A Study on Selection of Host Plant of the White Wax Scale

From 1986 to 1990, experiments on selection of favourable host plants of the white wax scale were carried out in Jingdong County, Yunnan Province. The results show that the two fast-growing and drought-resistant species with wide adaptability, Ligustrum calleryanum Decene and L. confusm Decene, are preferred host plants which can produce quality wax and brood-insects. So we recommend these two species be applied to large-scale wax production.
