太阳能光陷阱捕虫器对花生田昆虫的诱捕效果

为建立绿色高效的花生田害虫灯光诱控技术，于2019年在湖北省孝感市大悟县河口镇群建村进行试验，测定光源A（波长365 nm）和光源B（波长390 nm）太阳能光陷阱捕虫器诱捕到的花生田地下害虫、天敌昆虫和中性昆虫的类群和数量，并分析不同光源和天气对太阳能光陷阱捕虫器诱捕效果的影响。结果表明，2种光源太阳能光陷阱捕虫器共诱捕昆虫106 899头，其中地下害虫以丽金龟科和鳃金龟科昆虫居多，分别为53 338头和22 993头；诱捕的天敌昆虫和中性昆虫中分别以步甲科昆虫和水龟虫科昆虫居多，分别为1 495头和4 866头。光源A诱捕的金龟甲总科害虫、叩甲科害虫、天敌昆虫和中性昆虫数量与光源B的诱捕量均差异不显著，但光源A诱捕的蝼蛄科害虫数量显著高于光源B；晴天诱捕的金龟甲总科害虫、叩甲科害虫、天敌昆虫和中性昆虫数量与在阴天的诱捕量差异不显著，但晴天诱捕的蝼蛄科害虫数量显著高于阴天的诱捕量。表明太阳能光陷阱捕虫器对花生田害虫的诱捕效果好，对天敌昆虫和中性昆虫杀伤力小，可作为一种绿色防控手段防治花生田害虫。

Trapping effects of solar light traps on insects in peanut fields

In order to establish a green and efficient light trapping and control technology for insect pests in peanut fields, a field test in Qunjian Village, Hekou Town, Dawu County, Xiaogan City, Hubei Province was conducted in 2019 to determine the groups and numbers of underground pests, natural enemy insects and neutral insects trapped by solar light traps(Light source A with 365 nm wave length and Light source B with 390 nm wave length) in peanut fields. The effects of different light sources and the weather on the trapping efficiency of solar light traps were analyzed. The results showed that 106899insects were trapped by the two light sources. The majority of the underground insect pests belonged to Rutelidae(53338) and Melolonthidae(22993), and the majority of trapped natural enemy insects and neutral insects belonged to Carabidae(1495) and Hydrophilidae(4866), respectively. The numbers of Scarabaeoidae pests, Elateridae pests, natural enemy insects and neutral insects trapped by Light source A were not significantly different from those trapped by Light source B. However, the number of Gryllotalpidae pests trapped by Light source A was significantly higher than that trapped by Light source B. In addition, there were no significant differences in the trapping numbers of Scarabaeoidae pests, Elateridae pests, natural enemy insects and neutral insects between sunny and cloudy days, although the trapping number of Gryllotalpidae in sunny days was significantly higher than that in cloudy days. In conclusion, solar insect light traps had perfect trapping effect against peanut insect pests with only minimal negative effect on natural enemy insects and neutral insects, and thus can be use as a green control method against peanut insect pests.
