| Outline of Final Research Achievements |
Several Burkholderia strains which are capable of degrading an insecticide, fenitrothion, can establish specific and beneficial symbiosis with some genera of stinkbugs; thereby, making their host insects conferring fenitrothion-resistance to the host insects. The objective of this study was to understand the ecology of Burkholderia symbiotic degraders in a free-living environment.
A field research was conducted in farmer’s fields where stinkbugs (Cavelerius sp.) harboring degraders of Burkholderia species have been identified. The research confirmed that both plant and rhizosphere constitute the environmental reservoirs for stinkbug symbiotic degraders.
Repeated applications of fenitrothion to soil can increase the numbers of degraders. The microcosm experiment with mathematical modeling showed the number of dominant species among the degraders declined with its density increase by fenitrothion applications, which can be explained according to the competitive exclusion principle.
