Abstract: The Chinese white wax scale is an important economic and benificial insect in China. The male larva has the function of secreting a kind of white wax which is of great economic value. Though the female larva does not have this function, the female adult may produce the eggs which are the source of male lavas.The insect in question is distributed widely in China, mainly between 23—40 degrees N. latitude and from 50 to over 2,000 meters above sea level, A remarkable capacity of adapting itself to local ecological conditions has been shown by this insect. It may be asserted that there are no differences between the male and female insects in geological distribution and in their requirements for the climate and host plants.In the past the production of the wax and the raising of white wax scale "seeds" were not carried out in one and the same place only because people have different productive purposes. In some places they raised the "seeds" only for sale, while in others they did not raise the "seeds" but purchased them for producing the wax. In recent years this situation has gradually changed. People in many old white wax producing areas have increased the output of white wax by raising the "seeds" on their own. Consequently, good harvests of both wax and "seeds" have been obtained in these areas for several years running.
