中文摘要：
【目的】 针对大蜡螟Galleria mellonella L.的性选择行为进行系统观察分析，为大蜡螟性信息素全组分的结构鉴定及利用信息素行为调控技术防控该虫提供依据。【方法】 分别对不同体重、不同日龄和不同交配经历的大蜡螟成虫进行标记，在红光灯下观察并记录大蜡螟雌雄虫的性选择行为。【结果】 在（26±0.5）℃、相对湿度60%、全黑暗条件下，无论雌虫还是雄虫，均倾向于选择与之体重相接近的异性个体进行交配。雌雄成虫均偏向于选择3日龄的异性个体进行交配；雌虫对不同日龄雄虫的选择率大小顺序为3日龄> 5日龄> 1日龄，而雄虫对不同日龄雌虫的选择率大小顺序为3日龄>1日龄> 5日龄。交配经历影响大蜡螟的性选择行为，雌虫优先选择已交配的雄虫进行交配，选择率为74.6%；雄虫也优先选择已交配的雌虫进行交配，选择率为79.4%。【结论】 雌雄虫体重、日龄和交配经历能不同程度的影响大蜡螟的性选择行为，这为进一步研究雌雄交配信号奠定基础
英文摘要：
[Objectives] To identify factors influencing sexual
selection in the greater wax moth Galleria mellonella L.. [Methods] The mate preferences
of weighed and individually marked G.
mellonella adults was observed and recorded under red light lamps during
the scotophase at a temperature of (26 ± 0.5)℃ and a relative humidity of 60%. [Results] Both adult females and males tended to choose
mates that were similar in weight. Furthermore, both sexes preferred to choose
mates that were three-days-old. Female preferences for males of different ages
could be ranked as follows: three-days old > five-days old > one-day old,
whereas male preferences for females of different ages were: three-days old
> one-day old > five-days old. Mating experience affected mate choice
with 74.6% of females preferentially mating with sexually experienced males and
79.4% of males preferentially mating with sexually experienced females. [Conclusion] Weight, age, and mating experience all
affect mate choice in G. mellonella. These results enhance our understanding of the role of sex
pheromones in G. mellonella and
provide a foundation for identifying these compounds and using them to
control this pest.
