STUDIES ON THE SCALE INSECTS ATTACTING GREEN HOUSE PLANTS IN NORTH CHINA

There are 51 species of scale insects,most of them are the species of Diaspidae, Pseudococcidae and Coccidae,attactting greenhouse plants in north China.The perennial,woody or evergreen plants are damaged by the scale insects more seriously than the others.In the green house plant,the permanently ornamental plants and those poorly managed are easy to be damaged by the scale insects.The polyphagous or polyvoltine scale insects can attact the plants seriously, and they often have the characters of the generation overlapping,high population density and fast spreading.In this paper,the management countermeasuresfor the greenhouse scale insects are given.
