Empirical studies demonstrate a negative relationship between body size and temperature [i.e. the temperature‐size rule (TSR)] and a positive relationship between body size and development time (a trade‐off). However, many exceptions are also reported. The present study tests the two relationships in a tropical population of the Asian corn borer Ostrinia furnacalis under a wide range of temperatures from 18 to 31 °C. The results show that larval time is decreased significantly and pupal weight is increased significantly with an increasing rearing temperature, exhibiting the reverse‐TSR. Growth rate is positively correlated with temperature. The relationships between body size and development time among individuals show a negative slope (i.e. pupal weight tends to decrease with increases in development time). Females are significantly larger than males at all temperatures, showing a female‐biased sex size dimorphism. It is also found that development time and pupal weight vary greatly among individuals, particularly at lower temperatures. The results of the present study demonstrate a reverse‐TSR associated with a negative relationship between larval development time and pupal weight in a tropical population of O. furnacalis.

与 Ostrinia furnacalis 热带种群幼虫发育时间和蛹体重负相关的反向温度大小规则

实证研究表明，体型与温度之间存在负相关关系 [即温度-大小规则 (TSR)]，而体型与发育时间之间存在正相关关系（权衡）。但是，也报告了许多例外情况。本研究在 18 至 31 °C 的广泛温度范围内测试了亚洲玉米螟的热带种群中的两种关系。结果表明，随着饲养温度的升高，幼虫时间显着减少，蛹重显着增加，表现出反向TSR。生长速度与温度呈正相关。个体之间的体型和发育时间之间的关系显示出负斜率（即蛹重量随着发育时间的增加而降低）。在所有温度下，雌性都明显大于雄性，显示出偏向雌性的性别大小二态性。还发现个体之间的发育时间和蛹重量差异很大，特别是在较低温度下。本研究的结果表明，在 O. furnacalis 热带种群中，反向 TSR 与幼虫发育时间和蛹重量之间的负相关。
