Abstract:
Laboratory experiments were conducted at Department of Agricultural Entomology, VNMKV, Parbhani during 2020-2021 to study feeding potential of green lacewing, Chrysoperla zastrowisillemi (Esben-Petersen) on Unsterilized and sterilized eggs of Corcyra cephalonica, Aphis craccivora, Aphis gossypii, Brevicoryne brassicae and Uroleucon compositae. Consumption capacity of first, second and third instar larvae revealed that highest consumption was noticed for sterilized eggs of Corcyra cephalonica with 47.69, 102.45 and 196.52 eggs, respectively and total consumption observed was 346.66 eggs in a developmental period of 9.46 days whereas, feeding capacity on different hosts ranged from 311.95 eggs to 169.57 aphids. These results unfold that eggs of Corcyra cephalonica are found to be most suitable for laboratory rearing of the predator, Chrysoperla zastrowisillemi.
