| Abstract: | It was found out in the present study that Diaphania perspectalis (Walker) ,an important leaf-eating insect attacking Buxus microphylla sitbetzua var.suffruticosa(mikino),had five generations inNanchong and it hibernated in the form of its third instar larvae. Most larvae had six instar stages inall the five generations with a few having seven instar stages. Adult insects showed weak phototaxisand bisexual reproduction. Nutrients had to be repenished before they laid eggs,Most of the eggswere clustered to form a mass. Manual clearing of their hibernating larvae and the frist generationlarvae and pupae could provide an effective control of the pest. |
