摘要: 广西开展紫胶虫引种试放已有30年.对紫胶虫的繁殖和生产,积累了一定的经验.为进一步查明本区发展紫胶生产的经济价值,我们对广西在冬代低温条件越冬保种地区的情况,作了系统的调查研究.现对广西紫胶产区的布局和有关越冬保种问题进行探讨.

Abstract: The regions for overwintering of seed lac of winter generation in Guangxi have been investigated;the experiences of introducing and breeding of lac insects(lraccifer laoca Kerr)for more than 30 years in the regions have been summarized.the author suggests that the rational layout of Iac production should be accorded with blonomics and ecocllmatological environments of 1ac insects;the areas of land for the row material product of lac insects and the bases for overwintering of seed Iac should be established;the overwlnterlng seed lac should be bred on different host plants to raise the propagatlve proportion of winter generation of the lac Insects;for raising the breeding technics.much of the work should be done.such as the management of host plants for overwlntering of lac insects.the prevention and control of the pests of lac insects and host plants.the cold resistant varieties of lac Insects adapted to local climate should be bred.in order to resolve the overwlntering of seed lac.Base on the Investigation of 55 counties in Guangxi,the author considers that 7 counties among them can be served as the first-class regions for overwlntering of seed late 13 as the sand-class;and 35 as the areas of land for raw material product of lac Insects of summer generation.
