性诱剂监测丘陵地区稻纵卷叶螟的效果

Effect of Applying Sex Pheromone in Monitoring Cnaphalocrocis medinalis in Hilly Regions

为探究性诱剂在丘陵地区稻纵卷叶螟预测预报上的应用效果,以稻纵卷叶螟性信息素为材料,于2014年5~10月在湖南省汨罗市开展了稻纵卷叶螟田间消长动态的监测研究。结果表明,与自动虫情测报灯和田间系统赶蛾等常规方法相比,稻纵卷叶螟性诱剂的诱蛾量相对偏少,自动虫情测报灯、田间系统赶蛾与性诱剂诱集的诱杀比分别为13.5︰1、23.5︰1;但其对稻纵卷叶螟的数量动态变化的监测与常规方法基本一致,蛾高峰出现日期准确。综合来看,性诱剂可用于湖南丘陵地区迁飞性害虫稻纵卷叶螟的田间监测,为该地区统防统治技术的推广,特别是大面积植保无人机防治提供更加准确快速的预测信息,同时可显著降低人工测报的劳动强度。

In order to explore the application effect of sex pheromone in forcasting Cnaphalocrocis medinalis in hill regions, the study taking its sex pheromone as the material, monitored the population dynamic of Cnaphalocrocis medinalis in Miluo city, Hunan province from May to August 2014. The results showed that compared with conventional methods like automatic pest forecast light method and systematic investigation, the quantity of moth catches by sex pheromone trap method was less, and the ratios of attracted to killed moths by conventional methods and sex pheromone trap method were 13.5 ： 1 and 23.5 ： 1 respectively; however, the population dynamics monitored by all methods were similar which indicated moth appearance peak date accurately. On the whole, sex pheromone could be used to monitor the population dynamic in Hunan hilly regions, which could provide more accurate and fast prediction information for the popularization of pest control techniques, especially using unmanned aerial vehicle in plant protection of large areas, and reduce labor intensity of pest forecasting.
