摘　　要：2011～2012年在湖北省大悟县新城镇花生田比较了5种频振灯光源对花生田天敌昆虫的诱集作用。五种光源在花生田诱集到的主要天敌有瓢虫、寄生蜂、草蛉、隐翅甲和步甲。灯诱结果表明:2011年5月8日和2012年7月18日是瓢虫的两个高峰日;2011年5月8日和2012年4月18日是寄生蜂的两个高峰日;2011年5月8日是草蛉的高峰日;2011年5月31日和2012年5月12日是隐翅甲的高峰日;2011年5月8日是步甲的高峰日。在五种光源中,光源Ⅳ对瓢虫杀伤力最小,光源Ⅱ对寄生蜂和草蛉杀伤力最小,光源Ⅴ对隐翅甲和步甲杀伤力最小。综合分析表明,光源Ⅳ对花生田天敌昆虫的总杀伤力最小。研究结果不仅筛选出对花生田天敌昆虫杀伤力最小的光源,而且明确了天敌昆虫容易遭受杀伤的时间。Light trapping technique is an important measure of pollution - free pest control, but it has killing effect on natural enemies to some degree. From 2011 to 2012, the attracting effects on natural enemies among five light resources of frequoscillation pest - killing lamp were investigated in the peanut field of Xincheng Town, Dawu County, Hubei Province, China. The results showed that five main natural enemies included ladybirds, parasitic wasps, lacewings, rove beetles and carabid beetles were trapped in the peanut field. The attracting peak date of them was the same in the year of 2011 and it was May 8 except rove beetles whose was May 31. However, they didn＇t appear to exhibit uniformity in 2012 and the attracting peak dates of ladybirds, parasitic wasps and rove beetles were July 18, April 18 and May 12 respectively. Moreover, the results indicated that Light resource IV, [[ and V had the least killing effect on ladybirds, parasitic wasps and lacewings, rove beetles and carabid beetles respectively. Comprehensive analysis showed that Light resource 1V among the five light resources had the least killing effect on natural enemies in peanut field. These findings not only screened the best light resource of protecting main natural enemies, but also cleared the time when natural enemies were easily killed in peanut field.
