[Objectives]  To determine the effect of temperature on the development and reproduction of laboratory populations of Stethoconus japonicus. [Methods]  The developmental duration, survival rate, fecundity and population parameters of S. japonicus feeding on Corythucha ciliate, were investigated in an artificial climate chamber at a range of temperatures (15, 20, 25, 30 and (35±1) ℃. [Results]  The average duration of various developmental stages of S. japonicus shortened as the temperature increased from 15 to 35 ℃. S. japonicas required just 84.35 d to complete its life cycle at 15 ℃, but 1 985 d at 35 ℃. The survival rate of eggs, nymphs, egg-adults, pre-laying stages and a complete generation, of S. japonicus, first increased, then decreased, with increasing temperature. Survival was highest at 25 ℃, the developmental starting temperature of a complete generation was 10.59 ℃, and the effective accumulated temperature was 502.48 day- degrees. The adult life span and female laying period gradually shortened with increasing temperature. The life span of females was longer than that of males. The average number of eggs laid per female was highest at 25 ℃ (218.36), and the lowest at 35 ℃ (47.620). The highest population trend index of S. japonicus was I=18.01 at 25 ℃, which was 2.05 times higher than that at 20 ℃, and 7.97 times higher than that at 30 ℃. The optimal temperature for nymph development, survival, adult reproduction and population growth was 25 ℃. These results provide a basic reference for the captive breeding of S. japonicus feeding on C. ciliata. [Conclusion]  The most suitable temperature range for population growth of S. japonicus, in terms of developmental duration, survival rate, developmental rate, longevity and fecundity, is 25-30 ℃.
