频振式杀虫灯杀虫谱广,尤其对鳞翅目害虫的控害效果显著。试验结果表明,挂灯区小菜蛾、斜纹夜蛾、甜菜夜蛾的落卵量比无灯区分别下降51.9%、69.5%和79.2%,幼虫量比无灯区分别下降64.6%、69.3%和88.8%,生产中减少害虫防治用药70%以上。示范应用结果表明,灯控区配以黄板诱杀蚜虫、蓟马、斑潜蝇和其他农业防治措施后,基本不需施药治虫,年防治投入仅需3.2元/亩,其成本仅为化学防治成本的1.45%。在试验、示范的基础上,总结提出了频振式杀虫灯的应用技术。
Vibrating insecticidal lamp insecticidal spectrum wide, especially Lepidoptera pest control effect is remarkable. The results showed that the number of larvae of Plutella xylostella, Spodoptera exigua and Beet armyworm dropped 51.9%, 69.5% and 79.2% respectively in the hanging lamp area, and the larvae decreased by 64.6%, 69.3% and 88.8%, reducing pest control over 70% in production. Demonstration application results show that the light control area together with the yellow board trapping aphids, thrips, leafminers and other agricultural control measures, the basic need of insecticide, the annual investment in prevention and control only 3.2 yuan / mu, the cost of only chemical Prevention of 1.45% of the cost. On the basis of experiments and demonstrations, the application technology of frequency-vibration pest-killing lamps is summarized.
