Abstract:
[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.
