摘要: 六点始叶螨[Eotetranychussexmaculatus(Riley)]是西双版纳地区为害橡胶树的重要害螨,为研究该螨的主要生物学特性,同时在不同恒温条件下测定了六点始叶螨各螨态的发育历期,并用直线回归法计算出各螨态的发育起点温度和有效积温。结果表明,在18~30℃范围内,六点始叶螨的历期、发育速率和温度间相关性明显,其卵的发育起点温度为(12.32±1.33)℃,有效积温为(62.52±6.69)℃·d;幼螨至成螨的发育起点温度为(9.38±3.30)℃,有效积温为(153.79±33.46)℃·d;全世代的发育起点温度为(9.52±1.70)℃,有效积温为(233.18±26.25)℃·d。为有效开展六点始叶螨的监测预报及综合防治提供科学的依据。

Abstract: Eotetranychus sexmaculatus (Riley) is an important mite pest of rubber tree in Xishuangbanna. To study its principal biological characteristics, developmental durations of Eotetranychus sexmaculatus (Riley) in different stages were studied under a range of constant temperatures. Developmental zero and effective accumulated temperature were calculated with linear models. The results indicated that the relationship between temperature and development rate, each stage fitted well when the temperature was from 18℃ to 30℃. The developmental zero for eggs was (12.32±1.33)℃ and the effective accumulated temperature for eggs was (62.52±6.69)℃·d. The developmental zero from larva to adult was (9.38±3.30)℃ and the effective accumulated temperature from larva to adult was (153.79±33.46)℃·d. The developmental zero of the whole generation was (9.52±1.70)℃ and the effective accumulated temperature of the whole generation was (233.18±26.25)℃·d. The results provided a scientific basis for monitoring and integrated management of Eotetranychus sexmaculatus (Riley).
