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.

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.

오리엔탈과실파리는 대만 우펑에서 채집된 후 누대 사육된 개체들로, 저온에서의 유충과 용의 100% 사망에 필요한 소요일수를 조사하였다. 시험기간 중 실측된 온도는 –4.7, -3.4, -1.0, 0.9, 3.9, 5.8, 7.9도였다. 실험은 시간(일 단위)별로 저온에 처리하였고, 이후 상온으로 이동시켜 개체의 사망여부를 조사하였다. 노출 시간별로 3반복으로 실험하였고, 반복당 20~30 개체를 사용하였다. 각 온도별 유충의 100% 사망소요일수는 1, 3, 7, 6, 10, 10, 34일이었고, 용의 경우 0.25, 4, 9, 7, 10, 18, 30일 이었다.
