The Oriental Fruit Moth (OFM) (Grapholita molesta) has become a major apple pest in many parts of the country. Broad spectrum insecticides have been the most common form of control. But in recent years insect growth regulators (IGR) have become more accepted as a safer, less environmentally damaging way to control many insect pests including OFM. Some recent studies have shown that methoxyfenozide, an ecdysone agonist, has had some effects on the ability of some adult tortricid moths to emit and respond to their own attraction pheromone. Here we report on the effects this IGR has on OFM emission and attraction and on the sublethal effects methoxyfenozide has on the moth’s fecundity and fertility.
