On the Climatic Zones for Lac Insects along with Their Evaluation and Exploitation in Yunnan, China

Our survey in the lac-producing areas in Yunnan has demonstrated that these areas are characteristic of longitude-oriented distribution with remarkable vertical zonal variations. Based on the survey, they are divided into three regions and three zones of different altitudes. The three regions are western Wuliang mountain, Wuliang-Ailao mountains and eastern Ailao mountain. The altitudes of the three zones are 600~800 meters, 800~1 300 meters and 1 300~1 500 meters respectively. Our division exactly reflects the conditions in the lac-producing areas and is of great value for the understanding of the distribution of lac resources and the arrangement of lac production.
