摘　　要：根据东方真叶螨在２０℃、２５℃、３０℃、３５℃，ＲＨ７５％一９５％条件下，以橡胶叶片为食料的发育与繁殖情况，分析了温度对东方真叶螨发育与繁殖的影响，卵、幼螨、前若螨、后若螨、全世代的发育历期及成螨寿命与温度的关系分别为：ｙ后若＝１９．４２８５一１．２３５９ｔ＋０．０２１５ｔ（Ｒ＝０．９９７３）ｙ全世代＝１０８．４６２５一６．１４２５ｔ＋０．０９６９ｔ２（Ｒ＝０．９９９４）ｙ寿命＝４２．９５１一１．０４９４ｔ。在上述温度中，世代平均历期分别为２４．３９±０．８２天，１５．４１±０．６１天，１１．４５±１．２２天和１２．１６±０．８２天，以３０℃为最短，雌螨平均产卵量分别为２１．２４±１０．４４粒，２６．２±１１．０７粒，２４．０９±７．９１粒，２１．４２±１０．６粒。２５℃时产卵量最多。２５一３０℃为东方真叶螨发育与繁殖的最适温度。根据有效积温推算。Eutetranychus orientalis(Klein)was determined in relation of development and re-production on the leaves of Hevea brasiliensis under various constant temperatures of 20℃,25℃,30℃ and 35℃,and RH 75%一90%。The effect of temperature on the spider mite wasanalyzed in respect of the development duration of egg,larva,protonymph, deutonymph andacomplete generation,the adult longevity.At 20℃ ,25℃,30℃ and 35℃,one generation wascompleted in respective days of 24.39±0. 82, 15.41±0.61,11.45±1.22 and l2.16±0. 82,and female adults each laid eggs of 2l.24±10. 44, 26.20±ll.27,24.09±7.9l and 21.42±10. 60. The optimum temperatures for development and propagation of this spider mite werefound in a range between 25℃and 30℃。 Based on the effective cumulative temperature,thespider mite is estimated to propagate 21一22 generations per annum in Hainan island.
