Abstract
Larch and pine associated populations of Zeiraphera diniana (Lepidoptera: Tortricidae) differ in a number of heritable traits, but pheromone-mediated cross-attraction occurs between them in the wild. Using a quartet mate choice design (one male and one female of each type per cage) we estimate that, following cross-attraction by pheromones, the subsequent probability of hybridization is approximately 28%. We also examined molecular data, and were unable to distinguish between the races on the basis of 695bp of mitochondrial COI, tRNA-leucine, and COII gene sequence. Both results support earlier field studies suggesting that larch- and pine-feeding populations are host races that hybridize at an appreciable level in the wild. The shared mitochondrial haplotypes we observed are also consistent with ongoing and successful gene flow between the two host races.
