Biologicalcontrol with Egg Parasitoids

The egg parasitoids particularly Trichogramma spp. have undoubtedly had a significant role in boosting the status of biological control of crop pests.

Though Trichogramma is extensively used in many countries; sound knowledge of the egg parasitoids is urgently needed as rightly pointed out by the editors in the preface.
