Hypothesis
Which secondary sex pheromone component, Z8-14:Ac or Z10-14:Ac, inhibits the attraction of the oriental fruit moth (OFM) to the plum fruit moth (PFM) sex attractants?
Conclusion
The study found that Z8-14:Ac significantly inhibits the trapping of OFM males without affecting PFM males, suggesting its role in maintaining species specificity in sex pheromones.
Supporting Evidence
- Adding Z8-14:Ac to PFM sex attractants reduced OFM male captures by more than 86%.
- Z10-14:Ac inhibited the trapping of both OFM and PFM males when added in higher concentrations.
- GmolPBP2 was identified as the primary OBP responsible for recognizing Z8-14:Ac.
Takeaway
Moths use special smells to find each other, and this study shows that one of those smells can help keep different types of moths from mixing up their signals.
Methodology
The study used electroantennogram assays and field trapping trials to evaluate the responses of moths to different pheromone components.
