性诱剂诱捕器对玉米螟的田间防治效果

摘要

为确定性诱剂诱捕器对玉米螟的田间防治效果及设置的最佳数量，试验在田间设置不同数量的玉米螟性诱剂诱捕器，对诱捕玉米螟成虫数量、平均防治效果、挽回产量损失率进行调查。结果表明：每667 m2设置1个性诱剂粘胶诱捕器较适宜，平均每天每个诱捕器诱捕到玉米螟雄成虫数量为1．70头，平均防治效果为45．27％，挽回产量损失率为5．56％。%In order to determine field control effects and quantity of sex pheromone traps on maize borer .The basic adult numbers ,control effects and yield loss rate were investigated through setting different amount of maize borer sex pheromone traps in field .The results showed that the more suitable number of sex pheromone trap was one in 667 m2 ,the trapped basic male adult numbers of maize bore was 1 .70 every day ,the average control effect was 45 .27% ,and the redemptive yield loss rate was 5 .56% .
