摘　　要：对非洲蝼蛄 (GryllotalpaafricanaPalisotdeBeauvios)、暗黑金龟 (HolotrichiaparllelaMotschulsky)和铜绿金龟 (ApomalacorpulentaMotschulsky)成虫在 3种不同诱虫灯下的夜间上灯节律进行了研究。表明在 3种不同灯下 ,上述 3种害虫的上灯节律基本趋于一致 ,全夜各有 1个上灯高峰 ,均在开灯后 1h内 ,上灯比例分别为全夜的 37 39%、 40 49%和 48 2 0 %。进行综合各灯种逐时段的上灯累积百分率分析 ,发现该 3种害虫到凌晨 1∶0 0止 ,累积上灯百分率分别为全夜诱虫量的 88 69%、 88 30 %和 85 63% ,据此 ,可以结合田间实际虫情和防治要求 ,将凌晨 1∶0 0确定为最佳关灯时间 ,以节约诱虫成本。The authors had a two year research on the rule of three pests′, Gryllotalpa africana Palisot de Beauvios, Holotrichia parallela Motschulsky and Anomala corpulenta Motschulsky , response to different light traps in the night in 1999 and 2000. The results show that these pests have the same trend of the trapped percentage by three light traps at each time in the night. They only have one peak after the different light is opened an hour later in the all night, when they throw themselves on a light. The percentage of high response peak of three pests is 37 39%, 40 49% and 48 20% respectively. An analysis of accumulative trapped percentage of these pests at each time in the all night is conducted . It is found that accumulative trapped percentage till 1∶00 in the next morning of these pests is 88 69%,88 30% and 85 63% respectively. So 1∶00 a m. can be used as the best time of cutting off the light trap, to save the cost of these pests control.
