The diamondback moth, Plutella xylostella (L.)(Lepidoptera: Plutellidae), is considered as
one of the most difficult pests to control. It has developed resistance not only to synthetic
insecticides but also to Bacillus thuringiensis-based pesticides. We tested the hypothesis
that selection in a P. xylostella population, from Hosur, India, with deltamethrin would give a
broad spectrum of resistance to several insecticides. We also were interested in genetically
classifying resistance to deltamethrin in the selected population and in evaluating whether …
