摘要

長毛捕值蟎在20、25、30及35℃四定溫及相對濕度在40~65% RH下，以二點葉蟎之卵接於大豆眞葉上，於培養皿內接以長毛捕植蟎，觀察其發育及補食，所得結果簡述如下：在20、25、30及35℃下，長毛捕植蟎完成發育需時分別爲8.54、5.69、5.02及3.77天產卵前期分別爲3.38、2.25、0.86及0.45天；產卵期分別爲27.54、24.13、19.21及12.18天；產卵後期分別爲9.00、15.75、21.14及13.82天二每雌每日產卵分別爲1.75、2.33、3.26及3.88枚；每雌一生產卵分別爲47.62、55.63、62.50及47.18枚；性比(♀:♂)分別爲1.81:1、1.70:1、1.72:1及1.75:1；發育期捕食二點葉螨卵數分別爲8.60、7.49、7.52及9.72枚；每一雌成螨一生捕食分別爲259.69、286.87、280.70及216.90枚。從其生活史及生命表資料；發現長毛捕值蟎之棲羣之發育和繁殖，以35℃似爲較適宜之溫度，而其自然內在增殖率(γm)在此溫度下爲每日每雌增加0.452個體，而棲璽數量加倍僅需時1.534天。

The life history of a predatory mite, Amblyseius longispinosus (Evans) was studied at four constant temperatures of 20, 25, 30 and 35℃ and 40 to 64% relative humidity on primary leaves of soybean, Glycine max Merrill. Eggs of two-spotted spider mite, Tetranychus urticae Koch (Acarina: Tetranychidae), a pest of soybean, were transferred on soybean leaves and A. Ion gispinosus were held on detached leaves at four temperatures for various life history parameter observations. At four constant temperatures of 20, 25, 30 and 35℃, a life cycle of female required 8.54, 5.69, 5.02 and 3.77 days. The preoviposition periods were 3.38, 2.25, 0.86 and 0.45 days; the oviposition periods 27.54, 24.13, 19.21 and 12.18 days, and the postoviposition periods 9.00, 15.75, 21.14 and 13.82 days respectively. The eggs per female per day were 1.75, 2.33, 3.26 and 3.88; average eggs per female 47.62, 55.63, 62.50 and 47.18; the sex ratios (♀:♂) 1.81:1, 1.70:1, 1.72:1 and 1.75:1, respectively. Number of eggs of T. urticae eaten by immature stages of A. longispinosus were 8.60, 7.49, 7.52 and 9.72; number eggs predated on by female adult stage were 259.69, 286.87, 280.70 and 216.90, respectively.
From the life history and life table data, A. longispinosus populations were found to attain their more optimum developmental and reproductive rates at 35℃. The intrinsic rate of natural increase was found to be 0.452 individuals/female/day and the population possessed the capacity to double every 1.534 days.
