| 在实验室条件下，采用编制特定年龄生命表的方法，获得东亚小花蝽Orius sauteri和西花蓟马Frankliniella occidentalis的重要种群生物学参数，进而分析评价东亚小花蝽对西花蓟马的控害能力。结果表明：东亚小花蝽的净生殖力（22.6）和内禀增长率（0.1345）均大于西花蓟马（20.2、0.1225）。此外，东亚小花蝽的世代历期（23.17 d）和种群倍增时间（5.15 d）均小于西花蓟马（24.54 d、5.65 d）。另外，东亚小花蝽的单雌平均产卵量（61.8粒）大于西花蓟马（35.4粒）。综合上述研究结果说明，东亚小花蝽的种群扩繁速度大于西花蓟马，且具有控制西花蓟马种群增长的巨大潜力。 |

| In order to do research on the capacity of biocontrol of Orius sauteri to Frankliniella occidentalis, the age-specific life table and got a series of importantly biological parameters was established The life tables′ parameters showed that net reproductive rates (Ro\)(22.6)and the intrinsic rate of increase (rm\)(0.1345)of Osauteri were more than those of Foccidentalis′ (20.2, 0.1225). The Generation period（23.17 d）and the doubling time (t)(5.15 d)of Osauteri which were shorter than those of Foccidentalis′（24.54 d, 5.65 d). In the aspect of oviposition per female, the ability of Osauteri was better than Foccidentalis′ By means of comparative analysis of all above parameters, results showed that the propagation speed of Osauteri was greater than Foccidentalis′, and Osauteri had the huge potential to control Foccidentalis |
