Effects of 53D1 on B. mori growth and development.

Doses of 53D1 (Utot/cm2 diet)	Larval mortality (%)	Duration of larval stage (days)	Maximal larval weight before pupation (g)	Pupal weight at day 8 (g)	Cocoon weight at day 8 (g)
0 (control)	2.78 ± 2.78	24.83 ± 0.21	3.32 ± 0.09	1.06 ± 0.04	0.24 ± 0.01
6	61.11 ± 2.78∗	31.69 ± 1.37∗	2.14 ± 0.15∗	0.80 ± 0.06∗	0.13 ± 0.01∗

Each value represents the mean ± standard error of three independent experiments. Each experimental group was composed of 12 larvae. Larvae mortality is reported as the percentage of the initial number of larvae. ^∗p < 0.001 versus control, Student’s t-test.
