大眼隐翅虫的交配行为

Mating Behavior of the Stenus(s. str.)sp. (Coleoptera:Staphylinidae)

采用室内饲养观察的实验方法对大眼隐翅虫Stenus(s.str.)sp.的交配行为进行观察研究.结果发现:大眼隐翅虫Stenus(s.str.)sp.完成一次交配行为经过相遇、抱对、锁结、离开等几个过程.本文描述了大眼隐翅虫Ste-nus(s.str.)sp.交配行为的过程,记录抱对和锁结发生的时间.在2008年10月到2009年1月的饲养过程中大眼隐翅虫Stenus(s.str.)sp.在11月2日到11月8日一周时间内发生交配行为,第三天交配对数最多,且交配大多发生在上午9:00-11:00;记录抱对和锁结所经历的时间统计描述出,抱对2m in左右,锁结时间长达0.5h.

Mating behavior of the Stenus（s. str. ） sp. was observed by the laboratory. The results showed that a complete mating of the Stenus（s. str. ）sp. involved four stages： encountering,hugging,interlocking and leaving . This paper described the procession of mating behavior of the Stenus （ s. str. ） sp and recorded the time when the hugging and interlocking occurred. During the process of rearing the Stenus （s. str. ） Sp from October 2008 to January 2009, we found the mating behavior occurred between the November 2nd and Nor.ember 8th nearly, a week, and the mating mostly occurred between 9 ： 00am-11 ： 00am and the number of the mating reaced the peak value in the third day. The time of hugging lasted about two minutes and that of interlocking lasted about half an hour.
