中文摘要:
      为明确杀虫灯对亚洲玉米螟Ostrinia furnacalis和草地贪夜蛾Spodoptera frugiperda的杀虫效果, 分别对2种害虫人工饲养的成虫进行颜色标记后, 在距频振式太阳能杀虫灯不同距离处释放, 根据杀虫灯下回收数量确定有效防控距离。同时对高空测报灯和自动虫情测报灯2种不同光源测报灯诱集到的2种害虫的性比进行分析。结果表明, 在距杀虫灯15~45 m内, 亚洲玉米螟的回收率随着距离的增加呈上升趋势, 距灯45 m的回收率最高, 为4.95%, 在距离增加到60 m时, 回收率显著下降。草地贪夜蛾在距灯30 m处的回收率为6.08%, 随着离灯距离的增加, 雌、雄蛾回收率均呈下降趋势, 且回收的雌蛾比例减少。杀虫灯在1.2 m高度时对亚洲玉米螟的回收率高于1.5 m和1.8 m, 3个高度雄蛾的回收率均高于雌蛾, 随着高度增加, 回收率下降, 雌蛾的回收比例也呈下降趋势。高空测报灯和自动虫情测报灯捕获的2种害虫雌雄性比均低于0.45∶1, 2种害虫的趋光性均存在雄性偏好。
英文摘要:
      In order to clarify the insecticidal effect of insecticidal lamps on Asian corn borer, Ostrinia furnacalis, and fall armyworm, Spodoptera frugiperda, the adults of the two pests artificial reared were color-marked, released at different distances from the insecticidal lamps, and recaptured by insecticidal lamps. Effective control distance was determined according to the number of recaptured adults under insecticidal lamps. At the same time, sex ratio of two pests trapped by different light sources were analyzed after long-term monitoring. The results showed that recapture rate of O. furnacalis increased with the distance from 15 to 45 m. The highest recapture rate was 4.95% at 45 m from the lamp, and significantly decreased when the distance increased to 60 m. Recapture rate of S.frugiperda at 30 m from the lamp was 6.08%, and the recapture rate of both female and male moths showed a decreasing trend with the increase of distance from the lamp, and the proportion of recaptured female moths decreased. Recapture rate of O. furnacalis at 1.2 m height was higher than that of 1.5 m and 1.8 m. Recapture rate of male moths was higher than that of female moths at all three heights, and the recapture rate decreased with increasing height, and the proportion of female moths recaptured also showed a decreasing trend. Female to male ratios of both pests trapped by both searching light and automatic pest forecast light were lower than 0.45∶1, and there was a male preference for phototropism of both pests.
