This paper reported on parthenogeneticto, morphological character, distribution host plant, damage and control of Kuwanaspis pseudoleucaspis (Kuwana) phyllo-stachys pubescens which is a major bamboo scale. This scale is found in Anhui, Jiangsu, and zhejiang provinces. It has two generations a year in Anhui and passes over winter in form of adult female. The female occures in early July and middle of September respectively. The peaks of laying and hatching eggs almost coincide. For the peak is in middle June and for the second, from early to middle August. Eeach female lays 7?4 eggs and hatching rate is 92% or 87.7% respectively for each generation, It passes winter in late November. The predominant natural enemies of the scale are parasitic Encyrtidae and pretory laby beetle Chilocorus kmvanae or Telsimia sp.With spray of 50% Malathion or 25% Imidan emulsion in 1000 times of water, the mortality rate of the scale would reach over 85%.
