- 摘要:
- 以重阳木为试材，调查了重阳木（Bischofia polycarpa）叶片上佛州龟蜡蚧（Ceroplastes floridensis）的空间分布格局。结果表明：多数叶片上佛州龟蜡蚧的个体数不多，每叶虫数与叶片数呈明显幂函数递减关系；该蜡蚧主要分布在重阳木正面叶脉，背面叶脉次之，叶脉间最少；在叶片正面主脉两侧的叶脉上其密度接近正态分布，叶片中部叶脉的蜡蚧密度显著高于叶片基部和叶片端部。根据佛州龟蜡蚧在重阳木叶脉上的分布规律，提出了一些佛州龟蜡蚧的防治建议。
- Abstract:
- Taking Bischofia polycarpa as material,the spatial distribution of Ceroplastes floridensis Comstock on Bischofia polycarpa leaves was investigated.The results showed that the scale insect had low numbers of individuals on most leaves,and the relationship between insect number per leaf and leaf number obviously decreased as a power law;they mostly distributed on leaf veins of leaf upper surface,next on leaf veins of leaf lower surface,and the least between the leaf veins;scale insect density on lateral veins at each side of main vein on leaf upper surface showed nearly normal distribution patterns,i.e.,insect density on leaf-middle lateral veins were significantly higher than those on leaf-base lateral veins and leaf-apex lateral veins.Based on the above distribution patterns of Ceroplastes floridensis,some corresponding control strategies were put forward.
