斜纹夜蛾的诱集及防治研究

Research on the Trapping and Control of Tobacco Caterpillar

为了适时监测斜纹夜蛾的发生动态和选择高效、低毒的杀虫剂,进行了性诱剂诱集成虫和几种杀虫剂防治斜纹夜蛾效果试验。结果表明:筒型性诱捕器诱集斜纹夜蛾成虫比水盆法更有效;攻蛾、锐劲特、菜喜防治斜纹夜蛾低龄幼虫效果好,对斜纹夜蛾高龄幼虫的防治效果,锐劲特和菜喜不及攻蛾,药后3 d攻蛾的防治效果为97.4%,锐劲特和菜喜分别为14.3%和3.4%。

In this paper, the prominent effect of killing tobacco caterpillar infant with SINPV or fipronil or spinnsad was reported.The effect of killing 4 - 5 instars larva of tobacco caterpillar with SINPV was best than fipronil or spinosad, after treatment of 3 d, the mortality of 4 - 5 instars larva of tobacco caterpillar was 97.4%, 14.3% and 3.4%, respectively. Moreover, canister sex-trapping utensil entraping tobacco caterpillar moth was more efficiency than laver sex-trapping utensil and the factors influencing canister sex-trapping utensil entrap were reported.
