本文研究了FWS-DBL-1新型太阳能灭虫器在320～580、360、400、460和520 nm 5种不同波长下对吐鲁番葡萄产区害虫的诱捕效果及对天敌安全性。结果表明:在5种波长下,灭虫器诱捕昆虫的种类相似,以鞘翅目、鳞翅目、半翅目、脉翅目、双翅目、直翅目和膜翅目等为主。诱捕的主要昆虫是蜉金龟Aphodius sp.、白云斑鳃金龟Polyphylla alba vicaria Semenov、额喙丽金龟Adoretus nigriforns Steven、毛喙丽金龟Adoretus hirsutus Ohaus、绣罗夜蛾Leucanitis picta Christoph和淘赏夜蛾Catocala puerpera Giorna等。其中:灭虫器在400 nm波长下的诱捕量最多,其次是320～580 nm和360 nm波长。综合分析比较:400 nm波长对鞘翅目害虫的诱捕效果最好,360 nm波长对鳞翅目和双翅目害虫的诱捕能力最强,520 nm波长对半翅目害虫的诱捕效果最好。对天敌的安全性研究表明:FWS-DBL-1太阳能灭虫器对天敌有一定的诱捕作用,益害比为1∶4～1∶5。诱捕量较多的是步甲科和草蛉科的天敌,占天敌总诱捕量的85.82%。在这5个波长中,360 nm波长下,灭虫器对天敌的诱捕作用最小,对天敌的安全性相对较高。
In this paper, we studied the trapping effect of FWS-DBL-1 new-type solar insect-killing device on pests in Turpan grape region and its safety to natural enemies at different light wavelengths of 320 ~ 580,360,400,460 and 520 nm. The results showed that the species of insect traps were similar at 5 wavelengths, and were predominated by Coleoptera, Lepidoptera, Hemiptera, Diptera, Diptera, Orthoptera and Hymenoptera. The main traps were Trapacanthus Aphodius sp., Polyphylla alba vicaria Semenov, Adoretus nigriforns Steven, Adoretus hirsutus Ohaus, Leucanitis picta Christoph and Catocala puerpera Giorna and so on. Among them, the trapping device at 400 nm wavelength captured the most, followed by the 320 ~ 580 nm and 360 nm wavelength. The comprehensive analysis and comparison showed that the entrapment efficiency of the coleopteran pests was the best at 400 nm, and the entrapment efficiency of Lepidoptera and Dipterous pests at 360 nm was the strongest. The entrapment efficiency at 520 nm was the best. The research on the safety of natural enemies showed that the FWS-DBL-1 solar insect pest control device had a certain trapping effect on the natural enemies, and the harm-benefit ratio was 1: 4-1: 5. Trapping amount is more Carabidae and Gracilariaceae natural enemies, accounting for 85.82% of the total entrapment of natural enemies. At these 5 wavelengths, the insecticide has the least trapping effect on the natural enemies at the wavelength of 360 nm and the safety of the natural enemies is relatively high.
