Key Points

This research investigates how age-related changes in olfactory perception affect the egg-laying behavior of mated Grapholita molesta females.
Examined the olfactory responses of Grapholita molesta females to pear fruit volatiles across different ages.
Assessed oviposition behavior in relation to exposure to these volatiles.
Younger females showed a stronger attraction to pear fruit volatiles than older females.
Oviposition rates were higher in younger females exposed to these volatiles compared to older females.
