Larva feeding on lower side of the leaves, this is an unusual situation in infestations. One side feeding (left side in image) is a normal habit of this pest.

The gypsy moth, Lymantria spp. (Lepidoptera: Lymantriidae), is one of the distinguished pest species feeding on forest trees and the caterpillars prefer oaks, birches, poplars and willows, causing huge defoliation, growth loss and tree mortality. Softwoods like hemlocks and pines are more likely to die after a single defoliation than hardwoods. A n...

Green lacewing Chrysoperla nipponensis (Neuroptera: Chrysopidae) is an important predator, its larvae are considered as generalist beneficials. To increase the efficiency of the larvae for mass rearing of this predator, an artificial diet was standardized. A functional response study of 3rd instar Chrysoperla nipponensis (Neuroptera: Chrysopidae) larvae reared on artificial diet and Corcyra cephalonica eggs was carried out. Multiple prey densities of aphid, Aphis craccivora, papaya mealybug, Paracoccus marginatus and whitefly, Bemisia tabaci were employed. The larvae of C. nipponensis showed type II functional response to all prey species. The highest finding ranges (a) of larvae reared on artificial diet and C. cephalonica eggs were of 0.681 and 0.393 on mealybug and whitefly, respectively. Both, C. cephalonica eggs and artificial diet reared larvae showed maximum and minimum handling time on aphid (2.129 and 2.045) and mealybug (0.461 and 0.413), respectively. The highest and lowest predation capacity of artificial diet and C. cephalonica eggs reared larvae was registered on aphids (0.479 and 0.461) and mealybug (2.433 and 2.177) respectively.
