Insect pests are a major cause of crop loss globally. Pest management will be effective and efficient if we can predict the occurrence of peak activities of a given pest. Research efforts are going on to understand the pest dynamics by applying analytical and other techniques on pest surveillance data sets. In this study we make an effort to understand pest population dynamics using Neural Netw...

Five herbivorous introduced mammals are sympatric in the central Southern Alps. All of these species have the potential to affect conservation values, yet the Department of Conservation at present monitors and mitigates the impacts of only one. We outline ecological arguments for multi-species management of sympatric herbivore pest impacts and use the two-species system of sympatric thar and ch...

the leopard moth, zeuzera pyrina (l.) (lepidoptera: cossidae) is a serious pest of walnut and apple trees in iran. one of the control methods for this pest is the mass trapping of males using pheromone traps. to determine the best size and color of traps, four different colors (green, yellow, white, gray) and two different sizes (delta shape with standard adhesive surface, 19 × 22 cm and trapez...

Invertebrate pest invasions and outbreaks are associated with high social, economic, and ecological costs, and their significance will intensify with an increasing pressure on agricultural productivity as a result of human population growth and climate change. New molecular genetic and genomic techniques are available and accessible, but have been grossly underutilized in studies of invertebrat...

The cytoplasmic protein tyrosine phosphatase, PTP-PEST, associates with the focal adhesion proteins p130cas and paxillin and has recently been implicated in cell migration. In this study, we investigated the mechanism by which PTP-PEST regulates this phenomenon. We find that PTP-PEST is activated in an adhesion-dependent manner and localizes to the tips of membrane protrusions in spreading fibr...

Area-wide pest management is one of several major plans or strategies for coping with pest problems. Management of localized populations is the conventional or most widely used strategy, wherein individual producers, other operators and households practice independent pest control. However, since individual producers or households are not capable of adequately meeting the challenge of certain v...

the study was conducted among the two farmer groups in bhaktapur and kavre districts of nepal. the main objective of the study is to evaluate the differences in belief, attitude and practices felt by the farmers after participation in the ipm ffs. the study has been based on data collected through personal interview with the farmers, focus group discussion, personal observation in the farmers f...

Phenotypic expression of different genes controlling resistance to tobacco mosaic virus (TMV) in tomato was analysed in the protoplast system using otherwise isogenic breeding lines. Genes Tm-2 and Tin-22 were not expressed and did not prevent TMV-L, a common tomato strain of TMV, infecting and multiplying. By contrast, homozygous gene Tin-I was able to express its effect in protoplasts as well...

Pest index, a new approach to categorizing the threat posed by an organism to woody plants, is proposed to assist plant managers in establishing treatment thresholds for pests of woody plants. The need for such a tool is based on the incredible diversity of pests of woody plants and the lack of experimental data establishing such thresholds. The pest index is computed using information about th...
