中文摘要：
【目的】 为了更好地掌握青杨楔天牛Saperda populnea Linnaeus的生物学特性和有效地提高交配繁殖试验效率，本文研究了青杨楔天牛的生理活性、交配行为，并探究触角的完整性与天牛交配率的关系。【方法】 本试验于适宜交配期（5月）和模拟交配期（9月）两个时期，采用颜色标记法研究青杨楔天牛的性成熟时间，采用木椴饲养法研究观察青杨楔天牛交配行为。【结果】 适宜交配期的青杨楔天牛存活率低，初羽化成虫存在先假死后复苏之后活跃的现象；雌成虫性成熟羽化日龄为2 d，雄成虫为3 d；交配活跃，有交配趋势的29.16%，成功率约为22.18%。模拟交配期初羽化成虫活跃性较高；雌雄性成熟的羽化日龄均为2 d；有交配趋势的16.55%，成功率8.27%。【结论】 在模拟交配期无法展开青杨楔天牛交配繁殖实验研究。触角的完整性对青杨楔天牛交配成功率无明显影响。
英文摘要：
[Objectives] To determine the biological characteristics of Saperda populnea Linnaeus and enhance the breeding efficiency of this species. The physiological activity and mating behavior of S. populnea were studied, including the relationship between antennae and mating rate. [Methods] Sexual maturation time was studied by color-marking individuals, and mating behavior was studied using the basswood feeding method in natural (May), and simulated (September), mating seasons. [Results] The survival rate in the natural mating season was low. Individuals go into torpor after emergence before reviving and becoming active. The age of sexual maturity after the eclosion of female adults was 2 d, and that of male adults was 3d.. 29.16% pairs engaged in mating activity with a success rate of about 22.18%. In the simulated mating season, the activity of the first generation adults was higher, and the age of sexual maturity after the eclosion of male and female adults was 2 d. 16.55% pairs engaged in mating activity with a success rate of about 8.27%. [Conclusion] It was not possible to perform a complete the study of the breeding behavior of S. populnea in a simulated mating season.
