【摘要】 对新型飞蛾干式诱捕器诱捕效率进行了测试,从6月20日至9月20日,共调查13次,累计诱蛾量8 605头,平均每台诱捕器诱蛾344头。性诱剂处理区、施药区和不施药区虫伤株率分别为为1.77%、1.19%和81.90%,枯鞘率分别为1.11%、0.65%和14.68%,白穗率分别为1.87%、0.35%和38.83%。性诱剂防治效果95.18%,比药剂防效低3.92个百分点。就本试验结果来看,新型诱捕器操作简便,易于维护,使性信息素大面积诱杀二化螟的可行性提高。更多还原

【Abstract】 The trap efficiency of new dry moth traps to Chilo suppressalis was tested in this paper, total investigation of 13 times from June 20 to September 20, the cumulative moth amount is 8 605, the average per trap moth was 344. The attracting rate of sex attrac-tant area,normal pesticide application area and no pesticide area was 1.77%, 1.19% and 81.90%, respectively. The rate of withered sheath was 1.11%, 0.65% and 14.68%, respectively. The rate of white head was 1.87%, 0.35% and 38.83%, respectively. The control effect of sex pheromone was 95.18%, 3.92 percentage point lower than that of the pesticide application area. The results showed that the new dry moth trap has the advantages of simple operation, low maintenance cost, time saving and labor saving.更多还原
