Bactrocera latifrons (Hendel) is believed to have originated in Southeast Asia but has invaded Hawaii and most recently East Africa. This insect has also been recorded on Okinawa Island, the far south of Kyushu Island, Japan. To assess the overwintering ability of B. latifrons adults, survival at constant temperatures (8, 10, 12, 14, 15 °C) and under fluctuating thermal regimes (FTRs) was investigated. At 14 or 15 °C, more than 30 % of females survived for 90 days. Time required to kill 95 % of B. latifrons at 8 °C was estimated to be 13 days; at 10 °C, 29 days; and at 12 °C, 38 days for females, and 8, 17, and 24 days at the same above temperatures, respectively, for males, suggesting low cold tolerance of this species. The results show that females survive cold temperatures better than males. Under an FTR of 11 °C (22 h)/20 °C (2 h) (average 11.8 °C) survival of females drastically increased compared to that at a constant temperature of 12 °C, whereas the survival of males increased slightly. Survival under FTRs indicates that adult B. latifrons may not overwinter in the north of Tanegashima Island, located 30 km south of Kyushu Island, Japan.
