【摘要】 观察了养虫笼中松墨天牛Monochamus alternatusHope的交配和产卵行为。描述了雌、雄虫在交配过程中的多种行为,雌、雄虫间的交配时间可持续23~540 min,平均约200 min;有重复交配现象,重复交配次数可达2~18次;每次交配持续时间为2~100 s。雌虫背负雄虫,边取食边产卵;也可脱离雄虫单独产卵。雌虫在寄主枝条上咬槽产卵,通常日产卵1~2粒,最多3粒。产卵期的长短和产卵量的多少取决于雌虫个体寿命的长短。更多还原

【Abstract】 The mating and ovipositing behavior of Monochamus alternatus was observed in a cage of insect room.The pair-bond could involved repeated copulations(2～18) and each copulation lasted 2 to 100 sec.The minimum and maximum duration for pair-bond was 23 and 540 min.After the copulation,the female could oviposit and eat with the male on top,or oviposit alone.The females gnawed at the bark surface and oviposited on it.One female usually laid 1～2(at most 3) eggs per day.The number of eggs laid by one female is depended upon the longevity of the individual.更多还原
