摘　　要： 研究了在27℃条件下,南方小花蝽取食蚕豆蚜的发育和繁殖情况,并组建了实验种群生命表和繁殖特征生命表,计算了生命表的有关参数。结果表明,南方小花蝽取食蚕豆蚜时的未成熟期平均为21.02d,雌成虫平均寿命为7.55d,其平均产卵量为35.55粒,日产卵量为6.29粒,平均产卵期5.6d。南方小花蝽的种群趋势指数为7.17,净生殖率为6.57;内禀增长能力为0.074 9,周限增长率为1.077 4,种群加倍时间为9.257 6d。 The growth and reproduction of Orius silirnis fed with black bean aphid were studied at 27℃, and the age specific and fecundity specific life tables were established. The results showed that development period from egg to adult was 21.02d, fecundity was 35.55, daily ovisition per female per day was 6.29, and ovisition period was 5.6d. Index of population trend（I） was 7.17, net reproductive rate（R0 ）was 6.57,innate capacity of population increase（rm）was 0. 074 9, finite rate of increase（k）was 1. 077 4, and doubling time（t）was 9. 257 6.
