The females of Haplogonatopus (Hymenoptera: Dryinidae) are wingless. Thus, the migration ability of adult wasps should be highly restricted. However, passive dispersal of larvae parasitizing their hosts may be possible. In this study we discuss the genetic variation of H. apicalis Perkins and H. oratorius (Westwood) in East Asia, from the perspective of the geographical distribution and the long-distance migration ability of their hosts, using 807 bp of mitochondrial COI gene sequences. Genetic variation of H. apicalis parasitizing Sogatella furcifera (Horváth) was examined on the basis of individuals from western Japan, southern China, and northern Vietnam. High genetic diversity was observed but geographical populations were not recognized. For H. oratorius parasitizing Laodelphax striatellus (Fallén), individuals from the northern and southern coasts of eastern Japan, western Japan, eastern China, and Taiwan were examined. The southern coast of eastern Japan population was discriminated from the other populations, and three core haplotype groups moderately associated with geographical distribution were apparent. However, the population sampled at Hokuriku, located on the northern coast of eastern Japan, was composed of a mixture of haplotypes dominant in other locations, even geographically far separated from China. This may imply the occurrence of the migration pathway of L. striatellus from continental China toward eastern Japan. The results for two parasitoid species can be explained on the basis of the migration ability of the host species.
