Plain Language Summary

The objectives of this study were to determine the timing of female emerald ash borer maturity, that is when she is ready to mate and lay eggs. We dissected females at different ages to determine if they had mature eggs. We also dissected females captured on traps baited with different host volatiles to determine if the level of maturity of a female influenced which host compound she was attracted to. We determined that females appear ready to mate by 8-10 days old, but do not develop mature eggs until after mating and until approx. 18-20 days of age. We also determined that females were more attracted to different host volatiles, depending on how mature they were. We also found that very young virgin females were rarely ever captured on traps baited with the currently used ash host volatiles. This work increases our understanding of reproductive development in this species, and also highlights a gap in our knowledge about what young females are attracted to.
