Integrated pest management, in which the conventional pesticides are augmented by one or more nonchemical control practices, has been receiving renewed interest. What is new in this revitalization of an old technique is the careful and more knowledgeable application of a variety of control techniques.

Eradication is the elimination of every single individual of a species from an area to which recolonization is unlikely to occur. Cost-benefit analyses of eradication programs involve biases that tend to underestimate the costs and overestimate the benefits. In this review, we (a) highlight limitations of current cost-benefit analyses, (b) assess eradication strategies from biological and socio...

Baseline susceptibility to abamectin in thirty-four Colorado potato beetle (CPB) populations was determined by diet-incorporated assays. Also, filter-paper exposure assays quantified esfenvalerate and azinphosmethyl resistance. LC50 values ranged from 0.09 to 2.69 ppm abamectin and differed by 9fold in 1993 and 21-fold in 1994. Based on the composite response of this assay, the predicted LC50, ...

Research and development on IPM was initiated in Pakistan in the 70’s. However, efforts to implement IPM at the farm level did not bear fruit. A major obstacle has been the mindset at the policy level to increase crop production to feed the ever-increasing population. Pesticides became a major instrument of increasing production leading to ‘pesticide treadmill’ situation. Although IPM-FFS “Veha...

The tools of insect pest management include host plant resistance, biological control, and insecticides and how they are integrated will influence the durability of each. We created a detailed model of the population dynamics and population genetics of the diamondback moth, Plutella xylostella L., and its parasitoid, Diadegma insulare (Cresson), to study long-term pest management in broccoli Br...

Tyrosine phosphorylation is implicated in regulating the adherens junction protein, p120 catenin (p120), however, the mechanisms are not well defined. Here, we show, using substrate trapping, that p120 is a direct target of the protein tyrosine phosphatase, PTP-PEST, in epithelial cells. Stable shRNA knockdown of PTP-PEST in colon carcinoma cells results in an increased cytosolic pool of p120 c...
