麦红吸浆虫在麦株之间活动高度的分析

Analysis of the Height of Wheat Midge Activities between Wheat Plants

为了研究麦红吸浆虫在麦株间的活动高度,对麦株间不同高度上的麦红吸浆虫数量进行调查,并运用地学统计学的方法,分析其在高度方向上的集中分布点和主要分布区域。诱捕调查结果表明,麦红吸浆虫成虫活动高度的2个峰值为距地面15 cm和45 cm,分别是其在田间的主要栖息区域和产卵区域。经地学统计学分析发现,麦红吸浆虫在不同高度上分布的最佳拟合模型为球形-指数套合模型,属于聚集分布型,其主要分布区域为距地面53.278 3 cm以下。

Analysis of the trapping results of the wheat midge at different heights between wheat plants showed two activity peaks separately at 15cm and 45cm from the ground,which were the major habitat area and production region of wheat midge,respectively.Geo-statistics analysis showed that the best fitting model for wheat midge distribution at different heights was ball-index nested model,one of aggregation distribution models,and the activity range between wheat plants was under 53.2783cm.
