Chrysoperla carnea (Stephens) plays a prominent role in suppressing pest at early stages of cotton crops. It controls the pests of different crops and recommended for biological control programmes against insect pest. The most common species, C. carnea is widely used and studied for its host preference and reproductive and predatory potential on different pest species. However, the information on survival and predatory potential of this predator the requirement of host eggs of Corcyra cephalonica for this species is lacking Intensive cultivation and use of high yielding varieties under the...

The green lacewing, Chrysoperla carnea (Stephens) is a well established and efficient predator in pest management programmes. It has a wide range of prey with enhanced searching capacity and voracious feeding habit.It is active for throughout the year, feeding on various insect pest on different crops. It plays a prominent role in suppressing pest at early stages of cotton crops. It controls the pests of different crops like tomato, potato, cotton etc. and are widely recommended for biological control programmes against insect pest of cotton, sunflower, tobacco and ground nut.

Linseed budfly (Dasyneura lini Barnes) having order Diptera and family Cecidomyidae is only national key pest causing more than 40 per cent yield losses in different parts of the India. Budfly was observed causing considerable damage by maggots initially to leaf bud and then to the flower buds of linseed during winter. About 50 per cent of buds were found infested. The damaged bud failed to open. The corolla of infested flowers gets shriveled and their essential organs look emaciated even of the flower open. Due to their feeding, galls were not produced and there was no pod formation.Use of...

The leaf miner, Liriomyza trifolii is one of the important pests, which caused serious damage to tomato to the extent of 30-40 % Small yellow maggots hatch and feed inside the leaf tissue, leaving long, slender, winding, white tunnels (mines) through the leaf. The leaf wound made by L. trifolii female to the upper surface of leaves for oviposition creates habitats for the infection of pathogens like bacteria and fungi. After hatching, the larvae mined through the leaf tissues and feed on mesophyll of the leaves creating serpentine mines and blotches on the upper surface. The photosynthesis...
