摘　　要：通过野外调查和室内测试,结果表明:橄榄星室木虱Pseudophacopteron canarium在橄榄Canarium album和乌榄C.nigrum上均能完成生长发育,且其种群数量都有不同程度的增长,其中橄榄的2个品系间的星室木虱种群趋势指数(I)差异不大,分别为24.4165和20.0738,而乌榄的明显比橄榄的低,仅为9.7575,即乌榄的木虱数量增速较慢。在供试的寄主植物品种中,乌榄叶片中单宁含量是橄榄的3倍以上,而蛋白质含量相对较低。Effects of host plants on natural population of P. canarium were studied. The results showed that P. canarium completed life history on Canarium album and C. nigrum. The population density of P. canarium increased on both host plants, and the population trend indices （I） of two cultivated varieties of Chinese olive （ C. album） and C. nigrum were 24. 4165, 20. 0738 and 9. 7575 respectively, but the population number of P. canarium increased slower on C. nigrum than that on C. album. The content of tannin in the leaves of C. nigrum was over 2 times higher than that of C. album, whereas its content of protein was less
