The results showed that the developmental threshold of egg, larva and immature periods was 12.67, 13.86 and 13.53℃, respectively. It revealed parabola relationship between temperature and both generation survival and finite increase rates. According to the corresponding parabola functions, the optimal temperature for survival and population increase was 30.2 and 33.7℃, respectively, and the optimal temperature range for growth and development of C. maculates was between 30 and 34℃.

结果表明：四纹豆象卵期、豆内幼虫及蛹期、未成熟期发育点温度分别为12.67，13.86和13.53℃；温度与世代存活率及周限增长率均呈二次抛物线关系，根据相应抛物线方程可知，四纹豆象理论最适生存温度和最适种群增长温度分别为30.2℃和33.7℃，其生长发育繁殖的最适温区为30～34℃。
