Abstract

Relationship between temperature and developmental rate of different stages of Habrobracon hebetor Say (Hym.: Braconidae) were studied at 10 constant temperatures (16-38 °C). Development time for different stages of the parasitoid was obtained. Seven non-linear models describing the effect of temperatures on developmental rate were fitted to the observed data. Our statistical analysis indicated that the models, Logan 1 and Stinner were fitted well to all stages of Habrobracon hebetor (as indicated by r2 values). In this research, equations for above mentioned models referring to different developmental stages of the parasitoid have also been given.
