| 摘 要： | 在温度(25±2)℃、RH(75±5)％、光照周期14(L)∶10(D)的条件下,研究以木薯(Manihot esculenta)、橡胶(Hevea auyanensis)、木瓜(Chaenomeles sinensis)、变叶木(Codiaeum variegatum)和芒果(Mangifera indica)5种植物叶片饲养木薯单爪螨(Mononychellus mcgregori)对其生长发育及繁殖的影响.结果表明:不同植物对木薯单爪螨生长发育及繁殖存在显著影响.木薯单爪螨取食木薯和橡胶叶片能完成世代发育,以木薯饲养,其F0代发育历期8.10d,F1代发育历期8.45 d；以橡胶饲养,其F0代发育历期8.45 d,F1代发育历期10.95 d.木薯单爪螨取食木瓜、变叶木和杧果新鲜叶片不能完成世代发育,F0代仅发育至幼螨期,分别为3.70、1.80和1.60 d；后代性比以木薯最大,F0和F1代分别为80.80％和88.50％,橡胶分别为80.20％和80.60％.木薯单爪螨在不同寄主上的单雌产卵量以橡胶最高,F0和F1代分别为25.8和29.8粒,木薯次之,分别为18.6和26.2粒,在木瓜、变叶木和芒果上只有木薯单爪螨F0代产卵,分别为1.2、0.98和0.6粒；成螨寿命以橡胶上成活最长,F0和F1代分别为19和20d,木薯分别为17和18d居次；在木瓜、变叶木和芒果上,木薯单爪螨成螨仅分别成活5.5、5和5d.综上所述,木薯单爪螨不仅对木薯产生危害,且极有可能转移为害热带经济作物橡胶,对橡胶产业的发展存在一定的安全隐患.
