应用性诱剂、杀虫灯等绿色防控方法对烤烟生产中害虫成虫进行诱杀,对其幼虫的发生与危害进行有效控制。其中利用性诱剂诱杀效果最好为斜纹夜蛾诱芯,平均每个诱捕器诱杀成虫163.4头;使用频振式杀虫灯对鞘翅目(金龟子)和其它蛾类的昆虫有非常明显的诱杀功效,平均每盏杀虫灯诱杀达4 493.6头。使用性诱剂每667 m2用杀虫剂成本减少5.87元;杀虫剂每667 m2用量减少0.051 kg;杀虫剂每667 m2用工数减少0.4个工;用药次数减少1.4次;杀虫剂每667 m2用工成本减少24元。使用杀虫灯每667 m2用杀虫剂成本减少2.72元、杀虫剂每667 m2用量减少0.04 kg、杀虫剂每667 m2用工数减少0.4个、用药次数减少1.4次、杀虫剂每667 m2用工成本减少24元。从而达到减少农药使用量、降低烟叶农药残留,提高烟叶产品安全性,减少对环境的污染,实现烟叶生产的可持续发展。
Application of lures, insecticidal lamps and other green control methods for the production of flue-cured tobacco pests adult trapping, the larvae of the occurrence and harm of effective control. Among them, the trapping and killing effect of sex attractant was the lure of Spodoptera litura, with an average of 163.4 adult traps per trap. The use of frequency-vibration insecticidal lamp had very obvious trapping and killing effects on Coleoptera (Scarabaeidae) and other moth insects Efficacy, an average of 4 493.6 trapping kill lights per killing lamp. The cost of insecticide used per 667 m2 was reduced by 5.87 yuan with the use of sex attractants, 0.051 kg per 667 m2 of pesticides, 0.4 labor per 667 m2 of pesticides, 1.4 times less by drug use, 667 m2 labor costs reduced by 24 yuan. The cost of using insecticidal lamps per 667 m2 was reduced by 2.72 yuan, the dosage of pesticides was reduced by 0.04 kg per 667 m2, the number of pesticides per 667 m2 was reduced by 0.4 and the number of medication was reduced by 1.4 times. The pesticides per 667 m2 labor costs to reduce 24 yuan. So as to reduce the use of pesticides, reduce tobacco leaf pesticide residues, improve the safety of tobacco products, reduce environmental pollution and achieve sustainable development of tobacco production.
