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.

The oriental fruit fly is a major polyphagous insect pest with a worldwide distribution. We investigated the development time, survivorship, longevity and fecundity of B. dorsalis at six different temperatures. We applied the computer programs – TWOSEX-MSChart and TIMING-MSChart - to analyze our data. We obtained the population parameters – adult preoviposition period (APOP), total preoviposition period (TPOP), oviposition days, eggs per reproductive female, first age of survival rate <50%, proportion of male and female individuals, propoortion of N-type individual, and life table parameters (net reproductive rate, intrinsic rate of increase, finite rate of increase, and mean generation time) - and population projection using two computer programs.
