摘　　要：【目的】竹林金针虫是我国南方地区1种重要的竹林地下害虫,研究其成虫求偶及交配行为对于该虫性信息素引诱剂的研发及应用有着重要意义。【方法】利用昆虫夜间行为观测的方法对筛胸梳爪叩甲(Melanotus cribricollis)雌、雄成虫的求偶、交配行为特征及节律进行了研究。【结果】筛胸梳爪叩甲成虫的求偶及交配行为表现出明显的阶段性特征,进入暗期90 min后开始发生求偶和交配行为,求偶和交配行为高峰期集中在21∶30—0∶30之间。出土日龄对成虫求偶节律影响不显著,但交配的比例与虫龄密切相关。成虫出土的当天便可交尾,第3日达到交配高峰,7日后交配结束。【结论】筛胸梳爪叩甲成虫求偶及交配高峰期明显,适合性信息素诱杀或干扰防治。【Objective】Bamboo shoot wireworm,Melanotus cribricollis is an important underground pest in bamboo forests in Southern China.To study the courtship and mating behavior of the adults for the development of sex pheromone attractants and their application is of great significance.【Method】In the present study,the characteristics and rhythms of courtship and mating behavior of M.cribricollis adults were observed at night.【Result】The courtship and mating behavior of M.cribricollis adults showed obvious phase characteristics.After entering the dark phase for 90 minutes,the courtship and mating behavior began,with the peak period to be found during 21∶30 to 0∶30.The age of adults excavated from the soil had no significant impact on the courtship rhythm of adults,but the mating ratio was closely related to the age of the adults.Mating behavior was observed on the first day of excavation from the soil,and reached the peak on the third day,then ended seven days later.【Conclusion】The peak period of courtship and mating for M.cribricollis adults is obvious,and thus it is suitable to use pheromone induced killing or mating interference in the management of bamboo shoot wireworms.
