大黑金龟子是我国北方旱作地区农田蛴螬的优势虫种,其四个虫态中,以成虫和初孵幼虫的抗药力最差,是防治上的主攻环节。但因幼虫生活在地下,在防治季节内多干旱少雨,农药很难渗透全土层,防效不理想。在成虫防治上,各地采取了撒毒土、地面喷粉和地面喷雾的防治方法,收到了较好的效果,但存在一定的问题:一是田内大量施药,污染土壤,杀伤天敌,使农产品残毒量升高;二是技术复杂,成本大,经济效益低。笔者根据大黑金龟子出土早,活动能力差,出土高峰整齐,出土后必须取食植物叶片补充营养的特性,于1985~1987年进行了毒枝、毒叶诱杀大黑金龟子配套技术的研究与应用。
Large black beetle is the dominant species of farmland in the dry farming areas of northern China. In the four insect states, the resistance to adult and newly hatched larvae is the worst, which is the main link in prevention and control. However, because the larvae live in the ground and are more arid and rainier in the control season, it is very difficult for pesticides to penetrate the soil layer and the control effect is not satisfactory. In the prevention and treatment of adult insects, various localities have adopted the methods of prevention and control of soil spraying, ground dusting and ground spraying, and have received good results. However, there are some problems. First, a large number of pesticides are applied in the fields to pollute the soil and kill natural enemies, Second, the technical complexity, cost, low economic efficiency. The author based on the black beetle unearthed early activity ability is poor, unearthed peak tidy unearthed must eat plant leaves to supplement nutrition characteristics, from 1985 to 1987 for the poison sticks, poisonous leaf trapping big black beetle supporting technology research and application .
