摘　　要：通过对诱捕器不同悬挂高度和颜色对玉米螟成虫诱捕效果研究,明确了诱捕器悬挂高度以1.5~2.0 m诱捕效果较好,颜色对诱捕器的诱捕效果影响不大。同时,对安放不同密度玉米螟性信息素诱芯诱捕玉米螟成虫进行了研究。结果表明：玉米螟性信息素诱芯可以诱捕玉米螟成虫,进行短期预报具有可行性。同时,采用玉米螟性信息素诱芯可诱捕玉米螟成虫、使卵和幼虫减少,减轻危害。以每公顷10个诱芯较好,卵和幼虫数量明显减少,比空白对照增产8.61%。A comparative study was conducted on the different hanging height ot traps and different color traps on capture of Asian Corn Borer. The result indicted that the more suitable hanging height of the traps were 1.5m - 2.0m, and the trapping effects with five colors did not differ significantly. The sex pheromone traps were placed in corn field with different density. The results showed that sex pheromone could trap Asian Corn Borer, and it was feasible applying sex pheromone in forecast. Meanwhile, it could reduce the number of larva and egg of Asian Corn Borer. The density of 10 traps in 1 hectare was better than others, of which the yield was 8.61% more than the control.
