We found that after the parasitoidOpius lectus has arrived on a fruit infested by eggs or early-instar larvae of its tephritid hostRhagoletis pomonella, the following stimuli act to retain it and elicit antennal tapping and oviposition probes: unidentified fruit chemical components; characteristic fruit shape, size and color; andR. pomonella oviposition-deterring pheromone. This is the first demonstration of an oviposition-deterring pheromone in a phytophagous insect serving as a kairomone to one of its parasitoids.O. alloeus, a parasitoid of lateinstar larvae ofR. pomonella, was not influenced by the pheromone. Possible use of the pheromone for management ofO. lectus in a multifacetedR. pomonella suppression program is discussed.
