Age at mating is one of the most important factors that affect mating selection, sexual performance, and fecundity. We studied the effects of mating age on the mating performance and reproductive fitness of Laicharting, a serious pest of poplar and willow, by measuring the time from pairing to successful mating, mating duration, fecundity, hatching probability, and female lifespan. Delayed mating of females and males significantly prolonged the time from pairing to successful mating and the mating duration, but had no effect on the duration of the egg-laying period. Delayed mating of females did not significantly affect fecundity or egg hatching, but significantly prolonged the female lifespan. Although delayed mating of males had a significant negative impact on egg hatching, it had no effect on the lifespan or fecundity of females. These results indicate that delayed mating affects the mating performance of , although it has a limited effect on reproductive fitness. This suggests that delayed mating is unlikely to contribute to the success of mating disruption, when applied to control .
交配年龄是影响交配选择、性行为和繁殖力的最重要因素之一。我们通过测量从配对到成功交配的时间、交配持续时间、繁殖力、孵化概率和雌虫寿命，研究了交配年龄对杨树和柳树的一种严重害虫——光肩星天牛交配性能和繁殖适合度的影响。雌虫和雄虫延迟交配显著延长了从配对到成功交配的时间以及交配持续时间，但对产卵期的持续时间没有影响。雌虫延迟交配对繁殖力或卵孵化没有显著影响，但显著延长了雌虫寿命。虽然雄虫延迟交配对卵孵化有显著负面影响，但对雌虫的寿命或繁殖力没有影响。这些结果表明，延迟交配会影响光肩星天牛的交配性能，尽管它对繁殖适合度的影响有限。这表明，当应用于防治光肩星天牛时，延迟交配不太可能有助于交配干扰的成功。
