摘要: 在室内养虫笼观察并分析松墨天牛Monochamus alternatus在以24 h为周期内的交配行为及其规律。松墨天牛交配行为包括2个步骤:一是雌虫接近雄虫,在其周围活动;二是雄虫抱握雌虫,发生交配行为。交配日节律观察结果显示:松墨天牛在24 h内有2次交配高峰期,10∶00-14∶00和18∶00-24∶00,它在这2个时间段以外很少或几乎不交配。松墨天牛交配行为具有以下特点:普遍存在与同一个体或不同个体的多次交配现象,交配次数为2次(含)以上的松墨天牛个体约占全部个体的77.5%,每次交配时间平均为50 s;除正常雄雌交配外,还会出现雄雄和雌雌交配以及2只雄虫争夺雌虫交配权的现象。图1表1参15Abstract: The mating behavior and characteristics of Monochamus alternatus adults in cages were observed over a 24 h period. Results showed that the mating behavior consisted of two steps:1) the female got close to and moved around the male,and 2) the male caught the female and mated. Mating behavior rhythm within 24 h consisted of two mating peaks at 10∶00-14∶00 and 18∶00-24∶00. Little to no mating behavior occurred outside of these periods. Mating behavior revealed that multiple mating existed universally. Individuals with a mating frequency of 2 times (or more) accounted for 77.5% of all experimental insects,and mating lasted 50 s each time. Apart from the normal male-female mating,male-male mating and female-female mating occurred. In addition,two males sometimes fought for the right of mating with the same female.[Ch,1 fig. 1 tab. 15 ref.]
