贵州玉米田害虫绿色灯光防控技术研究

为探明贵州玉米田昆虫群落结构和杀虫灯对害虫的防治效果，选取贵州玉米田3个具有代表性的点分别安装诱虫灯，进行诱集调查，并对近灯区（距离灯20 m以内）、远灯区（距离灯20~150 m）和对照区的昆虫种群消长情况进行田间调查。结果表明，贵州玉米田昆虫共有11目66科132种，主要为同翅目、鞘翅目、鳞翅目、膜翅目、直翅目、双翅目和半翅目类昆虫；灯诱共获得89个种类，其中害虫占64.77%，益虫占15.91%，中性昆虫占19.32%。田间调查结果显示，近灯区物种丰富度最高，对照区次之，远灯区最低；近灯区玉米螟Ostrinia furnacalis、黏虫Mythimna seperata (Walker)、灰飞虱Laodelphax striatellus和条赤须盲蝽Trigonotylus coelestialium (Kirkaldy)等趋光性昆虫的种群数量长期高于其他区域。综上所述，风吸式诱虫灯对玉米田害虫有较好的防治效果，为玉米田害虫的绿色防控提供了参考。

Research on green light control technology of insect pests in corn fields in Guizhou

The structure of the insect''s community and trapping effect of insecticidal lamps on cornfield pests were investigated in Guizhou. Three representative spots to install trap lights were selecting for trapping investigation in cornfields in Guizhou. The insect populaiton in the near-light (within 20 m from the lights), far-light (20-150 m) and control areas were investigated, respectively. Results indicated that there were 11 orders, 66 families and 132 species of insects in cornfields in Guizhou, mainly including Homoptera, Coleoptera, Lepidoptera, Hymenoptera, Orthoptera, Diptera and Hemiptera. A total of 89 insect species were obtained by using the trap lights method, of which 64.77% were pests, 15.91% were beneficial insects, and 19.32% were neutral insects. Furthermore, the population numbers of photophic insects, such as Ostrinia furnacalis, Mythimna seperata, Laodelphax striatellus, and Trigonotylus coelestialium, were higher than those of other regions in the near lamp area. In conclusion, the trap lights had a good trapping effect on cornfield pests, providing a reference for green control technology of cornfield pests.
