Abstract:
Bracon hebetor (Say) is a cosmopolitan idiobiont braconid that parasitizes several lepidopteran larvae including Helicoverpa armigera. Parasitoids have always shown their preference towards a particular host species and in this aspect, the diet of the host also plays an important role. Likewise, the development and growth-related parameters of parasitoids developing on hosts fed on different diets also vary. The present studies were taken up during 2019, at the Biological control laboratory, Indira Gandhi Krishi Vishwavidyalaya, Raipur, Chhattisgarh. to study the morphometric variations of different immature and adult stages of B. hebetor reared on the larva of Helicoverpa armigera fed on various host plants.
