白蜡虫寄生树良种选育研究

我国白蜡生产历史悠久,地域辽阔,云南、四川、湖南、西藏等20多个省区都有白蜡虫分布。但长期以来,广大产区仅用女贞树和白蜡树养虫、产蜡,寄主树种单一,成为影响我国白蜡生产发展的重要原因之一。吴次彬教授提出,为发展白蜡资源开展寄主树选育研究。1986年笔者分别从福建、四川、湖南、辽宁、云南等省的白蜡产区引入11个寄主树种,在云南景东育苗造林,放养白蜡虫,从中选出优良寄主树种华南小蜡、散生女贞。现将2树种研究结果总结如下。

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 I. 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.
