李始叶螨实验种群参数的研究

Studies on the Experimental Population Parameters of Eotetranychus pruni(Oudemans)

在温度17、20、25、30、33℃,相对湿度70±5%条件下,观察了李始叶螨Eotetranychuspruni(Ounde-mas)实验种群的发育起点温度和有效积温,组建了实验种群生命表,估测了种群净增殖率(R0)、内禀增长力(rm)、周限增长率(λ)等生殖力参数。

This papers studied on developmental threshold temperature and effective thermal summation of Eotetranychus pruni （Oundemas） and constructed the experimental population life-table and reproductive table of Eotetranvchus pruni under experiment condition, Main population parameters of this species are gained as follows ： intrinsic rate of increase, net reproductive rate; mean generation time, finite rate. The light shines on and the same circumstance in term in degree of humidity is next, with 25 ℃ even suit the growth of that Eotetranychus pruni.
