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.
