Pot experiments carried out to study the efficacy of nucleopolyhedrovirus against the Bihar hairy caterpillar Spilarctia obliqua (Walker), at Bangalore indicated that a spray of NPV @ 1×107 POB ml−1 resulted in a larval mortality of 93.33% in third instar larvae and 87.5% in fourth instar larvae. Cent per cent larval mortality was obtained when the plants were sprayed with dichlorvos @ 2 ml l−1. The leaf damage for viral treatments varied from 19.65 to 41.89 and 21.0 to 38.0 per cent for third and fourth instar larvae, respectively.Keywords

Field experiments at Pavagada, Karnataka during August 2003, indicated that Amsacta albistriga NPV @ 1.5 x 1012 POB/ha was as effective as chlorpyriphos @ 20g a. i./ha against red hairy caterpillar. For an environmentally friendly approach AaNPV can be used as an effective component of IPM packages for the control of red hairy caterpillars in the endemic areas of Karnataka.Keywords
