The results showed that the female silkworm moth powder could reduce MDA content in mouse serum and liver obviously. In high dosage group (8 g/kg), MDA content was lowered to the level of normal control group. Moreover, female silkworm moth powder could increase activities of SOD and GSH-Px in serum and liver of the model mice. The increases in middle dosage group (4 g/kg) and high dosage group reached extremely significant level.

The test results of acute toxicity were examined with Pearson's degree of fitting. The results indicated that the silkworm was extremely sensitive to Chlorantraniliprole. The median lethal concentration (LC50) was 4.0905×10^(-3) mg/L and median lethal dose (LD50) was 1.1435×10^(-8) mg/larva for the 3rd instar newly exuviated larvae. No toxicity was observed when normal concentrations of Chlorantraniliprole were used to fumigate the silkworm rearing room. Both irrigation and leaf spraying with 1.25×10^(-4) mg/L Chlorantraniliprole solution showed strong systemic transmission properties in root, leaf and whole plant. The residual toxic period of this insecticide to silkworm was very long. Mulberry leaves sprayed with 1.25×10^(-4) mg/L Chlorantraniliprole solution could still cause 100% mortality of the 3 and 5 instar larvae after 60 d. Furthermore, toxic reaction was very quick. The poisoning symptoms emerged within 1~5 h after feeding on the poisonous leaves. The poisoned larvae experienced such symptoms as stopping ingestion, remaining still, vomiting slightly and body atrophy sequentially, and died ultimately.
