Abstract:
The relative ability of apterous and alate morphs of aphids to disperse from one potato leaflet to another was similar within species. Three species were tested: the buckthorn aphid, Aphis nasturtii Kaltenbach, the potato aphid, Macrosiphum euphorbiae (Thomas), and the green peach aphid, Myzus persicae (Sulzer). The average percentage of aphids moving daily from one leaflet to another never exceeded 2.5% for nymphs of the three species, but reached 45% for the adult winged buckthorn aphid. During the first half of the reproductive period, adult potato aphids were 1.5 times as likely as buckthorn aphids and twice as likely as green peach aphids to relocate daily. In a flight chamber, buckthorn aphids flew 4.5 times longer than green peach or potato aphids. The maiden flights of these summer forms were interrupted by repeated landings lasting less than 2 min. The maiden flights were interrupted more than twice as often for the buckthorn aphid as for the potato aphid. The number of flight interruptions was intermediate for the green peach aphid. Selected dispersal parameters for these aphid species are compared with those for the black bean aphid, Aphis fabae Scopoli, an occasional potato-colonizing species. The percentage of green peach and potato aphids taking flight was significantly correlated with the temperature in the flight chamber. The implication of these results for the distribution of aphid populations and the epidemiology of viral diseases is discussed.

Abstract Two formulations containing culture filtrates and conidial suspensions of the endophytic fungus Cladosporium oxysporum Berk. & M.A. Curtis, isolated previously from stems of Euphorbia bupleuroides subsp. luteola (Kralik) Maire, were experimentally tested for their aphicid activity against the black bean aphid Aphis fabae Scop. found in Algeria. It was shown that invert emulsions are more effective against aphids, than using aqueous suspensions. This was especially true for formulations containing culture filtrates. The relatively insignificant mortalities obtained by formulations containing conidial suspensions indicated a low infectious potential towards the aphids. The proteolytic activity seemed to be more important than the chitinolytic activity of the fungus against the black bean aphid A. fabae

Cowpea (Vigna unguiculata (L.) Walp. cv. Caloona), broad bean (Vicia faba L. cv. Aquadulce), and garden pea (Pisum sativum L. cv. Victory Freezer) seedlings were infested with cowpea aphids (Aphis craccivora Koch) or pea aphids (Acyrthosiphon pisum (Harris)), both Homoptera: Aphididae, for 10 days and then infested host plant tissue was examined for foreign substances injected by the aphids. No foreign compound was detected in any of the aphid-infested plant tissues. Both aphid species were also assayed for plant growth substances, utilizing the epinastic response of tomato (Lycopersicon esculentum Mill. cv. Roma Teardrop) seedlings, and both aphid species contained plant growth substances in concentrations higher than plant physiological concentrations. Broad bean and pea seedlings were also treated with foliar and root applications of 6-benzylaminopurine to determine if there were any similarities in plant growth or respiratory responses, following aphid infestation or 6-benzylaminopurine treatment. Root respiration in 6-benzylaminopurine treated plants decreased while shoot respiration increased in a response analogous to that observed for aphid-infested tissue. However, the alternative respiratory pathway was engaged for all 6-benzylaminopurine treatments, whereas in aphid-infested plant roots and shoots it was not. Both 6-benzylaminopurine treated and aphid-infested plants displayed a loss of apical dominance. These data suggest that part of the physiological response of the plant to aphid feeding is induced by changes in the cytokinin to auxin ratio.

Abstract:
ABSTRACT The bacterial communities of aphids were investigated by terminal restriction fragment length polymorphism and denaturing gradient gel electrophoresis analysis of 16S rRNA gene fragments generated by PCR with general eubacterial primers. By both methods, theγ -proteobacterium Buchnera was detected in laboratory cultures of six parthenogenetic lines of the pea aphid Acyrthosiphon pisum and one line of the black bean aphid Aphis fabae, and one or more of four previously described bacterial taxa were also detected in all aphid lines except one of A. pisum. These latter bacteria, collectively known as secondary symbionts or accessory bacteria, comprised three taxa of γ-proteobacteria (R-type [PASS], T-type [PABS], and U-type [PAUS]) and a rickettsia (S-type [PAR]). Complementary analysis of aphids from natural populations of four aphid species (A. pisum [n= 74], Amphorophora rubi [n= 109], Aphis sarothamni [n= 42], and Microlophium carnosum [n= 101]) from a single geographical location revealed Buchnera and up to three taxa of accessory bacteria, but no other bacterial taxa, in each aphid. The prevalence of accessory bacterial taxa varied significantly among aphid species but not with the sampling month (between June and August 2000). These results indicate that the accessory bacterial taxa are distributed across multiple aphid species, although with variable prevalence, and that laboratory culture does not generally result in a shift in the bacterial community in aphids. Both the transmission patterns of the accessory bacteria between individual aphids and their impact on aphid fitness are suggested to influence the prevalence of accessory bacterial taxa in natural aphid populations.

Abstract:
Black bean aphid (Aphis fabae scop.), belongs to order Hemiptera and family Aphididae, is one of the important pests of the Fabaceae family. Beauveria bassiana is an important biocontrol agent to replace chemical insecticides. Therefore, in this research, two different varieties of broad bean with three different concentrations of B. bassiana were investigated on adults of fabae aphids under field conditions. After 3, 5, 7, and 14 days, the effect of the B. bassiana on the population of aphids was measured. The local variety was found to be more sensitive to the aphids compare with the Spain variety. In the high concentration (108 spores/ml), 80% mortality was obtained with B. bassiana in day 3 with local variety; then mortality increased after 5, 7, and 14 days of measuring the population of the adults. Mortality declined with the decrease in concentrations. The Spain variety was found to be resistance because fewer aphids were recorded compared to the local variety. In the highest concentration and day 14, mortality was 100%. The achieved results showed that B. bassiana can be used as a potential biocontrol agent for the management of black bean aphid in the fields.

Abstract:
The seasonal dynamics of aphid Aphis craccivora Koch (Hemiptera: Aphididae) on four bean species namely country bean Lablab purpureus, yard long bean Vigna sesquipedalis, hyacinth bean Dolichos lablab and bush bean Phaseolus vulgaris were studied from September to December 2017 in the experimental field of the Department of Entomology, Bangabandhu Sheikh Mujibur Rahman Agricultural University, Gazipur, Bangladesh. The study also investigated the relationship between the abundance of aphid and its predatory insect lady bird beetle. Aphid abundance on the bean species showed increasing trend from the 4th week of September and reached to the peak during the 2nd week of November and then declined. Bush bean and yard long bean, respectively depicted the higher and lower abundances of aphid throughout the study. Relationship between the abundance of aphid and lady bird beetle on the bean species were positively correlated. Aphid showed negatively correlation with temperature and rainfall, and positive correlation with relative humidity, and the correlations were not significant. Multiple regression equation showed that temperature had the highest effect which contributed 16.1 - 19.2% role on the population of aphid. Bangladesh J. Zool. 48(2): 357-363, 2020

Abstract:
The effects of various densities of cowpea aphids (Aphis craccivora Koch) and pea aphids (Acyrthosiphon pisum Harris), both Homoptera: Aphididae, on the growth of cowpea (Vigna unguiculata (L.) Walp. cv. Caloona), broad bean (Vicia faba L. cv. Aquadulce), and garden pea (Pisum sativum L. cv. Victory Freezer) seedlings were investigated. Within 10 days of infestation, aphid feeding significantly reduced plant dry weights and mean relative growth rates for the six plant–aphid combinations. In all cases except one, the mean unit leaf or net assimilation rate was also significantly reduced within 10 days. The mean leaf area ratio was the same for infested and control plants. The aphid-induced changes in host plants appear to be due to changes in photosynthesis, respiration, and translocate removal from the phloem over the 10-day period. Changes in the growth patterns of the host plant within this period are similar, but the underlying physiological effects could vary among particular plant–aphid combinations.

Abstract:
Ants Alter Insecticide Efficacy on Aphids in the Yard-Long Bean Agroecosystem? This study was aimed to detect the relationship between Aphis sp. and ants and to show whether ants could alter insecticide efficacy on Aphis sp. A survey was conducted in the yard-long bean agroecosystems that have been frequently attacked by aphids and for years treated with imidacloprid insecticide (in Mulyosari Village, intensive sample) versus those barely treated in Ganjar Agung Village (non-intensive sample), both in the West Metro municipal area, Lampung. Two sampling occasions were made (in March and November 2005) where 35 plant parts (i.e. 35 flowers and 35 pods) per sample were randomly observed to record the number of Aphis sp. and ants. The efficacy of the insecticide treatment was determined by comparing the mean number of aphids or ants from intensive versus non intensive samples using a t-test at the 0.05 level. The relationships between ant and aphid numbers were determined by calculating their coefficients of correlation and testing them using a t-test at the 0.01 or 0.05 level. The study showed that the long-term application of the insecticide imidacloprid in the yard-long bean agroecosystem 1) might strengthen the relationship between Aphis sp. and ants (especially Solenopsis sp., Camponotus sp. and Paratopula sp.) and 2) was not effective to suppress Aphis sp. number. Stronger Aphis sp. — ant symbiotic relationship might alter the insecticide efficacy on Aphis sp. in the agroecosystem.

Abstract:
The Black bean aphid Aphis fabae Scopoli (Homoptera: Aphididae) is a serious pest of faba bean, Vicia faba L. (Fabaceae) in Algeria. The use of resistant cultivars may reduce the impact of this pest on broad bean production and at the same time reduce environmental risks and control costs. The level of resistance of fourteen cultivars of broad bean, Vicia faba was screened in the field against the main aphid pest of faba bean, the Black bean aphid, Aphis fabae Scopoli during January to April 2011 in Biskra region (in the east of Algeria). Among the cultivars tested, six cultivars (1, 9, 12, 13, 14 and 15) were the most resistant in the three counts, while three cultivars (4, 6 and 11) were showed a high susceptibility against this aphid at least once. The remainder of cultivars (3, 5, 7, 8 and 10) revealed an unsettled level of resistance. The relationship between the level of resistance and morphological characters of cultivars indicated that the resistant cultivars have a longer leaflet than the high susceptible cultivars. In the other hand, the statistical analysis showed that no significant differences on the plant height and the leaflet width in the tow category of cultivars (resistant and high susceptible).

Abstract:
Common beans (Phaseolus vulgaris) remain an important dietary protein source in Malawi. However, its production is highly hindered by insect pest and disease attack. The study aimed at evaluating the effectiveness of Tephrosia vogelii and Tephrosia candida extracts against bean aphid (Aphis fabae). The evaluation involved two botanical extracts at three different concentrations (0.5%, 2%, and 5% w/v) against bean aphid. Plant extracts (leaves) were air-dried and milled. Powders were then soaked in a 2-litre plastic bucket of cold water. Results indicated that there was significant difference (P<0.05) among treatments. The effectiveness of the treatments was based on reduction in aphid population per plant, pod length, and bean yield. Pod length and bean yield were higher in T. vogelii and Karate as compared to untreated and T. candida. There was a high mortality rate of aphid on the plots treated with T. vogelii compared to plots treated with T. candida at the same concentration. Though these two plant extracts were not as effective as the synthetic insecticide in reducing aphid population, they were considerably and significantly found to be effective; hence, its use by poor-resource farmers is recommended in the protection of bean against aphid.

Abstract:
Behavioural and electrophysiological responses of winged virginoparous Aphis fabae to volatile compounds of faba bean, Vicia faba, were studied and semiochemicals used in host location identified. In olfactometer bioassays, aphids responded positively to V. faba volatiles from an intact plant. This response also occurred when volatiles from an air entrainment sample of a V. faba plant were tested. Coupled gas chromatography-electroantennography revealed the presence of 16 electrophysiologically active volatile compounds in the air entrainment sample and 15 of these were identified as (E)-2-hexenal, (Z)-3-hexen-1-ol, 1-hexanol, benzaldehyde, 6-methyl-5-hepten-2-one, octanal, (Z)-3-hexen-1-yl acetate, (R)-linalool, methyl salicylate, decanal, undecanal, (E)-caryophyllene, (E)-β-farnesene, (S)-germacrene D, and (E,E,)-4,8,12-trimethyl-1,3,7,11-tridecatetraene. A synthetic blend consisting of all identified compounds in the same concentration and ratio as in the air entrainment sample elicited a similar behavioural response from the aphids as the air entrainment sample. Each compound was tested for behavioural activity individually at the same concentration as in the air entrainment sample and subsequently over a range of different doses. It was found that the response to the complete blend was not due to a response to a single compound. Dose response experiments also revealed ten of the compounds elicited negative behavioural responses from aphids. Further behavioural experiments revealed that these responses were context-specific and behavioural activity of individual compounds was different when they were presented alongside other compounds in the blend. It was hypothesised that a blend of host volatiles in a species-specific ratio may be used by A. fabae to recognise its host. To determine whether or not ratios of volatiles could provide a reliable cue to host seeking aphids, intra-specific and diurnal variation of ratios of volatiles emitted were investigated. Although considerable variation in ratios was observed the quantities of some pairs of compounds were positively correlated, indicating a degree of consistency in the ratios.

Abstract:
The maternal rearing environment (MRE) of an organism can be a key determinant of an organism's host choice decisions, its own fitness, or the fitness of its offspring. Here, it is investigated if the MRE of an organism can influence lower or higher trophic levels. A series of reciprocal cross-over experiments was conducted using pea aphids (Acyrthosiphon pisum), bean (Vicia faba) or pea (Pisum sativum) plants, and an aphid natural enemy, the parasitoid wasp Aphidius ervi, as model organisms. In each experiment, pea aphid offspring experienced either the same or an alternative plant host to that experienced by their mothers. This PhD showed that the MRE of pea aphids and parasitoid wasps was not a main contributory factor of host choice decisions or offspring fitness but influenced mother parasitoid wasp fecundity. Additionally, the MRE of pea aphids influenced the foliar nutrient concentration of pea plants when infested with the aphid's offspring. First, over shorter infestation periods, variation in foliar nitrogen and essential amino acid concentrations of pea leaves could be explained by pea aphid MRE. Over longer infestation periods, variation in foliar nitrogen and essential amino acid concentrations of pea leaves was explained by a combination of pea aphid MRE and aphid genotype. Second, the 13C concentration of pea leaf tissue, an indicator of stomatal aperture and leaf water stress, varied with pea aphid MREs over longer infestation periods. However, stomatal conductance and the expression of abscisic acid-responsive genes did not vary in a manner that was consistent with leaf water stress. Additional components of an organism's maternal rearing conditions are considered, including symbioses, as a more realistic MRE compared with that observed in nature. Taking account of MREs could provide a better understanding of the factors influencing the fitness of many organisms interacting in natural and managed ecosystems.

Abstract:
Community genetics research investigates the influence of intra-specific genetic variation on species interactions. This rapidly growing research field consists of more than one approach to explore how a significant portion of the environment of a focal species is differentially defined by the expressed genomes of other interacting species. While the basic concept of community genetics is well supported empirically, there is still a set of pertinent issues in need of further investigation. The initial research addressed herein focused on the extent to which the magnitude of a community genetic effect can be moderated when acting in concert with other forces in nature, i.e. the interaction between community genetic effects and the effects of other eco-evolutionary processes such as competition and parasitism. Subsequent research investigated the impact of genetic variation of host plants in agro-ecosystems on the performance (reproductive success) and behaviour (distribution and feeding-site choice) of plant-associated pests such as aphids, especially when pests and their hosts were subject to plant-mediated interactions. In addition, the differential effects of Indirect Ecological Effects (IEEs) and Indirect Genetic effects (IGEs) on the emergence of shared (extended) phenotypes between natural enemies (i.e. biological control agents and phytophagous insects) were examined. I provide clear evidence for significant effects of the genetic variation of host plant on aphid performance, behaviour and intra- and inter-specific competition. My findings also give credence to the concept of reciprocal moderation between plant genotype and aphid competition. I also provide observations on competition that segues into less antagonistic and possibly into a more cooperative form of interaction. In addition, I establish novel systems of economically important crop genotypes, noxious sap-feeding aphid species and root-galling nematodes. I also devise an amalgamated approach to interpret the interwoven set of mechanisms that underpin the observations presented and conclusions drawn. I also provide further investigation on the role of Indirect Ecological Effects (IEEs) between root-knot nematodes and sap-feeding aphids, and demonstrate the influence of in-plant variation on the interaction between the spatially separated plant consumers. Furthermore, I use a quantitative genetic experimental design in order to demonstrate a differential impact of parasitoid genotype on the behaviour of its aphid host. As such, I provide some of the clearest evidence to date that the phenotype of an organism can be the product of the genes expressed in another organism via Inter-specific Indirect Genetic Effects (IIGEs). Finally, I conducted research on epiphytic bromeliads and their associated faunal communities in the tropics. Here I demonstrate that the influence of intra-specific genetic variation of the host plant on the associated ecological communities may be more universal than previously conceived, with a plausible role for such variation in the maintenance of biological diversity. My research provides evidence for the genetic basis of species interactions and, interestingly, a genetic basis for the evolutionary arms-race between foragers and their hosts. My doctoral work adds new evidence to the increasing literature on the evolutionary importance of (Genotype x Genotype) interactions and (Genotype x Genotype x Environment) interactions in shaping the dynamics of pest communities, which in turn can affect plant phenotype and can influence the properties and services of the focal ecosystem in which the inter-players live and interact.

Abstract:
A liquid artificial diet system, which was suitable for bioassay of added compounds, was developed for the glasshouse potato aphid, Aulacorthum solani. The diet supported normal growth and reproduction of this insect. Once established, the artificial diet bioassay system was used to test potential insecticidal activities of a variety of proteins found naturally occurring in plants. Effects on survival, development and fecundity were measured. The lectin found in snowdrop, Galanthus nivalis agglutinin (GNA) was found to significantly reduce the fecundity of A. solani, in terms of parthenogenetic nymph production, when administered in artificial diets at the 0.1% w/v level. No significant reductions in survival were found, although GNA administered in vitro did appear to slow the development of A. solani. Transgenic potato plants expressing GNA were used in a growth room trial to show that the reduction in fecundity with the in vitro trials could be reproduced in planta. Aphids feeding on the GNA-expressing potatoes had a significantly lower cumulative nymph production than those feeding on non- transformed plants. The transgenic plants had no effect on the survival of A. solani. The GNA-expressing plants were tested in a larger scale glasshouse trial and resulted in a significantly slower buildup of aphids when compared to control potatoes, thus confirming the results of the artificial diet bioassays and in planta growth room trials. Immunohistochemical studies were performed to detect the presence of GNA in the gut lumen of A. solani fed on artificial diet containing 0.1% w/v GNA; the lectin was observed to be selectively concentrated in the region of the epithelial membrane in the stomach, suggesting that binding to surface carbohydrates or glycoproteins was taking place. Binding to the gut surface has been suggested to mediate lectin toxicity in higher animals, and other insects. A synergistic effect was observed with transgenic potatoes expressing a double construct encoding GNA and bean chitinase (BCH); A. solani cumulative nymph production on these plants was significantly reduced compared to aphids feeding on control and GNA-only expressing plants. However, interestingly, BCH-only expressing plants did not significantly affect the fecundity of A. solani, although a slight reduction in nymph production was observed. On the basis of reports in the literature that suggested that chitin-binding lectins were toxic to insects, an attempt to isolate the gene encoding the chitin-binding stinging nettle lectin was made. RNA was extracted from nettle rhizomes and used to prepare a cDNA library. Successful library construction was verified. PGR methods and a primary screen of the library were used in an attempt to locate the gene.

Abstract:
Insect pests act as main barrier in enhancing yield potential of Brassica crops. Lipaphis erysimi is considered as one of the most destructive insect species in mustard production due to its voracious type feeding and multiplication. Therefore application of insecticide is inevitable for cultivation of cruciferous crops, although systemic insecticides has been found to be suitable for management of aphid, despite of high cost, residual effect and ecological ramification have necessitated the application of bio and botanical insecticides as novel approach and are recorded significant in research. Aphids having exclusively viviparous parthenogenesis type reproduction from January to March month with the completion of eight generations are helpful in quick mass multiplication. Natural enemies Coccinella spp., Syrphid larvae and bio-pesticide found effective in suppress aphid numbers. Manipulation in sowing dates of mustard crop provides good yield and less incidence of aphid which is proved through research. Lack of environmental resistant varieties has dispensed toward non feasibility of conventional breeding approaches for developing aphid-resistant Brassica. Although application of genetic engineering plan has resulted in moderate success in development of aphid resistance, so far commercialization of such genetically modified crops has not conceivable, intimate the necessity of further insights in to host plant and aphid communication to form effective approach against aphid resistance. Therefore in this chapter the components involved in Brassica aphid communication are highlighted and present statuses and problem in aphid management are discussed.

Abstract:
Russian wheat aphid (RWA) is an international pest on wheat and occurs in most countries where large scale wheat cultivation is practiced. Consequently, considerable efforts have been made to manage RWA globally. The two management options used currently are chemical control and breeding for deployment of resistant wheat cultivars. There are however drawbacks to both of these management practices. Chemical control has a negative impact on the environment, especially other insect groups such as predators, pollinators and decomposers. With widespread and continuous use of the same active ingredients, there is the possibility that RWA can build up resistance against these specific active ingredients. The drawback with resistance breeding is that certain RWA populations can overcome the resistance in the wheat, resulting in new biotypes virulent to the resistant wheat cultivars.

Abstract:
Wheat (T. aestivum) is one of the key food grain crops and is a prominent source of calories and proteins globally. In addition to mushrooming population and rising abiotic stresses in this ongoing climate change era, biotic stresses pose a great threat to wheat production over the globe. Fungal diseases such as rusts, mildew, along with pests like aphid, hinder the potential yield performance of the elite wheat cultivars to a huge extent. The complex nature of plant-parasite interactions is shown to be the decisive factor for the ultimate resistance expression in wheat. However, the advancement of molecular genetics and biotechnology enabled the replacement of the tedious, time and resource consuming cytogenetic analyses of locating APR and ASR genes using molecular mapping techniques. Continuous efforts have been made to mine resistance genes from diverse genetic resources such as wild relatives for combating these diseases and pests, which are repositories of R genes. Additionally, they offer a promising source of genetic variation to be introgressed and exploited for imparting biotic stress tolerance in cultivated wheat. Though just a handful of R-genes are cloned and molecularly characterized in wheat so far, more than 350 resistance genes for various diseases have been identified and successfully introgressed into elite varieties around the globe. Modern genomics and phenomic approaches coupled with next-generation sequencing techniques have facilitated the fine-mapping as well as marker aided selection of resistance genes for biotic stress resistance wheat breeding.

Abstract:
Suspension system of a vehicle is used to minimize the effect of different road disturbances for ride comfort and improvement of vehicle control. A passive suspension system responds only to the deflection of the strut. The main objective of this work is to design an efficient active suspension control for a full car model with 8-Degrees Of Freedom (DOF) using adaptive soft-computing technique. So, in this study, an Adaptive Neuro-Fuzzy based Sliding Mode Control (ANFSMC) strategy is used for full car active suspension control to improve the ride comfort and vehicle stability. The detailed mathematical model of ANFSMC has been developed and successfully applied to a full car model. The robustness of the presented ANFSMC has been proved on the basis of different performance indices. The analysis of MATLAB/SMULINK based simulation results reveals that the proposed ANFSMC has better ride comfort and vehicle handling as compared to Adaptive PID (APID), Adaptive Mamdani Fuzzy Logic (AMFL), passive, and semi-active suspension systems. The performance of the active suspension has been optimized in terms of displacement of seat, heave, pitch, and roll.

The virulence of the species of the entomopathogenic fungi Lecanicillium psalliotae (strain Vl 78), L. dimorphum (Vl 79) and L. pissodis (ARSEF 8057) against bean aphid Megoura viciae Buckt and greenhouse whitefly Trialeurodes vaporariorum Westwood has been compared with the virulence of well-studied species L. muscarium (Vl 21, Vl 72), L. lecanii (Vl 5), L. longisporum (Vl 13). Species L. longisporum (Vl 13), L. muscarium (Vl 72), L. psalliotae (Vl 78) had a virulence of more than 80% against bean aphid, other strains showed the virulence less than 60%. All strains except L. longisporum (Vl 13) had a high virulence about 75–100% against the greenhouse whitefly. As appeared, the species L. psalliotae (Vl 78) has the perspectives against the both insect species. Its virulence corresponds to the similar level of mortality caused by the well-studied species L. muscarium.

Abstract:
Considering the growing demand for organic production of food and registration-related problems, the number of pest management products that can be used in this sort of production is limited. In this study the efforts have been made to formulate the Neem oil emulsions which would be used as agrochemicals. Bioassays were performed on aphids (Myzodes persicae Sulz., Aphis gossypii Glow , Aphis pomi Deg.) in order to compare the insecticidal activity of the neem oil new preparative form NEEM-01 with that of the commercial biorational product Pelecol EO. The bioassays conducted on the aphids demonstrated that the NEEM-01 aplicated at the doze 8,0 l/ha was not effective as the commercial product Pelecol EO. But at the doze 10,0 l/ha new preparative form of neem oil has demonstrated a good biological effectiveness during 7 days after two treatments.

Abstract:
Climate change is becoming increasingly unpredictable as the climate dries up, protected areas grown with vegetables are growing every day, but farmers in this area are facing a number of problems, including pests of green cucumber lice (Aphis gossypii), the common thrips. (Thrips tabaci), the common red spider (Tetranychus urticae). Scientists around the world are conducting studies to propose solutions. The use of material that allows the passage of a larger amount of UV rays inhibits the development of aphid colonies. The dual application of Lecanicillium longisporum for the simultaneous suppression of green lice of cucumbers and powdery mildew has been demonstrated. Beauveria bassiana preparations are highly effective against tripe. For a future assured with high quality vegetables, it is necessary to develop as diverse methods as possible to control pests, so that each farmer can choose the method that suits him, both technologically and economically. The methods should be applicable in the most diverse areas of the earth. We must learn to model not only favorable climatic conditions but to create a healthy and viable ecosystem, so the greenhouses will generate profit for the farmer, fresh and tasty products for us.

Abstract:
Since APHIS was formed in 1972, it has evolved into a multi-faceted Agency with responsibilities that include protecting and promoting U.S. agricultural health from foreign pests and diseases, regulating genetically engineered organisms, administering the Animal Welfare Act, and carrying out wildlife damage management activities. It has been 15 years since APHIS compiled a history of its mission and activities. This year, 2012, marks both the 40th anniversary of the Agency and the 150th anniversary of USDA, providing a unique opportunity to put that history in context. This retrospective briefly examines the history of animal and plant health regulation within USDA, assesses APHIS' development over four decades, includes biographies of the Agency’s Administrators, and provides snapshots of some of the milestone issues and events that define the Agency’s history and its accomplishments.
