The Oriental Fruit Moth (OFM) (Grapholita molesta Busck) 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 (Intrepid), an ecdysone agonist, has had some negative effects on the sex pheromone communication between adult moths of some tortricid species. Here we report on the effects of methoxyfenozide on OFM attractiveness and responsiveness in wind tunnel studies.
