摘　　要：利用信息素黏胶诱捕器和地质统计学等高线绘图技术,分析了面粉成品仓库地中海粉螟的时间空间分布。结果表明,在面粉成品仓库,利用信息素黏胶诱捕器对地中海粉螟具有较好的诱捕效果。试验期间,在面粉成品仓库中累计诱捕到地中海粉螟2 425头,地中海粉螟在仓内非均匀分布,不同月份存在不同的热点区域。全年地中海粉螟在面粉成品仓库主要具有两个分布热点区域,分别为面粉成品仓库和麸皮打包仓库交接的2225-2226处和地台板堆放的2253-2254处。地中海粉螟分布热点区域具有长时间持续存在,并存在向周围扩散虫害的风险。在实际生产中可根据地中海粉螟分布热点区域开展有针对性的防治。The spatial-temporal distribution of Ephestia kuehniella(Zeller)in a flour warehouse was analyzed by using pheromone-baited traps and contour mapping technique of geostatistics.The results showed that pheromone-baited traps had good effect in trapping E.kuehniella,and2425heads of E.kuehniella were caught in the flour warehouse.The results indicated that E.Kuehniella was in nonuniform distribution in the warehouse,and had different distribution hot spots in different months,wherein E.kuehniella in the flour warehouse had two major distribution hot spots all through the year,i.e.2225-2226point at the joint of four warehouse and bran packaging warehouse and2253-2254point of floor decks.The distribution hot spot area of E.kuehniella has characteristics of long-term persistent existence,and had risks of spreading outside.In practical production,targeted prevention measures can be taken according to the distribution hot spots of E.kuehniella.
