摘要: 为探讨昆虫性信息素智能迷婚剂对二化螟的防控效果, 设置智能迷婚剂, 利用性诱剂进行了田间蛾量调查, 并调查了二化螟的危害情况, 发现迷向防治区性诱剂引诱的二化螟总量明显低于药剂防治区, 同时, 迷向防治改变了性诱剂的诱蛾动态. 当田间蛾量较大时, 药剂防治区的诱蛾量明显高于迷向防治区, 且差异具有统计学意义. 迷向法防治后, 水稻二化螟的危害株率明显降低, 防效为92.3%±1.8%, 防效明显高于药剂防治区. 研究结果表明, 昆虫性信息素智能迷婚剂是水稻二化螟的一种高效绿色防控技术, 能大量减少化学农药的使用.Abstract: In order to explore the effect of intelligent sex pheromone mating disruption sprayer on controlling rice stem borer Chilo suppressalis, intelligent sex pheromone sprayers were set up for disruption the mating. The number of moths was monitored using sex pheromone attractants and the harm of C. suppressalis to rice was investigated in the study. The total number of moths attracted by sex pheromone attractants in the sprayer controlling area was significantly lower than that in the pesticide controlling area. At the same time, sex pheromone sprayers changed the dynamics of trapping the moths. The number of moths attracted by sex pheromone in pesticide control area was significantly higher than that in the sprayer controlling area, when the number of moths in the field is large. Compared with pesticide, sex pheromone sprayer significantly reduced the damage rate of C. suppressalis and significantly increased the control effect to 92.3%±1.8%. Our results indicate that intelligent sex pheromone mating disruption sprayer is an efficient and green control technology for Rice Stem Borer, and can significantly reduce the use of chemical pesticides.
