Investigation of population genetic structure in indigenous natural enemies

To develop conservation biological control programs, microsatellite DNA markers were developed and population genetic structures were analyzed in two indigenous natural enemy species. The aphidophagous gall midge, Aphidoletes aphidimyza, showed no spatial autocorrelation patterns, and different mitochondrial haplotypes were widely spread and found in most of population, indicating dispersal range in A. aphidimyza was beyond a single field. For predatory mite, Neoseiulus womersleyi, showed clear population structure in a tea field ; the inhabiting range of N. womersleyi was expected within a 100m diameter.
