| 摘 要： | 苹果全爪螨是影响我国苹果生产的重要害虫之一.为明确其在苹果树冠上的时空格局,在2007年5-11月整个生长季节,采用不同方位、不同层面随机取样的方法调查害螨数量.应用聚集度指标法和Iwao回归测度法分析苹果全爪螨在苹果树上的分布型及其变化动态.结果表明:苹果全爪螨在苹果树冠整体范围内前期和中期符合负二项分布,呈聚集型,基本成分为个体群,且个体间相互吸引.聚集强度随种群密度的消长而波动,表现出高密度、低聚块及低密度、高聚块的规律,并且在树冠的不同方位和不同层面上存在一定差异:个体群的聚块性南部最高,西部最低;树冠中、下层高于上层,内层高于外层. |

| Abstract: | Panonychus ulmi Koch is one of the important pest insects of apple production in China.To clarify the spatiotemporal dynamics of P.ulmi on the apple tree crowns in an apple orchard of Liaoning,Northeast China,an investigation with random sampling was conducted on the pest mite number at each direction and each layer of the crowns in the whole growth season from May to November 2007.The spatial distribution pattern and time series dynamics of P.ulmi were analyzed by calculating the indices of aggregation and... |
