Age-Driven Olfactory Plasticity Regulates Oviposition Behavior in Mated Grapholita molesta Females in Response to Pear Fruit Volatiles

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.
