| Abstract: | 400, 800, 1200 and 1600-fold of "Wanling" pesticide were respectively sprayed on the mulberry trees, and water was kept as a control. The symptom of poisoned silkworm and the residual lives of different concentrations of this pesticide were all determined by feeding them with treated leaves. It is important that leaves should be picked 2 weeks after spraying in order to ensure the safety of silkworm rearing |
