Figure 3. Effect of stage of removal on percent egg hatch of eggs laid by adults that had emerged from experimental and control groups of whitefly nymphs. A brief description of the methods used for mating adult control and experimental whiteflies is provided in the legend for Fig. 2. For T. vaporariorum and B. tabaci, respectively, each value represents the mean ± S.E. of 14–17 and 8–14 separate replicates/mated pairs; each replicate was based on an examination of 80–100 eggs. A one-way ANOVA (α = 0.05) was used to determine if there were significant differences among control and experimental groups for each species of whitefly. Since P was >0.05 when means for control and experimental groups of each species were compared, the Tukey’s comparison of means test was not performed.
