Of late, frequent application and large scale use of pesticides for control of
pests led to the endangerment of agro-ecosystem. Indiscriminate use of
insecticides resulted in the destruction of parasitoids and predators of the
pests and ultimately led to the resistance of pests to insecticides and insect
resurgence. In the light of these problems, considerable research has been
devoted to the elucidation of the toxic residues in/on consumable produce.
Considering the seriousness insecticidal problems, there is an urgent need for
developing effective economically viable and environmentally safe pest
management system. Exploitation of bioagents, biogesticides, biointensive
integrated pest management and need base use of pesticides have greater role and
scope
