摘要
对河南省新乡和驻马店地区的花生田地下害虫进行调查的结果表明，花生田的地下害虫主要包括蛴螬、金针虫、蝼蛄等，以蛴螬为主要地下害虫，7月下旬的平均虫口密度为0．80-18．90头／m2，9月下旬的平均虫口密度为1．00-12．33头／m2。经过分类鉴定暗黑鳃金龟（Holotrichia parallela Motschulsky）和华北大黑鳃金龟[Hoblita（Faldermann）]为花生田蛴螬优势种。调查还发现，土壤类型、耕作方式、田间周围的植物布局及防治措施均对蛴螬的种群数量有明显影响。
The peanut fields in Xinxiang and Zhumadian in Henan were investigated. The results showed that the soil-inhabiting pests include Scarabaeidae, Elateridae and Gryllotalpidae. As the main pests, the density of Scarabaeidae was 0. 80--18. 90 per square meter in July, 1.00--12.33 per square meter in September. Holotrichia parallela and H. oblita were dominant pest species. Soil types, culture modes, environment and measures of pest control could influence the density of soil-inhabiting pests.
