2009-2011年连续3年利用频振式杀虫灯调查安徽省花生田3种常见金龟子成虫的种群动态,结果表明:2009-2011年3种金龟子灯诱总数整体呈下降趋势,且诱捕量为铜绿丽金龟>暗黑鳃金龟>华北大黑鳃金龟。华北大黑鳃金龟趋光性差,灯诱量低;暗黑鳃金龟和铜绿丽金龟初见日一般为5月中下旬,高峰期为6月中旬,但暗黑鳃金龟比铜绿丽金龟一般晚7-10 d。金龟子出土与气候关系密切,当平均气温上升至20℃-25℃持续数日并保持上升的过程中,暗黑鳃金龟和铜绿丽金龟诱捕量增大,但性比未呈现规律性差异。
The population dynamics of three common beetle adults in Peanut Field in Anhui Province during 2009-2011 were investigated using frequency-vibration pest-killing lamps. The results showed that the total number of three kinds of chafer beetles showed a decreasing trend from 2009 to 2011, and the trapping amount was Copper green beetle> Dark gill beetle> North China gill beetle. North China black glitch poor phototropism, light-induced low; Diabrink beetles and copper green beetle first see Japan generally in late May, the peak of mid-June, but the dark gill beetle than the copper green beetle generally late 7-10 d. When the average temperature rose to 20 ° C-25 ° C for several days and kept rising, the burrowing amount of the scarabs and the copper beetle increased, but the sex ratio did not show the regularity.
