摘要

本研究以年齡齡期兩性生命表之理論分析南黃薊馬（Thrips palmi Karny）以茄葉飼養在15、21、25、30℃四種溫度下之生命表介量。結果顯示，齡別繁殖值（mχ）、每日繁殖值（fχ5）及齡別繁殖淨值（lχmχ）在25℃下為最高。15、21、25、30℃四種溫度的內在增殖率（r）分別為0.033、0.046、0.157 及0.118 day^(-1)；淨增殖率（R0）以25℃的18.6粒卵/雌成蟲為最高。平均世代時間（T）隨溫度的升高而遞減，然而30℃僅較25℃少1天。本文也以Jackknife方法估算內在增殖率、終極增殖率 （λ）、淨增殖率及平均世代時間的平均值及標準機差（standard error）。本文也利用生命表介量提出南黃薊馬田間管理策略上的建議。

The life table parameters of Thrips palmi Karny were determined at four constant temperatures, 15, 21, 25, and 30°C, on eggplant leaves for three generations. The results indicated that the age-specific fecundity (mχ), the daily fecundity (fχ5), and the age-specific maternity (lχmχ) were highest at 25°C. The intrinsic rate of increase (r) rose from 0.033 day-1 at 15°C to between 0.046 and 0.157 day-1, then dropped to 0.118 day^(-1) at 21, 25°and 30°C, respectively. The net reproductive rate (R0) was highest at 25°C at 18.6 eggs/individual. The mean generation time (T) shortened gradually from 15 to 30°C, but was only one day shorter at 30°C than at 25°C. The standard error of r, λ, R0, and T were estimated by using the Jackknife method. Accordingly, the management strategy for T. palmi was suggested based on this study.
