Abstract: According to the investigation recently made in the persimmon orchards in the suburbs of Shijiazhuang City,6 species of persimmon scales are found: Eriococcus kaki.Eupulrinaria citricola,Paraceroslegia japonica,Ceroplastes ceriferus,Drosicha cerpleata,Partheuolecanium persicae. Among them, E. kaki and E.citricala are dominant species,and the latter is newly recorded in China.Usually,it is very typical that the persimmons are attacked by one dominant species,mixing with another or other species. The persimmon phenology and the life cycle of the principal scales have been studied. It is clear that the appearance of the scale is related to the persimmon phenology. As for E. kaki,the best control period is between the persimmon fruit bearings and the fruit expansion(around June 10);for E.citricala,in the process of fruit expansion(around mid June);for P. japonica,after fruit expansion(in the last ten das of June);for D.cerpleata, in the time of persimmon sproutings(in the first ten days of March). For the control of the persimmon scales,the chemical prevention plays an important role,while the utilization of the natural enemy may as well help. By spraying monocrotothos or omethoate,the scale population decreased by over 94%,and if monocrotothos is simultaneously applied on the top of the tree,the mortality of the scales can reach 100%.
