| 摘 要： | 苹果黄始叶螨以雌成螨在苹果根际土壤中群集成团结网越冬。翌年芽萌动到花序分离至初花期是雌螨出蛰盛期。田间种群数量消长是:一年中的4月中下旬～5月中旬;8月中下旬～9月下旬出现两次高峰期。实验种群生命表结果是:净生殖率(R_o)为9.9107,世代平均周期(T)为25.0961、周限增长率(入)为1.0956,内禀增长率(r_m)为0.09139。

| Abstract: | Apple Yellow mites (Eotetranychus'sp.) might net and overwinter through female adults in group in the soil among rootlets of the apple tree and most of them wake when the apple treeggerminates and inflorescenes appear. The quantity of the varieties groups grow and decrease from mid-late-April to mid-May from mid-late-Aug to the end of Sep. The experirmental varieties life list show as follows: the net reproduction rate (R_o) is 9.9107; the average generation life eirele (T) is 25.0961; the growing quantity rate per Unit time (λ) is 1.0956 and the catpacitv of growing rate (rm) is O.09139. |
