为了探索环保无公害的防控技术,笔者通过田间试验,评估了一种二点委夜蛾性诱剂诱芯的田间诱捕效果,并对其诱捕器不同口径、颜色、设置高度对诱捕效果的影响进行了研究。结果表明,该诱剂性诱芯对二点委夜蛾有较强的诱捕能力,最高日诱蛾量105头,最高日均诱蛾量40.25头;诱捕器的大小、颜色和高度都会影响诱捕效果。35 cm口径、绿色和设置在高出作物20～30 cm位置的诱捕器诱蛾量较大;性诱剂和杀虫灯对二点委夜蛾量的监测结果有一定差异。
In order to explore the environmental protection and pollution prevention and control technology, the author evaluated the field trapping effect of a sex attractant of two-part-time litura by field experiments and evaluated the trapping effect of different caliber, color and height of the trap The impact was studied. The results showed that the induced lure had stronger ability to secrete on the second instar larvae, with the highest number of lures and the highest number of lures of 40.25 per day. The size, color and height of the lures all affect the trapping effect. 35 cm caliber, green and trap were higher than the 20 ~ 30 cm position of the crop. The results showed that there were some differences between the sex traps and the insecticidal lamp on the quantity of the second instar Spodoptera litura.
