Caption: Photograph of Trichogramma evanescens, a female chalcid wasp, laying her eggs in those of the cabbage moth, Mamestra brassicae. The female pierces the egg of the cabbage moth, depositing her brood, which once hatched (larvae) feed on & destroy the host egg. Cabbage moths lay their eggs in the foliage of the cabbage plant. Once hatched the larvae feed destructively on the leaves & heart of the crop. The parasitizing habits of Trichogramma have been employed in biological pest control experiments & the wasps reared commercially in the USA to eliminate specific crop pests. This species, T.evanescens has been used extensively in China to control crop pests.
