摘　　要：以鼎突多刺蚁为实验对象,研究了热驯化和实验温度对其运动能力的影响。将成年的鼎突多刺蚁随机分成2组,分别置于20℃和30℃下驯化4周。经过驯化的动物分别在20℃或30℃观察、统计它们的运动能力指标——停顿频率、疾跑速度、最大持续运动距离。结果表明:驯化温度、实验温度以及二者的交互作用极显著影响了鼎突多刺蚁的运动速率;经过特定温度驯化的鼎突多刺蚁在该特定温度下的运动能力,相对于经过不同温度驯化而在相同温度下实验个体的运动能力有所提高。上述研究结果支持驯化有益假说。Beneficial acclimation hypothesis （BAH） predicts that the animals acclimated to a particular temperature can enhance their performance and fitness at that temperature, in comparison with those acclimated to other temperatures. Taking Polyrhachis vicina as test object, this paper studied its locomotive performance under effects of thermal acclimation and performance temperature. The P. vicina adults were divided into two groups and acclimated to 20℃ and 30℃ for four weeks, respectively, and after then, their pause frequency, sprint speed, and maximum continuous locomotion distance were measured at 20℃ and 30℃. It was indicated that the acclimation temperature, performance temperature, and their interaction had significant effects on the locomotive performance of P. vicina. The P. vicina adults acclimated to a particular temperature performed better at that temperature than those acclimated to a different temperature, which supported the BAH.
