摘　　要：2011～2012连续两年利用性诱剂开展花生田棉铃虫和地老虎的防治试验,并比较不同诱捕高度及诱捕器类型对诱捕效果的影响。结果表明:使用棉铃虫性诱剂悬挂在花生上方60 cm,使用小地老虎性诱剂悬挂在花生上方20～60cm,诱捕效果最佳;对两种靶标害虫,三角型诱捕器的日均诱蛾量均显著高于桶型诱捕器;从防治效果看,第一年小地老虎和棉铃虫幼虫虫口减退率分别为41.7%、40.0%,花生植株受害率分别降低44.4%、36.3%;连续诱捕两年后防治效果得到明显提高,幼虫虫口减退率分别为63.6%和69.6%,植株受害率分别降低60.0%和73.7%。The control experiments on black cutworm and cotton bollworm were conducted by using sex attractant in peanut field from 2011 to 2012, and the influences of suspension height and type of traps on trapping effect were tested. The results showed that the best trapping efficacy was achieved when the suspension height was at 60 cm above peanut plants for cotton bollworm, and from 20 cm to 60 cm above peanut plants for black cutworm. As for two target pest insects, the number of the moths trapped by triangular traps was significantly more than that by bucket traps. In the first year of this trapping study, the larvae densities of black cutworm and cotton bollworm were reduced by 41.7% and 40.0% respectively, and the damaged rates of peanut plants due to these two pest insects were decreased by 44.4% and 36.3% respectively. After continuous trials for two years, the control effect was markedly improved, the larvae densities of black cutworm and cotton bollworm were decreased by 63.6% and 69.6%, and the damaged peanut plants were reduced by 60.0% and 73.7% respectively.
