昆虫的体温通常由环境温度决定。因此，大多数构成行为模式基础的生化和生理过程都依赖于温度。交配持续时间也取决于温度，所以温度应该会影响精子传递和雌性再次交配的频率。在绿豆象（Callosobruchus chinensis）中，我们发现环境温度与交配持续时间、精子传递以及精子传递持续时间之间呈负相关。较低温度（17℃）下雌性再次交配的频率低于其他温度（25℃和33℃）。对这些结果的生理和行为意义进行了讨论。在33℃时射出的精子数量明显少于17℃；结合雌性针对雄性的拒绝行为强度，讨论了温度对精子传递的影响。（c）2008爱思唯尔有限公司。保留所有权利。
Insect body temperature is usually determined by ambient temperature. Therefore, most biochemical and physiological processes underlying behavioural patterns are temperature dependent. Mating duration is also dependent on temperature, and therefore temperature should influence on sperm transfer and female remating frequency. In the adzuki bean beetle, Callosobruchus chinensis, we found negative relationships between ambient temperature and mating duration, sperm transfer and sperm transfer duration. Female remating frequency at lower temperature (17 degrees C) was lower than at other temperatures (25 degrees C and 33 degrees C). The physiological and behavioural significance of these results is discussed. The number of ejaculated sperm was significantly lower at 33 degrees C than at 17 degrees C; the effect of temperature on sperm transfer is discussed in relation to the intensity of female refusal behaviour directed against males.
