Effect of Pyriproxyfen on Orthaga Exvinacea Hampson (Lepidoptera: Pyralidae)

Abstract

Pyriproxyfen is an important Insect Growth Regulator (IGR) mimicking Juvenile hormone. IGRs are usually used to control insect pests in Integrated Pest Management (IPM) Programme. In the present study topical application of Pyriproxyfen produced irregular moulting, dark cuticle, shrinkage of the body and mortality in the larvae of Orthaga exvinacea. When the larvae were fed with Pyriproxyfen treated mango leaves, they showed feeding inhibition and weight reduction.
