PARASITOIDS ASSOCIATED WITH DIFFERENT STAGES OF CRICULA TRIFENESTRATA HELFER (SATURNIIDAE: LEPIDOPTERA)

Abstract

One egg parasitoid, Telenomus sp., and two pupal parasitoid, Brachyrneria criculae (Khol.) and Pediobius sp. were found to parasitize Cricula trifenestra/a at the Institute of Postgraduate Studies in Agriculture, Salna, Gazipur and its surrounding locations. The pediobius sp. was recorded for the first time in Bangladesh. Natural egg parasitization was ranged from 0-88% with a mean of 41.1% and those for pupae were 25.0-92.8% with a mean of 66.4%. Larval parasitoids were not found. Higher pupal parasitization was caused by B. criculae compared to Pediobius sp. The mean number of parasitoids developed per pupa was 5.7 and 12.7 for B. criculae and Pediobius sp., respectively when attacked singly and 43 and 11.6 when attacked combinedly.
