摘要
为了深入了解日本龟蜡蚧的发生和危害规律 ,对邢台市不同类型枣区日本龟蜡蚧的分布和危害情况进行了调查。结果表明 ,日本龟蜡蚧越冬雌成虫在枣树上的空间分布型为聚集型 ,个体群内和个体群间均为聚集分布 ;该害虫在寄主不同部位、不同方位的危害表现为 :外部 >内部 ,南方 >西方 >东方 >北方 ;不同的林分类型受害程度表现为 :生态环境单一的行栽婆枣林 >生态环境单一的散生慈枣林 >生态环境复杂的散生慈枣林。
In order to realize the occurrence and damage regularity of Ceroplastes japonicus ,its distribution and damage situation were investigated in different types of date tree stands in Xingtai. The results showed that the spatial distribution of the female adults, not only in the colony but also between the colonies,was of aggregation pattern on the tree.The damage regularity of the pest to the host trees was that exterior crown was damaged more seriously than interior one,and for different tree positions,damage degrees from high to light were ordered south, west, east and north parts of a crown, and in different stands the trees in simple ecological environment were damaged more seriously than the trees in complicated ecological environment.
