摘　　要：为了探明温度对大猿叶虫Colaphellus bowringi Baly的交配行为的影响,在光周期LD12:12,温度22℃,25℃和28℃下,观察了该虫的交配节律、日交配频率、交配持续时间和每日总交配时间。结果表明,该虫的交配节律受温度的影响,22℃下的交配高峰(上午9:00)较25℃和28℃下的交配高峰(上午8:00)推迟了1h。温度对日交配频率和交配持续时间也有明显影响,22℃下日交配频率显著低于25℃和28℃,而交配持续时间则显著长于25℃和28℃。该虫每日总交配时间在这3种温度下变化不明显,而在较低温度下日交配频率的下降可能是由于交配持续时间延长所致。To understand the effect of temperature on mating behavior of the cabbage beetle, Colaphellus bowringi, the mating rhythm, daily mating frequency, mating duration and total mating time per day were investigated at 22℃,25℃ and 28℃ under LD 12：12. The results showed that mating rhythm was influenced by temperature. The daily mating peak at 22℃ delayed one hour compared with at 25℃ and 28℃. Temperature had also a significant influence on daily mating frequency and mating duration. The daily mating frequency at 22℃ was significantly lower than at 25℃ and 28℃; whereas the mating duration at 22℃ was significantly longer than at 25℃ and 28℃. However, the total mating time per day was similar among the three temperatures, suggesting that the decline of mating frequency at lower temperature may be due to the prolongation of mating duration.
