| 摘 要： | 用7种药剂对蔬菜上朱砂叶螨的室内毒力和田间药效进行测定。结果表明:7种药剂中杀螨活性最高的是抗生素类-阿维菌素和甲氨基阿维菌素苯甲酸盐,24h时LC50分别为0.1300和0.7118mg/L;唑螨酯和哒螨灵的效果次之,LC50分别为1.4808和3.1586mg/L;螺螨酯的敏感性最低,24h时LC50为1 181.4348mg/L;田间试验结果表明:1.8%阿维菌素乳油、1%甲氨基阿维菌素苯甲酸盐乳油和15%哒螨灵乳油对朱砂叶螨的防效都非常好,2d的防效均达98%以上,14d的防效为100%。40%炔螨特乳油和5%唑螨酯悬浮剂在药后7和14d的防效达99%以上;240g/L螺螨酯悬浮剂表现出速效性稍低,持效性良好,药后14d防效为99.94%。

| Abstract: | The toxicity and field control efficacy of seven acaricides to the adult of carmine spider mite Tetranychus cinnabarinus were studied.The results showed that abamectin and emamectin benzoate had the highest toxicity among all the tested acaricides,with a LC50 value of 0.1300 mg/L and 0.7118 mg/L,respectively.Fenpyroximate and pyridaben showed relative low toxicity,with a LC50 value of 1.4808 mg/L and 3.1586 mg/L.Propargite showed lowest toxicity,with a LC50 of 356.1753 mg/L.The results of field efficacy test showed that the abamectin 1.8% EC,emamectin benzoate 1% EC and pyridaben 15% EC showed excellent efficacy,the control efficacy of 2 days was up to 98%,and 14 days was 100%.The control efficacy of 7 days and 14 days of propargite 40% EC and fenpyroximate 5% SC were up to 99%.240 g/L Spirodiclofen exhibit long persistence with a control efficacy of 99.94% in 14 days. |
