| 中文摘要: |
| 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7-10d。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。 |
| 英文摘要: |
| By using light trapping technique, we investigated the population dynamics of three kinds of common peanut scarabs in Anhui Province from 2009 to 2011. The results showed that: The catch of three scarabs declined gradually from 2009 to 2011, the number indicated that Anomala corpulenta > Holotrichia parallela > Holotrichia oblita. With inferior phototaxis, the catch of H. oblitawas the fewestA. corpulenta and H. parallela appeared for the first time in mid to late May, and the trapping peak of them were in mid June. In general, A. corpulenta appeared 7-10 days after H. parallela. The appearance of scarabs had deep relationships with climate. The catch of A. corpulenta and H. parallela increased when the average temperature was rising to 20℃ - 25℃ for several days and kept rising. However, there was no regular difference in sex ratio. |
