Abstract:
Laboratory experiments were conducted at Department of Agricultural Entomology, VNMKV, Parbhani during 2020-2021 to study the biology of green lacewing, Chrysoperla zastrowi sillemi (Esben-Petersen) on unsterilized and sterilized eggs of Corcyra cephalonica, Aphis craccivora, Aphis gossypii, Brevicoryne brassicae and Uroleucon compositae. This study was observed under different biological parameters. Incubation period of Chrysoperla sp. ranged from 3.84 to 4.41 days on different preys while egg hatching percentage recorded highest when reared on Corcyra cephalonica with 94.77 per cent. Larval and pupal period were minimum with 9.00 and 5.43 days on unsterilized eggs of Corcyra cephalonica. Oviposition period and fecundity were highest on unsterilized eggs with 29.57 days and 371.6 eggs, respectively. These results revealed that unsterilized eggs of Corcyra cephalonica was most suitable host for mass multiplication of the predator in the laboratory.
