The Study of Tropical Climate (Jinghong,Yunnan) Influence White Wax Scale

Jinghong City of Yunnan Province belongs to tropical monsoon climate.In order to study the ecological adaptation of white wax insect scales and expand the white wax production,different host trees were chosen to be planted in Jinghong and white wax scales were bred on the tree in 1992～1996.The result showed that high temperature,dry and intense sunshine were unfavorable to the growth and development of white wax scales.Female white wax scales could be reproduced,sex ratio was normal,but the next generation brood insect was small,the quantity of ovum was few.Tropical region was not suitable for brood insect base.Male insect secrete wax normally.In good environment condition area,white wax base can be built.
