Outline of Final Research Achievements

Some fenitrothion-degrading bacteria living in soil can transmit to stinkbugs and establish symbiosis with the host stinkbug. We have been clarified the infection route of the degraders to stinkbugs; soil and plans (sugarcane) are their reservoirs. Then we hypothesized that soil microorganisms adapt not only to the soil but also to the body of plants and insects, and in some cases, freely change their niches, to maintain their population in the ecosystems.
To test the hypothesis, we conducted a field experiment and showed that the degraders can migrate relatively easily from soil to soybean plants, but it seems difficult to transmit to the stinkbugs. The non-degraders which is phylogenetically close to the degraders are present widely in agricultural soil.
