| Outline of Final Research Achievements |
Two strains of Kanzawa spider mite (KSM) - the white scar strain (W-strain) and the red scar strain (R-strain) - induce distinct defense response in the same Phaseolus leaves. In this study, we carried out RNAseq-based transcriptome analysis for mRNA of R-strain and W-strain on kidney bean plants (P. vulgaris) to identify KSM genes expressed specifically in either R-strain or W-strain. Of particular interest is the fact that some genes involved in the detoxification system in KSMs were expressed higher in R-strains than in W-strains. Some of detoxification enzyme activities were higher in R-strain than in W-strains as well. Further we investigated whether the differences in detoxification affect the tolerance of acaricides. R-strain showed less mortality than W-strain when they were treated with 3 out of 5 acaricides, suggesting that R-strain latently possesses higher detoxification ability than W-strain.
