Phytosanitary cold treatments were tested for Bactrocera invadens Drew, Tsuruta, and White and Bactrocera zonata (Saunders) using comparisons with Ceratitis capitata (Wiedemann). Oranges were infested by puncturing holes in the peel and allowing tephritids to oviposit in the holes. The treatments were initiated when the larvae reached late third instar because previous research had shown that stage to be the most cold tolerant for all three species. Results show that B. invadens is not more cold tolerant than C. capitata and B. zonata at 1.0±0.1°C and lend support to the use of C. capitata cold treatment schedules for B. invadens. It cannot be concluded that B. zonata is not more cold tolerant than C. capitata.
