摘　　要：以白星花金龟为研究对象,采用比较法研究了不同生境对白星花金龟种群动态和雌雄比的影响。结果表明:不同生境对白星花金龟的种群数量影响较大,且种群增长率仅仅在5月/6月为正增长,此后的几个月均为负增长;除了葡萄地生境外,其余生境的种群数量在种群动态中均有2个高峰;白星花金龟雌雄比平均值为0.85∶1,雌雄比不仅受生境的影响,也受到种群数量的影响。Liocola brevitarsis Lewis was used as research object, the comparative method was adopted to study the influence of different habitats on population dynamics and female and male ratio of Liocola brevitarsis Lewis. The results showed that different habitats had large impact on the population number, and population growth rate was positive only in May/June,others were negative. The population dynamics all had two peaks except vineyard habitat; the average of female and male ratio of Liocola brevitarsis Lewis was 0. 85 ： 1. Female and male ratio was not only affected by habitat, but also by the population number.
