Outline of Final Research Achievements

In order to conserve and to enhance the capacity of phytoseiid mites as native natural enemies, population genetic structure of them were investigated by using microsatellite DNA markers. In an organic tea field and peach orchards, clear population structure was detected, suggesting they inhabit within narrow range. In contrast, genetic uniformity was observed in chrysanthemum fields. These results suggest that their dispersal can be enhanced by artificial disturbance.
