Abstract

Developmental period, sex ratio, and pupal weights of F1 progenies of C. auricilius were investigated. No significant variations in larval, pupal, and hatching to emergence times were observed between the two 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. 

The effect of crystal protein Cry1A c on mortality and behavior of C. auricilius was assessed using no-choice and choice tests. 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.
