【摘要】：以白星花金龜為研究對象,采用比較法研究了不同生境對白星花金龜種群動(dòng)態(tài)和雌雄比的影響。結(jié)果表明:不同生境對白星花金龜?shù)姆N群數(shù)量影響較大,且種群增長率僅僅在5月/6月為正增長,此后的幾個(gè)月均為負(fù)增長;除了葡萄地生境外,其余生境的種群數(shù)量在種群動(dòng)態(tài)中均有2個(gè)高峰;白星花金龜雌雄比平均值為0.85∶1,雌雄比不僅受生境的影響,也受到種群數(shù)量的影響。
[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.
