为酢浆草岩螨的综合治理提供理论依据，通过设置24℃、27℃和30℃不同温度处理，采用水培红花酢浆草饲养酢浆草岩螨，测定该螨各虫态的发育历期、寿命、产卵量和产卵期等生命表主要参数，以及种群内禀增长率等种群动态参数。结果表明：随着温度的升高，酢浆草岩螨各虫态的发育历期呈逐渐缩短的变化趋势，30℃与24℃相比，完成1个世代缩短4．29 d，卵发育历期缩短1．47 d。日均产卵量和总产卵量随温度的升高而增加，30℃时分别为（69．50±3．45）粒和（5．65±0．36）粒，而24℃时分别为（33．67±1．39）粒和（2．13±0．12）粒。产卵期和寿命则随温度的升高而缩短，30℃时酢浆草岩螨的产卵期和寿命均最短，分别为（12．30±0．83）d 和（14．18±0．75）d，24℃时分别为（15．78±0．61）d 和（18．00±0．56）d。内禀增长率和净生殖率均随温度的升高而增大，24℃、27℃和30℃分别为0．1397、0．1725、0．2349和43．9333、29．0666、20．0200。种群加倍时间和平均世代周期均随温度的升高而减小。高温有利于酢浆草岩螨的实验种群的增长。
為酢漿草巖螨的綜閤治理提供理論依據，通過設置24℃、27℃和30℃不同溫度處理，採用水培紅花酢漿草飼養酢漿草巖螨，測定該螨各蟲態的髮育歷期、壽命、產卵量和產卵期等生命錶主要參數，以及種群內稟增長率等種群動態參數。結果錶明：隨著溫度的升高，酢漿草巖螨各蟲態的髮育歷期呈逐漸縮短的變化趨勢，30℃與24℃相比，完成1箇世代縮短4．29 d，卵髮育歷期縮短1．47 d。日均產卵量和總產卵量隨溫度的升高而增加，30℃時分彆為（69．50±3．45）粒和（5．65±0．36）粒，而24℃時分彆為（33．67±1．39）粒和（2．13±0．12）粒。產卵期和壽命則隨溫度的升高而縮短，30℃時酢漿草巖螨的產卵期和壽命均最短，分彆為（12．30±0．83）d 和（14．18±0．75）d，24℃時分彆為（15．78±0．61）d 和（18．00±0．56）d。內稟增長率和淨生殖率均隨溫度的升高而增大，24℃、27℃和30℃分彆為0．1397、0．1725、0．2349和43．9333、29．0666、20．0200。種群加倍時間和平均世代週期均隨溫度的升高而減小。高溫有利于酢漿草巖螨的實驗種群的增長。

Hydroponic Oxalis corymbosa was used to breed T.harti under three tested temperature (24℃,27℃ and 30℃),different insect state development period,longevity,egg laying amount,egg laying period and other major life table parameters of the T.harti,and the intrinsic population dynamics parameters of population growth rate were tested in this article,so as to provide a theoretical reference for comprehensive treatment of T.harti.Results:With the increase of temperature from 24℃ to 30℃,each state development period of T.harti shortened.When temperature was 30℃,if it would complete a generation,4.29 d was shortened,1.47 d was shortened during egg calendar period.With the rise of temperature,average daily spawning eggs and total quantity increased.They were (69.50 ± 3.45)and (5.65±0.36)grains when temperature was 30℃.They were (33.67± 1.39)and (2.13±0.12)grains when temperature was 24℃.With the increase of temperature,the spawning period and life period were all shortened.They were all the shortest when the temperature was 30℃.The spawning period were respectively (12.30±0.83)d and the life period was (14.18±0.75)d.When the temperature was 24℃, the spawning period was (15.78±0.61)d and the life period was (18.00±0.56)d.Intrinsic growth rate and net reproductive rate increased with the increase of temperature.Intrinsic growth rate were 0.1397 (24℃),0.1725 (27℃),0.2349(30℃)and net reproductive rate were 43.9333 (24℃),29.0666 (27℃), 20.020 0(30℃)respectively.Population doubling time and average generation cycle decreased with the increase of temperature.Higher temperature is beneficial for the growth of sorrel T.harti experimental population.
