Abstract
Laboratory experiments were conducted to study the survival of different larval instars of Chrysoperla carnea in Petri plates without any food. Survival percentage was highest (96.00%) after 24 hours of starvation in 2nd instars, followed by 93.00% in 3rd instars. After 72 hours, survival percentage was 8.50, 70.00 and 69.50% in 1st, 2nd and 3rd instars, respectively. Survival decreased with increase in time of starvation. Survival percentage remained 0.00% after 164 hours for 1st and 2nd instars, whereas 6.25% survival was recorded in 3rd instars.
