摘　　要：为了深入了解胡杨春尺蠖(Populus euphratica Apochemia cineraius Erschoft)虫害的发生期规律,以新疆叶尔羌河流域胡杨林分布区为研究区,结合2001-2015年的胡杨春尺蠖活动期遥感数据温度和实地调查虫情信息,基于有效积温法则,预测春尺蠖发生期,从而确定最佳防治时间。结果表明:(1)春尺蠖羽化之后各虫态发生时,环境温度远远超过发育起点温度,因此各虫态的发生时间大大缩短,符合新疆春尺蠖发生时间周期短的现象;(2)借助有效积温模型,可知二龄虫发生时春尺蠖虫卵孵化进入始末期,且春尺蠖四龄食叶虫基本没有发生,因此春尺蠖最佳防治时间是幼虫的二龄虫。The Populus euphratica distribution in Yarkant River Basin was taken as the research area.Populus euphratica Apocheima Cinerius Erschoff was used as the research object.Remote sensing data of Populus euphratica were extracted by remote sensing technology and remote sensing products such as MODIS from 2001 to 2015.Based on the effective accumulated temperature law and the prediction of the occurrence period of spring ridges,the optimal control time was determined,which provided a scientific basis for further research on the occurrence time,occurrence rules,hazard degree and time distribution of Populus euphratica in the Yarkant River Basin.The results showed as follows:(1)When the parasitic states occurred after the emergence of the spring scales,the ambient temperature far exceeded the developmental start temperature,so the occurrence time of each state of the parasites was greatly shortened,which was consistent with the short time-period phenomenon of the spring scales of Xinjiang.(2)Accumulation temperature model shows that when the second instar larvae hatch into the beginning and the end of the hatching period,and the four-instar leaf-foot instar larvae did not occur,so the best control time larvae are the second instar larvae.
