黄冈市花生田暗黑鳃金龟子出土规律研究

Studies on Rules of the Coming up out of the Ground of Holotrichia parallela Motschulsky in Peanut Field of Huanggang

通过性引诱剂诱捕暗黑鳃金龟子(Holotrichia parallela Motschulsky),研究了暗黑鳃金龟子在黄冈市的发生规律:隔日出土,出土时段遇大风雨顺延至次日出土;19:30以后开始出土,背覆式交尾,20:05交尾基本结束;具有明显的趋光性和假死性。

Trapping Holotrichia parallela Motschulsky with sex attractant,the occurrence regularity of Motschulsky was studied. Results showed that Holotrichia parallela Motschulsky came up out of the ground after 19：30 every other day, and the pro- cess would be delayed to the next day when awful storm came. The face-to-back copulation was adopted and mainly ended at 20：05. Moreover, Holotrichia parallela Motschulsky had obvious phototaxis and death-feigning behavior.
