Riptortus pedestris is one of economically important insect pests in soybean fields. The study was conducted at six constant temperatures of 15.8, 19.7, 24.0, 27.8, 32.6 and 35.5℃. We investigated the biological traits of R. pedestris adults. R. pedestris adults survived at all temperatures tested but female did not oviposit under 15.8℃. The longevity of R. pedestris male was longer than that of female. Oviposition model was constructed using nonlinear functions and the number of eggs produced by a cohort of females was estimated in relation to constant temperature and adult age. The life table parameters in relation to temperature were analyzed.
