乙酰甲胺磷对家蚕3龄起蚕的急性食下毒性(LC50)为41.80 mg/L,中等毒性;在常规使用浓度下对家蚕无熏蒸毒性。用30%乙酰甲胺磷EC 300倍、600倍和1200倍稀释液对桑树进行局部喷叶或根灌处理,喷药桑叶对3龄起蚕无中毒死亡的间隔时间为30 d、25 d和25 d,在桑叶上的残毒期中等偏长;未直接喷药的桑叶可使家蚕出现不同程度的中毒死亡,表明乙酰甲胺磷可通过桑叶、桑根内吸传导至上部桑叶。结果表明,乙酰甲胺磷用于防治桑园害虫应注意掌握安全间隔时间。
乙酰甲胺燐對傢蠶3齡起蠶的急性食下毒性(LC50)為41.80 mg/L,中等毒性;在常規使用濃度下對傢蠶無熏蒸毒性。用30%乙酰甲胺燐EC 300倍、600倍和1200倍稀釋液對桑樹進行跼部噴葉或根灌處理,噴藥桑葉對3齡起蠶無中毒死亡的間隔時間為30 d、25 d和25 d,在桑葉上的殘毒期中等偏長;未直接噴藥的桑葉可使傢蠶齣現不同程度的中毒死亡,錶明乙酰甲胺燐可通過桑葉、桑根內吸傳導至上部桑葉。結果錶明,乙酰甲胺燐用于防治桑園害蟲應註意掌握安全間隔時間。

The LC50 of Acephate on Silkworm of 3 instar was 41.80 mg/L, which indicated moderate toxicity. However, it was non-toxic on silkworm in the conventional concentration. The 30% Acephate was diluted by 300, 600, 1200 times separately, and the dilutions were sprayed on the leaves or irrigated on the roots. The time intervals of no toxic death were 30 d, 25 d and 25 d separately when the dilutions were sprayed on the leaves. And there were also dfferent de?grees of poisoning death of silkworm when the dilutions were irrigated on the roots, which means Acephate could be transferred to the leaves. The results indicated that the safe interval time should be paid attention when Acephate was used to control mulberry pests.
