Quarantine treatment for mangosteens infested by Bactrocera dorsalis
A joint Thai-Japanese project was carried out to study the possibilities of a cold temperature quarantine treatment for mangosteens (Garcinia mangostana) infested by Bactrocera dorsalis (EPPO A1 pest).
Infested mangosteens were stored at 5, 6 and 7ø C for various time periods. At these temperatures, the probit 9 mortality (99, 9968%) of the B. dorsalis larvae was estimated to occur after approximately 19, 25 and 25, respectively. A confirmatory test showed that not a single larva out of 34 500 survived a cold storage of 13 d at 6ø C.
