Evaluation of larval body weight of H. vigintioctopunctata 48 h after ingestion of C. glutamicum cells sterilized by alcohol or heating. Sample 1, larvae fed water (negative control); 2, 4, 6, larvae fed C. glutamicum 2256LΔrnc cells harboring pVC7H2 vector; 3, 5, 7, larvae fed C. glutamicum 2256LΔrnc cells harboring pVH2-HvIap-1. The data are presented as the mean ± SD. For each group, 4–5 larvae were used. Asterisks indicate significant differences (P < 0.05) from corresponding values for the strain harboring only vector
