Abstract

The present communication deals with the biological control - ladybird beetle Efficacy against aphids (Chaitophorus spp.)  Fully matured ladybird beetles and aphids were collected from the willow trees. These natural enemies were reared on the aphids for the collection of larvae of ladybird beetles. The results show that there was significant control of Chaitophorus spp by the ladybird beetles. The efficacy of ladybeetle from 1st to 3rd instars against Chaitophorus spp. was tested during the whole experiment. The immature stage of the beetles instars when feed on aphids have more survival rate and grows very fast. So the efficacy of ladybird beetle against the Chaitophorus species is very good. Plants can be saved from the attack of aphid by using the ladybird beetles.
