为了探讨对二点委夜蛾成虫的高效防治措施,压低幼虫为害虫基数,笔者对二点委夜蛾成虫的夜间活动情况及不同杀虫灯管的田间诱捕效果进行了研究。结果显示,该虫成虫在傍晚天黑后飞翔活跃,至23时田间诱蛾量超过全天的70%。佳多频振式杀虫灯4#和19#灯管较常规的PS-15Ⅱ杀虫灯灯管对二点委夜蛾有更好的诱捕效果。
In order to investigate the effective control measures against adult worms of the second order, and to depress the larvae as the base of the pests, the authors studied the nighttime activity of the adult worms and the trapping effects of different insecticidal lamps. The results showed that the adult worm flew in the evening after dark, and the number of induced moths in the field was more than 70% of the whole day at 23 o’clock. Good multi-frequency vibration insecticidal lamp 4 # and 19 # lamp than the conventional PS-15II insecticidal lamp tubes on the second part of the night-stage moths have a better trapping effect.
