【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。
[Abstract]:In order to brevitarsis as the research object, using the method of comparison of effect of different habitats on Star beetle population dynamics and sex ratio. The results showed that the population in different habitats of white star beetles affected the population growth rate, and only in May /6 months of positive growth, a few months after this are negative growth; in addition to overseas students grape populations, the rest habitat has 2 peaks in population dynamics; brevitarsis sex ratio of the average value is 0.85 to 1, the ratio of male to female is not only influenced by habitat, are also affected by the population.
