Cydia molesta (Busck) (Lep. Tor.) is a polyphagous pest mainly damaging peach and pome fruit-trees. The aim of the research is to study the host-plant location behaviour of virgin and mated females in a Y-tube olfactometer. This work introduces the first investigation on semiochemically mediated host location behaviour and adult conditioning of female C. molesta. The results show that both naive and experienced virgin females respond to volatiles emitted by peach (fruit and shoots) and pear (fruit and shoots) but only at high light intensity (3500 lux). Results provide a first indication of the habitat location strategy of this important pest
