Ding, X.Y. 2003a Biology and control of Pseudaulacaspis pentagona on oil nane.. Entomological Knowledge 40(3): 264-265.

Notes: White peach scale, P. pentagona, is one of the major insect pests of oil nane tree [Prunus salicina]. It has four generations per year and overwinters as impregnated adult female on the branches of oil nane under the conditions of Gutian country, Fujian province, China. The female begins to lay eggs when the mean temperature is 17 deg C. The peak of the larval population for each generation occurs separately at the early and middle parts of April, July and September, and the last part of October. Generations begin to overlap starting at the second generation. The population of the first generation is higher than that of others. The control of P. pentagona by various methods, including winter clipping, pesticide application and natural enemy release, is presented.
