Abstract
Scirtothrips dorsalis Hood is one of the most important pest thrips on mango Mangifera indica L., trees cultivated in Okinawa Prefecture, southwestern Japan. Scirtothrips dorsalis has two strains, C and YT, but there is little information about their geographical distribution and composition ratio on mango in Okinawa Prefecture. In this study, we collected S. dorsalis infesting young leaves of mango from islands in Okinawa Prefecture and analyzed their strain based on a multiplex-PCR method. Among 80 localities investigated in Okinawa Prefecture, the number of localities with only strain C, both strains or only strain YT were 68 locations, 11 locations and 1 location, respectively. The composition ratio of strain C among the localities investigated, in which both strains were found, was high（77–95%）in 8 locations and low（5–29%）in 3 locations. These results show that the main strain of S. dorsalis infesting mango in Okinawa Prefecture is strain C.
