Abstract

The pod borer, Helicoverpa armigera is considered to be the most important pest of several crops such as cotton, tomato,tobacco, chick pea, pigeon pea etc. Trichogramma chilonis, the tiny wasp, which are the major parasitoids of lepidopteraneggs are used to control plant pests and are used widely in augmentative biological control. In the present laboratory study,infestation capacity of the parasitoid on the eggs of H. armigera was undertaken at Mysore, India. Also, the hatchabilityrate, developmental period and longevity of the biocontrol agent were studied. The results revealed that the T. chilonisexhibited 58.54% parasitization and 93% hatchability on the pod borer. It took an average of 8.28 days to develop underlaboratory conditions and lived for 6.7 days. These findings will be helpful in employing T. chilonis in the control of H.armigera on the agricultural crops in the field.
