摘　　要：为了明确温度对红色型和绿色型豌豆蚜种群动态变化的影响,在12～32℃ 6个温度条件下研究了2种色型豌豆蚜的生长发育、繁殖和生命表.结果显示：2种色型豌豆蚜在32℃时,不能发育至成虫.2种色型豌豆蚜的净增殖率在12～20℃时均随着温度的增高而升高,在16 和20℃,红色型豌豆蚜的净增殖率显著高于绿色型（P〈0.05）.在24℃时,红色型豌豆蚜的净增殖率显著低于16和20℃ 时同色型（P〈0.05）,而绿色型豌豆蚜显著高于12～20℃时同色型,红色型豌豆蚜的净增殖率显著低于绿色型（P〈0.05）.到28℃时,2种色型豌豆蚜的净增殖率均显著低于12～20℃时同色型.在12～24℃条件下,2种色型豌豆蚜的内禀增长率均随着温度的上升而增加,红色型豌豆蚜的内禀增长率与绿色型相比无显著差异（P〉0.05）.在28℃,红色型豌豆蚜的内禀增长率显著低于绿色型豌豆蚜（P〈0.05）.表明红色型豌豆蚜在较低温度条件下适应性较强,而绿色型豌豆蚜更适合较高温度.In order to clarify the effects of temperature on the population dynamics of the red and green color morphs of pea aphid (Acyrthosiphon pisum ),the development,reproduction,and life cycle of these two pea a-phid color morphs were studied at six constant temperatures ranging from 12 to 32℃.Neither of the two pea a-phid color morphs could develop to adulthood at 32℃.The net reproduction rate (R 0 ),and intrinsic rate of in-crease (rm )of the two color morphs of pea aphid increased with increase in temperature over a range from 12 to 20℃,and the R 0 of the red color morph was numerically higher than that of the green color morph over this range,and significantly higher at 16 and 20℃ (P <0.05).At 24℃,the R 0 of the red color morph was signifi-cantly lower than for the same color morph at 16 and 20℃ (P <0.05),and the R 0 of green color morph was significantly higher than for the same color morph at 12-20℃ (P <0.05),and significantly higher than the R 0of red color morph at 24℃ (P <0.05).At 28℃,the R 0 values of the two color morphs were both significantly lower than for the same color morph at 12 -24℃ (P <0.05).The rm of two color morphs increased with in-creasing temperature over the range 12 to 24℃,and there were no differences in rm between red and green col-our morphs over this range of temperatures (P >0.05).At 28℃,the rm of the red color morph was significant-ly lower than the green color morph (P <0.05).Hence the red color morph was found to be better adapted to lower temperature,and the green color morph better adapted to higher temperature.
