Jaiswal, A.K., Sharma, K.K., & Agarwal, S.C. 1999 A modified and upgraded device of insect-separation for managing the insect pests of lac.. National Academy Science Letters-India 22(5-6): 106-110.

Notes: An indigenous device for automatic separation of predators, parasitoids of lac insects, and parasitoids of lac predators was modified and upgraded. This upgraded version retrieves more parasitoids of lac predators than earlier 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, Brachymeria tachardiae, Elasmus claripennis and Pristomerus sulci while in case of Bracon greeni and Apanteles tachardiae it could do so to the extent of 82% and 96% respectively. These species therefore, could be released in nature to augment their natural population and check predators of lac insect, Kerria lacca.
