Fundorten in Deutschland ein anderer gewesen zu sein als der zu den anderen europäischen Fundorten.

Full textAbstract:
Antifeedants and growth regulators have potential as alternatives to conventional methods of insect pest control. As with conventional chemicals it is important to consider their effects on natural enemies of the pests. The aim of this project was to determine whether the bitter-tasting synthetic chemical denatonium benzoate as an antifeedant and compare with neem derivatives. Other aims were to investigate their effect on parasitoids and the field infestation of cabbage pests. Denatonium benzoate is systemic and had no contact effect but acted as an antifeedant on a generalist sap feeder Myzus persicae and reduced the survival, fecundity, and lifespan. Neem derivatives, Azatin EC and Pestistat R were more effective of which Azatin EC was the most effective. Antifeedants further reduced the fecundity and survival when parasitized with its parasitoid, Aphidius matricariae and neem derivatives had adverse effects on both aphid and the parasitoid. Denatonium benzoate and Pestistat R with a specialist leaf feeder, Pieris brassicae and all antifeedants with Plutella xylostella (generalist leaf feeder) and Chrysodeixis eriosoma (specialist brassica leaf feeder) reduced the leaf area consumed and it was inversely proportional to the concentration. The highest leaf area consumption was in denatonium benzoate and the lowest in Pestistat R. Higher azadirachtin concentrations were detrimental but denatonium benzoate was safer to the larval parasitoid, Cotesia plutellae. Denatonium benzoate and Azatin EC reduced field infestation of M. persicae, P. xylostella and C. eriosoma in Peradeniya, Sri Lanka and Azatin EC was the most effective. Denatonium benzoate acts as an antifeedant against cabbage pests and safer towards parasitoids hence can be used in integrated pest management programmes. Neem derivatives are comparatively more effective on pests but harmful to parasitoids. Denatonium benzoate and Azatin EC effectively reduced the pest infestation under field conditions.

Full textAbstract:
During World War I, dogs held a contradictory place in American society. These animals functioned simultaneously as patriots, pets, and pests. This essay surveys the ways in which dogs either contributed to the war effort or seemed to subvert it through their uselessness as companion animals and their predation as feral ones. Ultimately, even worsening conditions on the homefront could not cause the American public as a whole to consider surrendering its affection for these animals, including the worthless ones. In the face of impending legislation that threatened to eliminate man’s best friend as a war measure, the American people successfully defended the dog, while citizens in several of the other warring nations could not afford to do so. American admiration for the patriot, combined with affection for the pet, outweighed anxiety over the pest.

Several lepidopteran species infest developing panicles. Larval identification is challenging and time intensive, so current recommendations are often simplified by treating all larvae equally across species. Consequently, the yield-loss model developed for corn earworm (Helicoverpa zea) by Buckley and Burkhardt (1962) has been the foundation for management recommendations in modern sorghum Integrated Pest Management (IPM) programs for the last 49 years. Additionally, although pest populations primarily include both fall armyworm (Spodoptera frugiperda) and corn earworm, only a single species damage estimate is used in economic threshold (ET) and economic injury level (EIL) calculations despite multi-species infestations. This research demonstrates both the validation of current management recommendations for corn earworm and the verification of previously assumed damage potentials for fall armyworm feeding in developing sorghum panicles. These results have important implications for sorghum producers faced with making a management decision for multi-species infestations.

Full textAbstract:
In the light of increasing pesticides resistance in agricultural pests and in insect vectors of human diseases, leading to the rise in occurrence of mosquito-borne diseases, new, efficient and environmentally friendly methods of pest control are needed. Sterile Insect Technique (SIT), relying on mass releases of radiation sterilised males to reduce reproductive potential of target pest populations, although not new, offers an alternative to the use of pesticides and is an environmentally non-polluting method of insect control. Many insect species, however, are not very amenable to classical SIT, due to detrimental side-effects of radiation treatment. We propose a new method, a genetically engineered modification of classical SIT, replacing radiation with genetically induced sterility. Based on conditional expression of male-germline targeted nucleases which introduce double strand breaks into the male germline DNA to render males sterile, this method emulates SIT mechanism, at the same time eliminating radiation and associated detrimental side-effects. Different variants of such a system were investigated in this project, eventually leading to the creation of functional conditional male-sterility systems in two model organisms – the Yellow fever mosquito, Aedes aegypti and the Mediterranean fruit fly, Ceratitis capitata. Both systems utilise chimeric nuclease composed of protamine and FokI cleavage domain fusion. The sperm-specificity and the conditionality of the sterile phenotype have been achieved through the use of tetracycline repressible expression system driven by the β2-tubulin promoter in Ceratitis capitata and by the Topi promoter in Aedes aegypti.

Foliar-applied insecticides and the soil-applied insecticide, Admire, were evaluated for their ability to control citrus mealybug on lemons while having a minimal impact on parasitoids. All of the foliar-applied insecticide exhibited activity towards citrus mealybug. The standard insecticide, Lorsban, performed very well, but since this product is especially harmful to parasitoids it is not considered to have a good fit in IPM programs where parasitoid conservation is emphasized. The currently labeled alternative, Applaud, was an effective treatment and should be considered for citrus mealybug control to avoid destruction of parasitoids. Several experimental insecticides showed promise: NNI-850, NNI-750C and NNI-010. However, NNI-0101 at the lower rate of 0.24 lbs-ai/ac appeared to be weak. The addition of narrow range crop oil, NR-415 at 1.0 gal/ac, appeared to be beneficial for initial mealybug knock-down, especially for the slower acting insecticides such as Applaud. Soil injection of Admire at 16 and 32 oz/ac appeared to have very good activity, but due to variability in the mealybug population, more data should be collected to confirm this finding.

Full textAbstract:
A major challenge in agroecosystems is how to manage the systems so that it reduces crop pests and enhances natural pest control. This thesis investigates patterns of crop pests and top-down effects of birds and arthropod predators in relation to land-use composition across spatial scales. In paper (I) I examined the crop distribution and land-use types in relation to the crop raiding patterns in 15 transectsin sites close to and far from forests along with a questionnaire survey at household level. I found severe crop raiding close to forests, but it had no impact on crop composition growing between the two sites. In paper (II) I examined the effect of forest and tree cover, at local and landscape scales, on the abundance of arthropod predators by collecting specimens from 40 home gardens. My result showed higher abundance of arthropod predators when either the home garden or the surroundings had a high tree-cover, compared to when tree-cover at both scales was similarly either high or low. In paper (III) I investigated the effect of excluding birds and arthropod predators on leaf damage on rape seed in 26 home gardens. I found stronger top-down impacts from arthropod predators on crop pests in tree-poor gardens than in tree-rich gardens. There was no effect of birds. In paper (IV) I explored the effect of landscape complexity on bird and arthropod predation using plasticine caterpillars in 36 home gardens across landscapes. The rate of arthropod predation on caterpillars was higher in simple than in complex landscapes. The rate of bird predation did not vary between complex and simple landscapes. In simple landscapes, arthropod predation was higher than that of birds. The overall results suggest that simplified gardens/landscapes still have enough habitat heterogeneity to support arthropod predators for the significant top-down controlling effect on crop pests. However, I did not find clear effect of complexityon the top-down effect of birds.At the time of the doctoral defence the following papers were unpublished and had a status as follows: Paper 1: Manuscript; Paper 3: Manuscript; Paper 4: Manuscript

Full textAbstract:
Les propietats insecticides d’una sèrie d’esters d’al•lil va ésser avaluada en diferents insectes mitjançant diferents modes d’aplicació. L’acció per aplicació tòpica va variar en funció de l’ester d’al•lil aplicat. El cinamat i el naftoat d’al•lil van ser els compostos més actius front a ous i larves neonates de C. pomonella, G. molesta i L. botrana, mentre que el salicilat d’al•lil no va produir mortalitat a la major dosi assajada (10 mg/mL). El cinamat d’al•lil va ser l’únic ester actiu per aplicació tòpica en adults de A. pisum, mentre que tots els esters d’al•lil testatsvan ser actius en adults de T. castaneum.
Els esters d’al•lil assajats van produir una pèrdua de la viabilitat cel•lular en les línees cel•lulars d’insectes quan va èsser mesurda mitjançant dos metodologies diferents (MTT i Blau de tripà), degut a una disrupció de les membranes cel•lulars. El cinamat d’al•lil va ser el compost més actiu i les cèl•lules procedents de l’aparell digestiu de Choristoneura fumiferana (Lepidòpter) les més sensibles. L’acció insecticida per ingestió va ser confirmada en larves de S. littoralis i C. pomonella, i en nimfes de A. pisum, senyalant l’aparell digestiu com a principal punt d’acció dels esters d’al•lil.
Els corresponents àcids i dicloropropilesters van mostrar una menor o igual acció insecticida que els corresponents esters d’al•lil, deguda també, a una acció en la membrana cel•lular. Les diferències en l’acció dels compostos seria deguda a diferències en les propietats lipofíliques dels compostos i la seva interacció amb les membranes cel•lulars.
Pel que fa a l’efecte dels esters d’al•lil en la comunicació química dels insectes, aquesta va tenir lloc en T. castaneum però no en A. pisum, el que es podria utilitzar per a mantenir els productes enmagatzemats lliures de T. castaneum. Pel que fa a C. pomonella i a L. botrana, tots els esters d’al•lil assajats van produir una resposta en les antenes dels mascles de C. pomonella, però tan sols el cinamat d’al•lil la va provocar en les femelles de C. pomonella i en mascles i femelles de L. botrana. Aquesta acció no es va veure reflexada en un increment de l’atracció de mascles cap a fonts amb l’ester d’al•lil i feromona en assajos en túnel de vent, però si en l’atracció de femelles. Aquest fet podria utilitzar-se per a incrementar el nombre de captures de femelles en trampes de feromona.
Aquests resultats suggereixen un paper dels esters d’al•lil en el control de plagues, especialment del cinamat d’al•lil.La acción insecticida de varios esteres de alilo fue testada en diversos insectos y mediante distintos modos de aplicación. La actividad por aplicación tópica varió en función del éster de alilo. El cinamato de alilo y el naftoato de alilo fueros los compuestos más activos en huevos y larvas neonatas de C. pomonella, G. molesta y L. botrana, mientras que el salicilato de alilo no produjo mortalidad a la dosis más alta testada (10 mg/mL). El cinamato de alilo fue el único éster activo por aplicación tópica en A. pisum mientras que todos los esteres testados lo fueron para T. castaneum. Los esteres de alilo estudiados produjeron pérdida de viabilidad celular en todas las líneas celulares de insectos cuando dicha viabilidad fue analizada mediante dos metodologías distintas (MTT y Azul de Tripano), y siendo ésta debida a la disrupción de la membrana celular. El cinamato de alilo fue el producto más activo, y las células del aparato digestivo de Choristoneura fumiferana (Lepidoptera) las más sensibles. La acción insecticida por ingestión en larvas de S. littoralis y C. pomonella, y en ninfas de A. pisum, fue confirmada y el aparato digestivo fue señalado como principal punto de acción de los esteres de alilo. Los correspondientes ácidos y dicloropropilesteres presentaron una menor o igual acción insecticida que los esteres de alilo siendo dicha acción también debida a un efecto en la membrana celular. Las diferencias en la acción de los distintos compuestos podrían ser debidas a diferencias en las propiedades lipofílicas de los compuestos y su interacción con las membranas celulares. Los esteres de alilo produjeron un efecto en la comunicación química de T. castaneum pero no en A. pisum, lo que podría utilizarse para mantener los productos almacenados libres de T. castaneum. En cuanto a C. pomonella y L. botrana, todos los esteres de alilo probados produjeron una respuesta en las antenas de los machos de C. pomonella, mientras que tan solo el cinamato de alilo la produjo en las antenas de hembras de C. pomonella y en machos y hembras de L. botrana. Esta respuesta no se tradujo en un aumento de la atracción de machos hacia cebos con mezclas de ester de alilo y feromona en ensayos de túnel de viento, pero si aumentó el número de hembras atraídas. Este hecho podría utilizarse par incrementar el número de hembras capturadas en trampas de feromona. Estos resultados, sugieren el papel de los esteres de alilo en el control de plagas, especialmente del cinamato de alilo.

Full textAbstract:
Pest risk assessment is an essential yet problematic stage in pest risk analysis (PRA) that concerns the likelihood and consequences of pest introduction. The aim of this study was to develop methodologies for risk assessment and to explore different approaches that could lead to the development of new methods for practical PRA in line with the requirement of "scientific justification" by World Trade Organisation and Food and Agriculture Organisation of the United Nations. Current international practices were discussed and research reviewed on qualitative and quantitative approaches to risk assessment. It was proposed that risk assessment be divided into two steps: Pest risk identification (PRI) and pest risk evaluation (PRE). Mind Mapping was a valuable tool for PRI that reduced ambiguity and increased transparency. Approaches to PRE were proposed that facilitated the scoring and weighting of risk factors, and the subsequent combining of risk scores. Several methods were developed to incorporate weighting into PRA, which included subjectively assigned weighting and Delphi technique-derived weighting. Metrics for combining risk scores into an overall risk value were also explored, compared and evaluated. Correlation and interaction between risk factors were analysed, which revealed that some risk factors were highly correlated and some were relatively independent, which meant there was some information redundancy, and therefore simplification of risk assessment was possible. Cluster analysis was applied to risk factor scores and different clusters of risk factors were identified: some more appropriate for preliminary assessment; some for determining the level of risk; and some could be eliminated. A method to apply Principal Components Analysis (PCA) to derive weighting for individual risk factors was developed. PCA could be applied to historical data of pest introductions, previous PRA cases, or expert opinion. Genetic algorithms implemented in the software BEAGLE, were applied to PRA data. The rules obtained could distinguish high-risk situations with high accuracy, which was useful in predicting the risk of an organism by using a simplified set of conditions. The results showed that weightings and rules differed for different taxonomic groups. Therefore it was implausible to develop a generic scheme in this way. However, it may be possible to develop patterns based on taxonomy. The results of applying several different techniques all suggested that by grouping risk factors for different purposes, risk assessment could be simplified without compromising rigor, because a) some factors were redundant; b) some factors are more important than others; and c) high risk situation could be predicted with a few key factors.

Full textAbstract:
In the management of agricultural insect pests, short-term costs must be balanced against long-term benefits. Controls should be selected to account for both their immediate and downstream effects upon the demography and genetics of the pest, enabling suppression today without threatening suppression tomorrow. The iterative, algorithmic method of dynamic programming can provide optimal solutions to problems of this type, in which actions are taken sequentially and each action may influence those which follow it. However, this approach is fundamentally constrained with regards to the magnitude of the problems it may solve. As questions of insect pest management can be subject to ecological and evolutionary complexities, this may place them beyond the scope of dynamic programming. When it is the intricacies of a problem that are of interest, it may be more productive to utilise approximate dynamic programming (ADP) methods which can attempt problems of arbitrary complexity, although at the expense of no longer guaranteeing optimality. In this thesis I first challenge a dynamic programming algorithm with the management of a hypothetical insect pest feeding upon a transgenic insecticidal crop. The model explores how different realisations of fitness costs to resistance influence the algorithms suggested actions. I then apply a brute-force variant of ADP, a lookahead policy, to the management of a stage-structured, continuously reproducing pest population. This was to explore the extent to which an algorithm with a limited temporal perspective is able to balance the timetable of pest demography against the timescale over which insecticidal sprays and bisex-lethal sterile insect releases unfold. This same decision framework is then applied to a modified problem in which resistance to insecticidal toxins may evolve and releases are now male-selecting. This was used to assess the efficacy with which simple lookahead policies utilise a control with delayed benefits (the male-selecting releases) and possible constraints on their capacity to respond to resistance evolution. Dynamic programming and ADP methods offer a versatile toolbox for accounting for the potential impacts of the evolutionary and ecological peculiarities of particular pests upon control decisions.

For the first time in many decades, a hemp pilot program was initiated in Virginia in 2016. Outdoor surveys were conducted in the 2017 and 2018 field seasons to record insect presence and feeding injury to plants. Multiple insect pests were present, including corn earworm (Helicoverpa zea [Boddie]) (Lepidoptera: Noctuidae), brown marmorated stink bug (Halyomorpha halys [Stål]) (Hemiptera: Pentatomidae), and cannabis aphid (Phorodon cannabis) (Hemiptera: Aphididae). In 2019, indoor production surveys revealed that cannabis aphid, twospotted spider mite (Tetranychus urticae Koch) (Acari: Tetranychidae), and hemp russet mite (Aculops cannabicola [Farkas]) (Acari: Eriophyidae) would likely cause production issues. Very little is known about the impact of insect defoliation in hemp so studies were conducted in 2018-2020 to determine impacts on yield and cannabinoid content of grain and cannabinoid variety hemp due to leaf surface area loss. In Virginia over two growing seasons, manual removal of leaf tissue in grain and CBD cultivars did not significantly impact observable effects on physical yield (seed or bud weight) or cannabinoid content (CBD or THC) at time of harvest. Corn earworm is the major pest of hemp produced outdoors and studies occurred to evaluate monitoring and management strategies. Pheromone traps may be valuable in determining when corn earworm moths are present in the vicinity of hemp fields but are not useful in predicting larval presence in buds or final crop damage. Larval presence and final crop damage are related. Brown marmorated stink bug does not appear to be a concern in hemp, at least at this time.Doctor of Philosophy

Full textAbstract:
The Virginia Integrated Pest Management Expert for Wheat was designed to combine the best available information regarding wheat pest management of disease pathogens, weeds, and insects into a decision support system that would provide potential outbreak risk and pest control information to the Comprehensive Resource Planning System (CROPS). In addition, the system stands alone as an educational tool for farmers and Extension personnel.
This is a rule-based system developed on the Microsoft Windows platform. Knowledge about crops and pest management is represented in the form of IF/THEN rules, demons, and "when-changed" methods. The inference engine analyzes specific crop system information entered by the user to determine potential risks of outbreak for wheat crop pests common to Virginia. These potential outbreak risks are presented as low, medium, and high levels of risk and are presented for each of 15 pests of wheat in Virginia.
The system was evaluated using thirty random cropping system scenarios. By comparing expert system output with output from human experts, it was shown that the expert system agreed with human expert opinions in 84 percent of the decisions made. Statistical analysis of the insect pest data showed that there was no significant statistical difference between the distribution of the human expert predictions and the expert system predictions. Statistical analysis of the disease pest data showed that there were some significant statistical differences between the distribution of the human expert predictions and the expert system predictions.

The aim of this essay is a survey of the Mexican economy. Its strong points and weaknesses shall be found and the international competitiveness of the country will be explored. The instrument of the survey is PEST analysis. The PEST analysis helps to explore the economy from four points of view in order to get a complex image of the country. Several factors, political, economical, social and technological ones, have to be judged together because they influance each other. AT the end of description of each factor, there will be a review of the situation. Problems of the economy will be found, the estimation of future development will be made, eventually innovation suggestions will be placed.

Full textAbstract:
Pests can impact significantly upon the economy, the environment and on human and animal health. However, for pest birds there are surprisingly few studies of these impacts and how to reduce them. The aim of this thesis is to advance our understanding of the ecology, impacts, and management of pest birds using case studies for each of the three main impacts. In considering economic impacts I estimate pest bird abundance, describe a novel method for measuring bird damage, and evaluate the efficacy of lethal and non-lethal methods in vineyards and orchards. Using data across 185 property years, netting was found to be the most effective in reducing bird damage. Shooting was not as effective but was one-third of the cost and had 13% lower damage compared with nil-treatments. Scaring with electronic devices and visual deterrents had no effect on bird damage. Despite their widespread use, lethal methods had limited effectiveness for reducing pest abundance. In considering environmental impacts introduced mallards on Lord Howe Island were used as a case study. Phenotypic characteristics suggest that mallards have supplanted the native Pacific black duck on Lord Howe Island. Management alternatives are evaluated and discussed. In considering health-related impacts wild birds and avian influenza in Australia was used as a case study. Here, the ecology of Australia’s Anseriformes, and the epidemiology, modes of transmission, and the factors influencing the prevalence of avian influenza in Australia’s wild birds are investigated. Risk profiles to improve the efficiency and relevance of wild-bird surveillance are also provided. The case studies presented demonstrate that an understanding of a pest’s ecology, efficient measures of impacts, and thorough evaluations of surveillance and management strategies are essential for effectively managing their economic, environmental and health-related impacts.

Full textAbstract:
Integrated pest management (IPM) is a multi-layered approach to reducing pest pressure, primarily in agriculture, but also in national parks and urban settings. Its purpose is to maintain acceptable levels of productivity whilst avoiding the adverse effects associated with indiscriminate chemical control, such as pesticide resistance, secondary infestation, resurgence and harm to human health and the environment. It is a complex system, science-driven and information-based, and there are a wide range of actors involved in its development and implementation. These actors occupy various social locations. They are grouped in institutions for research and extension, in industry and related associations, in funding bodies, policy-making departments, and agricultural communities. IPM requires concerted
effort from all involved; yet in some cases, social inequality characterises relations between the groups. Consequently, different groups address different layers of the IPM whole. Some groups have greater societal power to promote their developmental activities than others do, and when these differing activities meet in practice, as they must, conflict and contradiction can arise.
This thesis attempts to understand the social construction of IPM by examining the process of IPM development and implementation. It follows the Science and Technology Studies (STS, also termed Science, Technology and Society) theoretical framework of the interrelationship, rather than separateness, of science, technology and society. It examines the way social relations influence
technological developments in IPM, and the way IPM technologies influence social relations.Thesis (PhD Doctorate)

The purpose of this study was to assess the adoption response of cotton growers to Integrated Pest Management (IPM) programs, identify the extension strategies used to promote IPM, and provide descriptive comparison of IPM programs between the foremost eleven cotton-producing states in the United States. Integrated pest management is presented as an alternative agricultural production strategy referred to as sustainable agriculture. IPM programs for cotton were evaluated by use of a survey instrument and telephone interviews with the IPM coordinators for the eleven cotton-producing states. The most significant findings were that programs vary considerably between states; the most widely employed IPM techniques were selective use of chemicals, use of economic thresholds and sampling for pests; the Cooperative Extension Service worked closely with private consultants and grower associations; and adoption of a wide variety of IPM techniques has been extensive for cotton producers in the eleven foremost cotton-producing states.

Zhang, Han. "Promoting integrated pest management in arable fields." Thesis, University of Reading, 2017. http://centaur.reading.ac.uk/76302/.
Full textAbstract:
Integrated pest management (IPM) has gained recognition worldwide as a key tool for sustainable arable farming. Promoting natural pest control, strategic use of insecticides, and farmer participation are three important elements in IPM. However, knowledge gaps exist related to the economic value of natural pest control service, insecticides’ efficacies and side effects, and farmers’ incentives to adopt natural pest control in arable fields. This thesis addresses these gaps using UK and European arable crop systems. With a natural enemy exclusion experiment and economic surplus method, the annual economic value of predators and parasitoids for the summer grain aphid (Sitobion avenae) control in wheat (Triticum spp.) in South East England was estimated to be £0-2.3 Million, depending on the aphid infestation levels. Insecticidal sprays based on action thresholds would enhance the value of this ecosystem service. By conducting a UK online survey among experts on insecticide efficacies and side effects in oilseed rape (Brassica napus) protection, relatively older chemical groups were perceived to have lower efficacies for target arthropod pests than newer ones. Foliar sprays were perceived to have greater negative impacts than seed treatments on users’ health, natural enemies, pollinators, soil and water. Many foliar active ingredients pose potential risks for non-target arthropod species in UK oilseed rape fields. Through an interview of European arable farmers participating in an agri-environmental project, respondents’ willingness to encourage natural (animal) pest control was relatively low. In comparison, using insecticides to control pests was the typical practice. Ordinal logistic regression indicated that farmers’ decision to promote natural pest control was positively associated with the perceived importance of this ecosystem service on crop production, but negatively associated with the perceived number of important pests in the fields. The implications of these findings and avenues for future research to enhance IPM in arable crops are discussed.

Esta dissertação trata do Parque Estadual da Serra do Tabuleiro (PEST), em Santa Catarina/Brasil, e da história de alguns de seus conflitos sócio-ambientais. O PEST está inserido no bioma da Mata Atlântica, qualificado como um dos principais parques de conservação do Brasil, pois seu território abriga vários ecossistemas, tais como Restinga, Araucária, Floresta Pluvial Atlântica, Matinha Nebular, Campos de Altitude e Mangues. A Fundação do Meio Ambiente de Santa Catarina (FATMA), ao longo de sua história como autarquia, tem construído um discurso que busca nomear o PEST como #santuário da biodiversidade. Mas essa área de preservação permanente tem ainda habitantes e seu interior, que vêm sendo retirados ou impedidos de exercerem suas atividades econômicas tradicionais, o que gera inúmeros conflitos e discursos resistentes. Nesse sentido é que o enfoque dado à pesquisa buscou compreender e discutir a formação das Unidades de Conservação (UCs) e suas implicações sociopolíticas na região total do PEST. This dissertation concerns the Serra do Tabuleiro State Park (Parque Estadual da Serra do Tabuleiro - PEST), in the Santa Catarina state, Brazil, and the history of some of its social-environmental conflicts. The STSP is inserted in the Atlantic Forest bioma and it is considered one of the main conservation units in Brazil, for its territory hosts many different ecosystems such as Restinga vegetations, Araucaria pine forests, Atlantic Rainforests, Cloud forests, Altitude fields, and Mangue vegetations. The Santa Catarina State Environment Foundation (Fundação do Meio Ambiente de Santa Catarina # FATMA) has been developing the concept of the STSP as #the sanctuary of biodiversity#, though this permanent conservation unit is inhabited in its countryside; these people have been removed or their economical activities have been obstructed, which has generated countless conflicts. This research has focused on the formation of the Conservation Units (CUs) and the sociopolitical implications within the PEST area.

Full textAbstract:
The main purpose of this thesis work is focused on the use of PEST (Parameter Estimation) to calibrate numerical models of High Enthalpy Geothermal Reservoirs (HEGR). PEST is a parameter estimation and analysis of the uncertainties of complex numerical models tool, that can be instructed to work with a standalone simulator. So, the T2Well-EWASG was used as coupled wellbore-reservoir simulator for multiphase-multicomponent HEGR. The idea of this thesis work is that the possibility to implement some automation degrees in the wellbore-reservoir model calibration task would improve substantially the Reservoir Engineers work. To become familiar with PEST, it has been necessary a preliminary training to learn how to manage its input files, its keywords, and the utility programs having the function of verifying the correctness and consistency of the created files. Then, one of the examples of PEST manual (which Fortran source code is supplied) was reproduced and analyzed, and subsequently modified. In particular, starting from this example, a simple linear model with two free parameters, some changes have been performed: "fixing" a parameter to inhibit its change during the calibration; reading a more complex model output file respect to the original example; inserting dummy data that should not be processed and instructing PEST to consider only the data of interest; changing the model adding parameters to be calibrated, and including them in the analysis changing the PEST inputs files. Finally, these skills were applied to use PEST with T2Well-EWASG to calibrate a numerical model, relative to a real HEGR, previously calibrated via a trial and error approach in a PhD thesis work. Among the real data used there were also short production-tests done in a geothermal field located in the Dominica Commonwealth.
The preliminary results show that the PEST-T2Well-EWASG calibration system works fine, and that it is a useful tool that can improve the work of reservoir engineering.
