| 摘 要： | 氯虫苯甲酰胺(Chlorantraniliprole)独特的杀虫原理和优良的杀虫效果使其迅速成为大田作物害虫防治的主要药剂之一。采用食下、内吸和熏蒸等方法,并通过田间试验,研究了氯虫苯甲酰胺对家蚕的毒性效应。食下毒力试验结果经Pearson拟合度检验表明,氯虫苯甲酰胺对3龄起蚕的食下致死中浓度(LC50)为4.090 5×10-3mg/L,致死中量(LD50)为1.143 5×10-8mg/头;药剂在常规浓度下对家蚕无熏蒸毒性;1.25×10-4mg/L稀释药液对桑树根灌和喷叶处理,表现极强的根部、叶部和全株性内吸传导特性;药液对家蚕的残毒期很长,1.25×10-4mg/L稀释药液田间喷雾桑叶,间隔60 d后采叶饲喂3龄和5龄蚕的死亡率均为100%,且中毒反应极快,添食毒叶后1～5 h出现中毒症状,经停止食桑、静伏、少量吐液、蚕体萎缩等过程后陆续死亡。根据试验结果建议农药管理部门尽快采取措施,确保该杀虫剂在防治其它农作物害虫时,减少对养蚕业的影响,蚕区最好禁用该杀虫剂。

| Abstract: | Owing to its unique insecticidal principle and excellent insecticidal effect,Chlorantraniliprole has been quickly adopted as one of the major insecticides for pest control of field crops.In present study,the toxicity of Chlorantraniliprole to silkworm(Bombyx mori) was investigated by means of feeding,systemic toxicity,and fumigation in combination with field experiments.The test results of acute toxicity were examined with Pearson's degree of fitting.The results indicated that the silkworm was extremely sen... |
