ABSTRACT

The effect of different host diets on the Intrinsic rate of natural Increase (rm) of Bracon hebetor was observed and
calculated. The experiments were conducted by supplying host with four types of natural diets. All experiments related to the
effect of diets were conducted at 27±2oC, 70% relative humidity and 12h L:D photoperiod. The fecundity, innate capacity of
increase in number and intrinsic rate of natural increase were highest when host larvae were reared on wheat when
compared to maize, jowar and rice. The doubling time (DT) was shorter on wheat than maize, jowar and rice showing an
inverse ratio to rm and rw. On the basis of life table statistics of Bracon hebetor, wheat and maize are the most suitable
diets of its host Corcyra cephalonica
