| Popis: | Mating disruption using synthetic sex pheromones is an effective pest-control method to prevent the evolution of insecticide resistance. Although the sex pheromone of the yellow peach moth Conogethes punctiferalis (Guenee) (Lepidoptera, Crambidae) has already been identified and artificially synthesized, mating disruption in the field has been less successful than expected. Such ineffectiveness may be caused by genetic variation in the attractiveness of the sex pheromone across moth populations. To evaluate this possibility, we evaluated the genetic population structure of this species across 10 populations in Japan. We found that two clades were present at the mtDNA COI region, each clade was sympatrically distributed, and no genetic structure was detected among the populations. In addition, the frequencies of the two clades did not differ between the samples in pheromone traps using two types of blend and those hand collected from infested fruit. Our mating experiment revealed random mating between the two clades. Our results strongly suggest that the genetic variation in the attractiveness of the sex pheromone is minimal and symmetrical gene flow likely occurs between the clades in the field. |
