Figure 5. Effect of diet on the percent of non-feeding CPB males and females. Symbols and methods as in the legends to Figures 2 and 3. For each experiment, each treatment group contained between 50 and 75 beetles (except for the Lettuce group which contained between 25 and 50 individual insects), and each experiment was performed at least two times. Therefore, each value represents the mean of at least two separate determinations. To ascertain if the sex of the beetle significantly affected the percent of non-feeding adults, Student's t-Tests (P<0.05) were performed. * indicates treatment groups in which there was a significant difference between males and females. A one-way ANOVA followed by the Tukey's HSD post-hoc test was used to determine if there were significant differences among treatment groups for males, and separately for females. For any given diet, means ( S. E.) followed by the same letter (lower case for females; upper case for males) were not significantly different.
