摘要： 为减少蜻蜓稚虫对池塘养殖的危害，选用敌百虫、联苯菊酯、噻虫胺3种农药分别对灰蜻终龄稚虫进行急性毒性试验。结果表明：3种农药对灰蜻终龄稚虫的LC50(96 h)值分别为0.2506、0.0012和0.0517 mg a.i./L。对比3种农药对灰蜻终龄稚虫、已知的淡水鱼类及美国牛蛙蝌蚪的LC50(96 h)值，以及3种农药的水生生态特征，显示噻虫胺是防治蜻蜓稚虫对池塘养殖危害较好的农药。

Abstract: To select efficient and safe pesticides and control dragonfly larvae in fishing ponds, acute toxicity tests of three pesticides (trichlorfon, bifenthrin and clothianidin) to last-stadium larvae of Orthetrum were performed respectively. The results showed that LC50 (96 h) values of trichlorfon, bifenthrin and clothianidin to last-stadium larvae of Orthetrum were 0.2506, 0.0012 and 0.0517 mg a.i./L, respectively. Comparing LC50 (96 h) values of the three pesticides to the last-stadium larvae of Orthetrum, freshwater fishes and the tadpole of Rana grylio, and the aquatic ecological characteristics of the three pesticides, clothianidin was recommended as the suitable pesticide for controlling dragonfly larvae in fishing ponds.
