Abstract:
Studies on the host preference of green lace wing, Chrysoperla zastrowi sillemi (Esben-Petersen) (Chrysopidae: Neuroptera) fed on various hosts was conducted at the Bio-control Laboratory, IGKV, Raipur, Chhattisgarh during 2020-2021 and 2021-2022. Larval stages of C. zastrowi sillemiwere evaluated for its feeding preferences on various hosts and results revealed C. zastrowi sillemias one of the best biological control agent for predating lepidopteran eggs and sucking pests. Result revealed that maximum host preference of 1^st instar larvae (grub) was recorded for eggs of C. cephalonica (24.00 percent) and minimum in case of C. cirripediformis i.e. (10.00 percent). Maximum host preference of 2^nd and 3^rd instar larvae (grub) was recorded in L. erysimi (21.50 percent) and (24.00 percent) with a minimum in case of C. cirripediformis i.e. (12.50 percent) and (10.00 percent).
