利用金龟子的选择取食特性诱杀金龟子,是“防治成虫与防治幼虫相结合”的综合防治策略中的一项新技术。七十年代末八十年代初,曾提倡人工捕捉金龟子,仅1979—1980年的两年间,赣榆县就人工收集金龟子达11万多斤。这无疑对压低田间蛴螬密度起了重要作用。1932年山东省农科院植保所提出用氧化乐果涂树干(或喷树叶)的方法,药杀前来群集取食的金龟子。这种方法虽较为有效,但由于农村实行大包干责任制后,分户防治有困
The use of chafer selection characteristics of trapping beetles, is “a combination of prevention and control of adult larvae and prevention and control,” a comprehensive prevention and control strategy in a new technology. In the late seventies and early eighties, artificially catching chafers were advocated. In the two years between 1979 and 1980, Ganyu County collected more than 110,000 kilos of beetles by hand. This undoubtedly plays an important role in reducing the density of the fields. In 1932, Shandong Academy of Agricultural Sciences proposed using the method of applying omethoate (or spraying the leaves) to kill chafers that came to cluster and feed. Although this method is more effective, but due to the implementation of the responsibility system in rural areas, household control difficult
