abstract
The experiment was conducted in The Biological Control Laboratory, Department of Entomology, College of Agriculture, Indira Gandhi Krishi Vishwavidyalaya, Raipur (C.G.). The purpose of this research was to determine the effect of the difference in parasitization of Corcyra larvae reared under different diets by ecto-parasitoid Bracon sp. In experiment framed to see the difference in parasitization of Corcura cephalonica larvae by Bracon sp., five larvae were selected and reared from thirteen different diet treatments and covered using separate small petridishes (plate). Number of eggs laid on the larvae varied significantly and was highest in T11 (rice+jowar+maize) (37.33 eggs/ 5 larvae) and minimum in T1 (rice) (2.67 eggs/ 5 larvae).Similarly the number of pupae of Bracon sp. were highest again in T11 (rice+jowar+maize) (31.33 pupae/ 5larvae and least in T1 (rice) (1.67 pupae/ 5 larvae). Highest number of male Bracon were seen on T5 (maize) (4.67) on T1 (rice) (0.33), where as highest number of female emergence was observed in T4 (sorghum) (21.00) and lowest on T1 (rice) (0.67).
