| Outline of Final Research Achievements |
This study investigated recent kin selection theory considering kin competition, by the analysis of kin structure in populations of the social spider mite, Stigmaeopsis miscanthi (Saito), which infests Japanese pampas grass (Miscanthus sinensis Anderson) leaves and shows geographic variation in male-male aggressiveness. I collected mites from six populations with high, low and intermediate male-male aggressiveness from the southern and central Ryukyu regions and the Kyushu region. Mites from each population were sampled from three different units: nest of the mite, root and stand of the host plant. DNA was then extracted from each individual (N=192) and RAD-seq carried out using Illumina HiSeq 2500, with the cooperation of the Nodai Genome Research Center. At present, sequence data is being analyzed to assess kin structure.
