Abstract

在 20、25、30 及 35℃ 及 40-65% 相對濕度下，以大豆初葉飼育二點葉蟎（ Tetranychu urticae （Koch），雌蟎總發育期分別為 21.34、11.73、7.59 及 7.28 天；產卵前期分別為 2.14、0.75、0 及 0.44 天；產卵期分別為 27.43、26.00、1 0.9 及 9.33 天；每日每雌產卵量分別為 3.39、5.06、10.42 及 6.44 枚；每雌一生產卵量分別為 86.86、130.52、112.2 及 61.56 枚；雌雄性比例（♀ / ♂）分別為 2.38、2.25、1.44 及 1.65 。又根據生活史之各項資料列其生命表，從而計算出在某溫度下之繁殖力：其淨生殖率（Net reproductive rate , RO 分別為 36.81、64.32、49.91 及 22.66 ；世代平均日數（Mean generation time , T）分別為 30.82、18.42、9.78 及 9.54 天；自然內在增殖率（Intrinsic rate of natural increase , rm）分別為 0.117、0.226、0.400 及 0.327；增殖率極限（Finite rate of increase, λ）分別為 1.124、1.254、1.492 及 1.387 ；棲群加倍所需日數（Days for population to double）分別為 5.92、3.07、1.73 及 2.12 天。在相較之下， 30℃ 似為二點葉蟎發育及繁衍之最適溫。 The life history of Tetranychus urticae (Koch) (Acarina : Tetranychidae) was determined at four constant temperatures of 20, 25, 30 and 35℃ and 40-65% RH. on primary leaves of Glycine max Merrill. At these temperatures one life cycle required 21.34, 11.73, 7.59, and 7.28 days; preoviposition periods 2.14, 0.75, 0 and 0.44 days; the average oviposition periods 27.43, 26.00, 10.90 and 9.33 days. The eggs per female were 86.86, 130.50, 112.20 and 61.56; the sex ratio (♀ / ♂) were 2.38, 2.25, 1.44 and 1.65, respectively. They provided the data necessary to construct life tables of T. urticae. Populations attained optimum growth and reproductive rate of natural increase and finite rate of increase were the highest among the calculated increase rates while the shortest generation time and days for population to double were attained. At temperatures of 20, 25, 30 and 35℃, the net reproductive rate (Ro) of T. urticae were 36.81, 64.32, 49.91 and 22.66, respectively ; while the mean generation times (T) took 30.82, 18.42, 9.78 and 9.54 days; the intrinsic rates of increase were 0.117, 0.226, 0.400 and 0.327; the finite rates of increase were 1.124, 1.254, 1.492 and 1.387; the days for population to double took 5.92, 3.07, 1.73 and 2.12 days, respectively.
