Abstract: Host plants provide lac insects with food and habitats,therefore constituting the material base of lac production.Approximately 300 species of lac hosts have been found in China through our years'researches and investigations, among which 13 favourable species have been sorted out.These 13 species are of wide adaptablity and can produce more and higher-quality lac than others.Quite a few achievements have been obtained in our study of physiology,ecology,biology,breeding and lac plantation establishing techniques of these excellent plants.What we have done has greatly promoted lac production and helped to realize intensive management in lac production and to secure high and stable lac yield.
