摘　　要：玉米象是我国主要储粮害虫之一,掌握其在某地区的分布及不同储粮场所的差异性对其科学防治具有重要意义。在河南省17个地市的53个粮库、73个粮油加工厂和75个农户进行现场调查,对玉米象在不同地市、不同类型储粮企业的分布特性进行了分析。玉米象在河南省17地市均有分布,在67.7%的调查场所中采集到玉米象,其在不同地市的发现比率值存在差异(p=0.691,s^2=0.034,s^2<p,n=17),符合昆虫种群均匀分布模式。在粮库玉米象的发现比率均值p_(粮油)=0.579,粮油加工厂玉米象发现比率均值p_(粮油加工厂)=0.748,农户玉米象发现比率均值p_(农户)=0.728,粮库玉米象发现比率均值低于粮油加工厂和农户。Sitophilus zeamais Mostchulsky is one of major insect pests of stored grains in China.It is great significance to scientific management to confirm the distribution characteristics in some one provincial region.A survey of S.zeamais collecting was carried out on201stored grain enterprises involved in grain depots,grain and oil processing enterprises,and some farmers where were located in seventeen prefecture-level cities around Henan province.The distribution characteristics of among of the cities and stored grain enterprises were analyzed.The S.zeamais distribution in seventeen prefecture-level cities of Henan province was uniform type.The ratio where the insect was collected units to all investigated enterprises was67.7%〇.The ratio in average,the mean p value(p),was0.691,and variance(s2)was0.034,s2</?(n=17).The statistic data indicated also uniform type of the insect distribution pattern.The p values for grain depots,grain and oil processing enterprises and farmers were0.579,0.748and0.728,respectively.The p value for grain depots was lower than grain and oil processing enterprises and farmers.
