采用浸叶法测定了5%氟铃脲乳油对家蚕的食下毒性,结果表明:对3龄起蚕添毒处理后,测得3d的LC50为31.2448 mg/L ,16 d的LC50为0.5463 mg/L ,氟铃脲对家蚕的毒性随着持续时间的延长而增强,其毒性效应表现迟缓,且对家蚕具有很强的累积毒性。
採用浸葉法測定瞭5%氟鈴脲乳油對傢蠶的食下毒性,結果錶明:對3齡起蠶添毒處理後,測得3d的LC50為31.2448 mg/L ,16 d的LC50為0.5463 mg/L ,氟鈴脲對傢蠶的毒性隨著持續時間的延長而增彊,其毒性效應錶現遲緩,且對傢蠶具有很彊的纍積毒性。

The leaf dipping method was adopted to determine the toxicity of 5% hexaflumuron against silkworm .The re-sults reveal that the LC50 of the 3rd instar after adding 5% hexaflumuron 3 days was 31 .2448 mg/L ,that of 16 days was 0 .5463 mg/L ,which indicates that the toxicity of hexaflumuron increased with the passage of time ,and the toxic effect appeared slowly ,with a very strong accumulated toxicity against silkworm .
