暗黑鳃金龟(虫甲)(Holotrichia morosa Waterhouse)、大黑鳃金龟(虫甲)(H·oblita Faldermann)的幼虫是山东花生产区主要地下害虫之一.本文通过田间调查资料,测定和分析了暗黑鳃和大黑鳃金龟?幼虫的空间分布模式.测定表明,暗黑鳃金龟?幼虫较明显地符合嵌纹分布.大黑鳃金龟(虫甲)幼虫的基本分布型呈小群体分布—聚集分布.因此,田间调查此两种害虫的方式可采取“Z”字形九点取样法,调查面积共9平方市尺,即1平方米为宜. The Holotrichia morosa Waterhouse and H. oblita Faldermann larvae are one of the major underground pests in the flower production area of ​​Shandong Province.Through the field investigation data, Dark gills and black gills beetle larvae of the spatial distribution patterns.Analysis showed that the dark gill beetle? Larvae more obviously in line with the embedded pattern distribution. Larix giganticola (larvae) larvae of the basic distribution of small population distribution - aggregation distribution Therefore, the field investigation of these two kinds of pests can take the “Z” shape nine sampling method, survey area a total of 9 square feet, that is, 1 square meter is appropriate.
