杀虫灯对谷子和高粱上鳞翅目害虫的诱杀效果初报

Preliminary Report on the Trap Effect of Insecticidal Lamps on Lepidopteran Pests on Millet and Sorghum

[目的]评价杀虫灯对谷子田和高粱田中鳞翅目成虫的诱杀效果。[方法]2020年,在邯郸武安谷子田和衡水景县高粱田开展田间试验。[结果]供试杀虫灯可有效诱捕棉铃虫、玉米螟、黏虫及桃蛀螟等鳞翅目害虫的成虫,单日平均诱虫量为6.91~12.15头/灯,峰日诱虫量高达103头/灯。[结论]灯上成虫数量变化趋势与田间消长动态基本一致,可用于谷子和高粱田中鳞翅目成虫的监测与防治。

[Objective]To evaluate the trapping effects of Lepidoptera adults in the fields of millet and sorghum.[Method]In 2020,the trapping effect of insecticidal lamp on Lepidoptera adults was evaluated in the millet field of Wu’an in Handan and sorghum field of Jingxian in Hengshui.[Result]The insecticidal lamps could effectively trap the adults of Lepidoptera pests such as Helicoverpa armigera,Pyrausta nubilalis,Mythimna separata and Conogethes punctiferalis.The average daily trapping amount was 6.91-12.15 heads/lamp,and the peak daily trapping amount was as high as 103 heads/lamp.[Conclusion]The variation trend of adults number on the lamp was basically consistent with the growth and decline of the field,which could be used for the monitoring and control of lepidoptera adults in millet and sorghum fields.
