The oriental fruit fly is a major polyphagous insect pest with a worldwide distribution. The effects of temperature on stage-specific development were investigated at eight constant temperatures (13.0, 14.4, 16.2, 19.5, 23.8, 27.7, 31.8 and 34.8℃). Stage-specific lower developmental thresholds and thermal constants were determined using linear regression. The lower and higher temperature threshold (TL and TH) were estimated using the Sharpe-Schoolfield-Ikemoto (SSI) model. The daily adult emergence frequency of B. dorsalis was estimated in relation to adult age and temperature. Thermal performance was compared among B. dorsalis populations from different locations in Taiwan.
