Figure 4. Effect of diet on percent mortality of various stages of the CPB. Symbols, methods and statistical analysis as in the legend to Figure 2. For a given experiment, percent mortality was determined for each stage by dividing the number of fatalities observed for a given stage by the total number of beetles that were placed on diet at the beginning of the experiment. Adult mortality was determined through day 9 post emergence. For each treatment group, total mortality equals the sum of the mortalities at each stage. Values represent the mean of three experiments.
