【摘要】 通过种植麦套春棉、麦套春棉播种玉米诱集带、麦套春棉邻近种植玉米三种类型的棉田，以平作春棉为对照。明确了不同类型生态区的主要害虫及天敌种群消长动态。立体种植棉田与平作春棉相比：盛期平均百株黄地老虎为害降低８７．５％；棉叶螨发生早为害重；苗蚜降低９７．８％，差异极显著；伏蚜发生量上升２０２％，差异显著；第二代棉铃虫落卵士降低３３．８％；三、四代棉铃虫落卵量差异不显著。第二代棉铃虫发生期，玉米诱集带百株累计诱集棉铃虫落卵量达１４８４粒，天敌数量最高达８４０头，明显看出种植玉米诱集带对棉铃虫有较好的诱集作用，对天敌有很好的保护和增殖作用。更多还原

【Abstract】 Three different plantingpattern of cotton/wheat,cotton/wheat with thetrapped corn and cotton/wheat with the skipped corn, were studied by comparising withthe single spring cotton. The population dynamic of principal cotton pests and their ene-mies were demenstrated.Comparising the wheat一cotton interplanting with the singlespring cotton,the Euxoa segetum decreased 87.5%; the red spider mite occurred earlierand more serious damage;the aphids during the seedling stage reduced 97.8%; while theaphids in mid season increased 202%; the number of eggs of CBW decreased 33.8% in thesecond generation; not different in the third, fourth generation. There were l484 eggs,840 ratural enemies in l00 corn plants of the trap crop, which showed very good trap ef-fect, as well as it can protect and increase the population of the natural enemies.更多还原
