Table 2. Statistical analysis of labial salivary glands soluble protein and glucose oxidase (GOX) activity.

Caterpillars were transferred from plant to artificial diet and allowed to feed for specified times. Times were staggered to ensure that caterpillars were approximately the same developmental age when the labial salivary glands were removed and assayed. Differences in protein and enzyme activity were analyzed by 1-way ANOVA followed by a Tukey post-hoc test. Significant differences are shown in Fig. 2.
