2011年应用黏胶型性诱剂诱捕器和虫情测报灯两种诱测方法在达县进行了对水稻二化螟监测效果的对比试验。结果表明,黏胶型性诱捕器监测二化螟效果好,具有诱蛾量大、性能稳定、峰型明显、预警准确性高等特点,在各代成虫诱测中,效果优于虫情测报灯;性诱剂诱捕器监测对二化螟还具有一定兼治作用,1代枯鞘株率防效达33.24%、2代白穗率防效达27.51%。同时,分析了作物生育期、气象因子和非靶标昆虫对性诱捕效果的影响。讨论了性诱捕器在二化螟监测预警与控制技术的推广应用中应注意和需进一步研究的问题。
In 2011, the viscose lure trap and the insect detection lamp were used to test the effect of the rice stem borer, Chilo suppressalis, in Daxian. The results showed that the viscose trap was effective in monitoring the rice stem borer (STI). It had the characteristics of large amount of moth, stable performance, obvious peak shape and high warning accuracy. The monitoring of lure trap also had some effects of controlling S. chilonicus. The control efficiency of the 1st generation sheath blight was 33.24%, and the control efficiency of 2nd generation white spike reached 27.51%. At the same time, the effects of crop growth period, meteorological factors and non-target insects on sexual trapping were analyzed. The problems of sexual traps should be noticed and need to be further studied in the popularization and application of the technology of monitoring, warning and control of stem borer.
