摘　　要：亚洲玉米螟Ostrinia furnacalis(Guenée)为制约当前新疆玉米高产稳产最重要的害虫之一。为全面准确摸清亚洲玉米螟在新疆各玉米主产区的种群时空动态情况,本文利用2015年和2016年田间亚洲玉米螟发生数量的系统监测数据,结合2015年-2023年气象数据测算了亚洲玉米螟近9年的理论发生世代数。结果表明,北疆伊犁州、乌鲁木齐市以及南疆喀什地区亚洲玉米螟均出现了3个发生世代(成虫、卵和幼虫高峰期),且这3个玉米主产区连续9年的热量资源均已满足一年发生3代所需的积温条件,而北疆昌吉州东部、东疆哈密地区则呈现出2个发生世代(成虫、卵和幼虫高峰期)。这说明,新疆荒漠绿洲生态区亚洲玉米螟已由以往“一年2代区”逐步向“2、3代混生区”转变,其中部分区域已稳定演变为3代区。The Asian corn borer,Ostrinia furnacalis(Guenée),is a significant pest limiting stable and high corn yields in Xinjiang.To accurately assess the spatiotemporal dynamics of O.furnacalis populations and improve precision pest control,this study analyzed the occurrence dynamics and theoretical generations of O.furnacalis using systematic field monitoring data from 2015 to 2016 and meteorological data from 2015 to 2023.The results showed that there were three peak periods corresponding to adults,eggs,and larvae in the Ili prefecture,Urumqi city,and Kashi region of northern Xinjiang.The analysis of heat resource data confirmed that these regions consistently met the accumulated temperature requirements for three annual generations over the past nine years.Conversely,regions such as eastern Changji prefecture in northern Xinjiang and Hami city in eastern Xinjiang exhibited two peak periods,indicating the occurrence of only two generations annually.In summary,the desert oasis ecological zones of Xinjiang are transitioning from a traditional“two generation area per year”for O.furnacalis to a“mixed zone of two and three generations”,with an increasing prevalence of stable“three-generation areas”.
