摘要
为明确二化螟性诱剂与不同色板、灯光组合对水稻、茭白田二化螟成虫的诱集效果,筛选和确定适合二化螟诱捕监测的优选材料,为该害虫的虫情监测及其应用开发提供参考依据。将二化螟性诱剂分别与2种色板(黄色、绿色)和2种诱虫灯(黑光灯、紫外灯)组合进行比较试验,结果表明,性诱剂与绿板组合对二化螟的诱捕效果显著优于其他组合(P<0.01);黄板组合对天敌昆虫的诱捕效果显著,绿板则对非靶标害虫的诱捕效果显著;诱虫灯(尤其是黑光灯)组合对非靶标螟虫类的诱捕效果显著。虫情动态分析可知,余姚水稻田二化螟成虫的高峰期为5月中旬,茭白田二化螟成虫的发生高峰期为7月中旬。因此,在水稻、茭白田二化螟防控时应合理、适时、适地选择应用色板、诱虫灯及性诱剂组合,避开天敌昆虫的盛发期,达到二化螟成虫种群发生动态的精确监测和精准防控的目的。
In order to clear the attractant effect of sex pheromone,sticky color plate and light trap on striped stem borer Chilo suppressalis in rice and water-oat fields,the optimal materials suitable for trapping and monitoring the C.suppressalis were screened,and provide information for insect monitoring and application development of the pest.In this study,two kinds of sticky color plates(yellow and green)and two kinds of light traps(black light and ultraviolet light)were compared.The results showed that the combination of sex pheromone and green plate was significantly better than other combinations(P<0.01).The yellow plate combination had a remarkable trapping effect on natural enemy insects,while the green plate combination had a remarkable trapping effect on non-target pests.The combination of light trap(especially black light)had a remarkable trapping effect on non-target borers.According to the dynamic analysis of insect situation,the occurence peak of the adult C.suppressalis was mid-May in rice field,and mid-July in water-oat field in Yuyao.Therefore,it was necessary to combination sticky color plate,light trap and sex pheromone reasonably,timely and appropriately to avoid the blooming period of natural enemies,so as to achieve accurate monitoring and control of adult population dynamics of the C.suppressalis.
