摘　　要：为探明滨海稻区灯诱昆虫群落组成及其对主要害虫灯诱效果,采用波长365 nm的自动虫情测报灯统计分析灯诱昆虫种类及益害比情况,并对比田间二化螟和稻飞虱发生动态。结果表明:滨海稻区灯诱昆虫共有8目、28科、42种,共计62031头昆虫个体,主要为鞘翅目、鳞翅目和双翅目,对主要害虫二化螟灯诱效果同田间查卵的动态趋势基本一致,对主要害虫稻飞虱灯诱效果与田间查虫趋势略有差异。因此,灯诱监测较适合监测二化螟,而不适合监测稻飞虱,灯诱昆虫益害比为1∶13.94。To explore the light trapping insect community composition and its trapping effects on main pests in coastal rice region,automatic worm situation forecast lamp with wavelength 365 nm is used to conduct statistical analysis of the light trapping insect species and calculate ratio of their benefit to harm,and compare the occurrence dynamics of Chilo suppressalis with rice planthopper in the field.The results showed that there were 8 orders,28 families and 42 species of light trapping insects in the coastal rice region,a total of 62031 individual insects,including Coleoptera,Lepidoptera and Diptera.In addition,the light-trapping effect on the main pest Chilo suppressalis was basically consistent with the dynamic trend of egg detection in the field,and its effect on the main rice planthopper was slightly different from the trend of checking insects in the field.Therefore,the light-trap monitoring is more suitable for the Chilo suppressalis rather than rice planthopper,the benefit-harm ratio of insects induced by light is 1∶13.94.
