摘要
新疆第一代棉铃虫成虫发生期间,用2种有机酸和4种杀虫剂处理杨枝把,研究棉田诱集棉铃虫效果。试验结果表明:有机酸处理后的杨枝把诱集数量明显比对照多,其中前3d平均诱集数量比对照多43 9%,6d后总计多26 8%。喷洒杀虫剂的杨枝把诱蛾效果差异较大,拉维因和赛丹的诱蛾量与清水对照差异不明显,但死亡率显著提高。保得和功夫处理杨枝把的诱虫效果较低。
Field studies on the trapping Helicoverpa armigera moth wi th poplar branch bundles treated with 2 organic acids and 4 insecticides. The r esults showed that the organic acids treated bundles attracted 43.9% more moth t han the check in the 1st 3 d and 26.8% in 6 d. No marked difference in number o f moth attracted between Thiodicarb (Larvin), Thiodan and the check, but 53.0%-7 7.3% of the moth were killed in the insecticide treated bundles and no dead moth was found in the check. Cyhalothrin and the Bull dock treated bundles were not attractive to the moth.
