| 摘 要： | 在5种不同温度条件下研究了大豆蚜有效积温、发育起点温度、繁殖力等生物学特性。结果表明,大豆蚜各虫态的发育历期随着温度的升高而显著缩短,若虫发育明显受到低温抑制。10℃下发育历期最长为22.08d,15、20、25、30℃分别为14.04,10.67,9.92和6.71d。相对低温同时也抑制大豆蚜繁殖能力,10℃下平均产仔量和日产仔量均为最小,分别为15.73头和1.23头/d。20和25℃下大豆蚜繁殖力较强,平均每天产仔量分别为27.87和27.36头。通过直线回归分析,得出大豆蚜1龄若虫发育起点温度为2.026 8℃,有效积温为38.421 6日度,大豆蚜世代发育的起点温度为1.658 7℃,有效积温为202.787 9日度。

| Abstract: | The biological characteristics of Aphis glyicines Matsumura including available accumulation temperature,starting development point and fecundity etc,were studied in 5 different temperatures.The results showed that increased temperature shortened developmental duration significantly and the low temperature suppressed development of nymph.The longest developmental duration was 22.08 days in 10℃.In 15℃,20℃,25℃ and 30℃ the developmental duration were 14.04,10.67,9.92 and 6.71 days respectively.Low temperature also suppressed the reproduction of Aphis glyicines Matsumura.The least average and daily fecundity were 15.73 and 1.23 at 10℃,and the higher average fecundity were 27.87 and 27.36 at 20℃ and 25℃ respectively.Linear equation regression analysis showed that the temperature of the starting development point of the 1st instar was 2.026 8℃,the available accumulation temperature was 38.421 6 degree-days.The figures of which for the total period were 1.658 7℃ and 202.787 9 degree-days. |
