A modified and upgraded device of insect-separation for managing the insect pests of lac

An indigenous device for automatic separation of predators, parasitoids of lac insects, and parasitoids of lac predators was modified and upgraded. Th is upgraded version retrieves more parasitoids of Iac predators than earlie r device. Scraped lac kept in a container and the side meshed unit made up of plastic pipes retrieve cent per cent parasitoids of lac predators viz., Agathis coryphe Nixon, Brachymeria tachardiae (Cam.) Elasmus claripennis (C am.) and Pristomerus sulci (Mahd. and Kolub.) while in case of Bracon green i Ashm. and Apanteles tachardiae Cam. it could do so to the extent of 82% a nd 96% respectively. These species therefore, could be released in nature t o augment their natural population and check predators of lac insect, Kerri a lacca (Kerr.).
