摘　　要：研究了云南紫胶虫(Kerria yunnanensis)在聚果榕、南岭黄檀、钝叶黄檀和偏叶榕上的发育、存活和繁殖情况.结果表明:在自然条件下,云南紫胶虫在钝叶黄檀上的种群初始密度最高,为181.17头.cm-2,聚果榕上最低,为145.27头.cm-2;雄虫占的比例以在南岭黄檀上最少,为0.19,偏叶榕和聚果榕上最多,为0.24;从幼虫到成虫的累积死亡率,南岭黄檀上最高,为90.03%,偏叶榕上最低,为87.05%;完成世代时间以在南岭黄檀上最长,为156d,聚果榕上最短,为140d;平均怀卵量以在南岭黄檀上最高,为536粒,聚果榕上最低,为345.86粒;虫体质量以在南岭黄檀上最大,为12.62mg,偏叶榕上最小,为9.03mg;世代净增值率以在南岭黄檀上最高,为48.51,聚果榕上最小,为32.79.综合比较4种不同寄主植物,南岭黄檀是云南紫胶虫夏季世代种群生长发育和繁殖最适宜的寄主.The study on the development, survivorship and reproduction of Kerria yunnanensis on 4 kinds of host trees indicated that in natural environment, the initial K. yunnanensis population density varied from 181.17 individuals on Dalbergia obtusifolia to 145.27 individuals on Ficusfacemosa per cm2, realized sex ratio varied from 0. 24 on D. obtusifolia and F. cunia to 0. 19 on D. balansae, accumulated population mortality from larval to adult varied from 90. 03% on D. balansae to 87.05% on F. cunia, and development period from larval to adult ranged from 156 days on D. balansae to 140 days on F. facemosa. The oviposition of K. yunnanensis varied from 536 eggs on D. balansae to 345.86 eggs on F. facemosa, female adult mass varied from 12.62 mg on D. balansae to 9.03 mg on F. cunia, and basic reproduction rate varied from 48.51 on D. balansae to 32.79 on F. facemosa. D. balansae was the most suitable host plant for K. chinensis summer life cycle.
