研究结果表明：①３龄全龄（共８０ｈ）与４龄入眠前８ｈ至５龄起蚕（共４８ｈ）两期的家蚕熏蒸试验，丙硫磷、甲丙硫磷对家蚕无明显毒性，家蚕均能正常取食、生长、蜕皮、入眠、上簇结茧；②对２龄蚕连续饲浸药叶２４ｈ，丙硫磷、甲丙硫磷（８０ｍｇ／Ｌ）处理区仅有１．１１％～９．６７％的家蚕死亡；对５龄蚕连续饲喂浸药叶１２ｈ，丙硫磷以１６０ｍｇ／Ｌ、甲丙硫磷以８００ｍｇ／Ｌ对家蚕安全，上簇率为１００％；试验表明，丙硫磷、甲丙硫磷可在蚕桑区使用，但应避免药剂与桑叶直接接触。 The results showed that: (1) There was no significant toxicity to silkworm in both the 3-age full-age (80h) and 4-instar 8h to 5-instar silkworm (48h) Can feed, grow, molt, sleep, and cluster on the cocoon. (2) For the second instar larvae fed on the leaves continuously for 24 h, the areas treated with cefotaxime and metsulfuron-methyl (80 mg / L) 9.67% of the silkworms died. The fifth instar silkworm was fed with the leaves continuously for 12h, and the concentrations of acetosulfan at 160mg / L and cefotaxime at 800mg / L were 100% Cefotaxime, metothiun can be used in the sericulture area, but should avoid direct contact with agents and mulberry leaves.
