ABSTRACT      Developmental period, sex ratio, and pupal weights of F progenies of C. auricilius showed no significant variations in larval, pupal, and hatching to emergence times between the 2 sexes of the insect. Goodness-of-fit test showed that the population conforms with the 1:1 sex ratio. Analysis of variance for pupal weights showed female pupae are significantly heavier than the males. Assessment of the effect of crystal protein Cry1A c on mortality and behavior of C. auriculus indicated mortality was directly correlated with higher concentrations but not on the choice tests. DIPEL, Margosan-O , and azadirachtin affected the growth and development of the larvae. It was observed that larvae avoided adulterated diets, a behavior that should be considered in the proper applications of biocides.
