Notes on the biology, behaviour and biocontrol agents of mango defoliator Cricula trifenestrata (Lepidoptera: Saturniidae).
In laboratory studies, Cricula trifenestrata, a pest of mangoes, required 76-92 days to complete its life cycle, of which the mean larval and pupal periods were 41 and 26 days, resp., at 25°C and 70% RH. Inter- and intra-generation competition of larvae for food, shelter and pupation sites caused either death or a failure to pupate in some of the weaker larvae. Field studies in Bangladesh showed that parasitization of eggs of C. trifenestrata by Telenomus sp. was up to 100% and that of pupae of the saturniid by Brachymeria criculae was 79.71%. A small number of pupae was parasitized by Mesocomys orientalis and Sarcophaga sp.
