频振式杀虫灯在无公害蔬菜生产上的应用技术研究

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。

Application of frequency-vibrancy moth-killing lamp in the production of non-pollution vegetable

The frequency vibrancy moth killing lamp was effective for trapping many kinds of pests, especially for lepidopteral ones. The experiments showed that the amounts of eggs of Plutella xylostella, Spodoptera litura and Spodoptera exigua in the fields where the lamps were placed reduced by 51.9%, 69.5%and 79.2%, the amounts of larvae reduced by 64.6%, 69.3%and 88.8%respectively. The reduction of pesticide spraying was more than 70%as compared with those without lamps. And the following demonstration showed that it was unnecessary to control pests such as aphid, thrips and leaf miners (Liriomyza spp.) with pesticides in the fields using the lamps and yellow trap templates as well as other agricultural control strategies. The control input was only 3.2 yuan/mu annually and only 1.45%of chemical control costs. Application techniques of the frequency vibrancy moth killing lamps were summarized in this paper.
