摘要: 采用食下毒叶法测定和比较了有机磷农药毒死蜱对14个不同品种家蚕的室内急性毒性,结果表明: 对毒死蜱敏感性较强的家蚕品种有皓月和7532,其96hLC50分别为1842 6和2145 2 mg·L-1;敏感性较弱的蚕品种有春晓、浙蕾、872、限2和871,其96hLC50为2993 7~3347 1 mg·L-1;敏感性弱的蚕品种有秋实、白玉、CA、菁松、JA、芙蓉和湘晖,其96hLC50为3519 0~4566 5 mg·L-1。说明不同品种的家蚕对农药毒死蜱的敏感性不同,其中皓月和7532对毒死蜱最为敏感。

Abstract: Acute toxicities of chlorpyrifos to 14 different hybrids of silkworm (Bombyx mori) were evaluated in the laboratory using the leaf dipping method. Results showed that the 96hLC50 of chlorpyrifos to Haoyue and 7532 were 18426 and 21452 mg·L-1 respectively. While the 96hLC50 of chlorpyrifos to Chunxiao, Zhelei, 872, Xian 2 and 871 were between 29937-33471 mg·L-1 and to Qiushi, Baiyu, CA, Jingsong, JA, Furong and Xianghui were between 3519-45665 mg·L-1, respectively. It is indicated that the toxicities of chlorpyrifos to different hybrids of silkworm were different, and the two hybrids of silkworm Haoyue and 7532 were most sensitive.
