The Geographic Distribution of the White Wax Scale, Ericerus pela Chavannes, in China

The monograph of the geographic distribution of the white wax scale has not been reported before. In the years 1980 to 1988, investigation on the white wax scale has been conducted. The investigation indicated that the white wax scale's distribution is from 85°08' to 121°23'E and 18° to 42° N; with an elevation of 4.7m to 3000m in vertical distribution; from the warm temperate zone to north temperate zone and from north subtropical zone to the south subtropical zone. The adaptibility of the white wax scale to different climatic environments and ecological conditions was quite strong and its plasticity quite big. The distribution of its natural enemies is basically the same as that of the white wax scale.
