Abstract

The present study indicated that the parasitized eggs of C. cephalonica stored at 10°C showed decreasing trend of parasitoid emergence with the increase in storage period. It reached 30.25% from 81.25% after 30 days of storage. The parasitization efficacy of adults Trichogrammatids also decreased with the increase in storage period, which reached 52.25 percent from 79.50 percent after 10 days. Wherein, Tricho-cards can be stored for 10 days at 10°C without significant reduction in the emergence and parasitization efficacy of Trichogrammatids female.
