摘要

本文通过建立随机数学模型，讨论了有害羊蝇的灭绝和种群的持久性。使用适当的李雅普诺夫函数，这些苍蝇的灭绝取决于产卵时间和世代之间的时间。产卵期必须足够短。另一种被称为丝光绿蝇(Lucilia sericata)的苍蝇也会在许多地区袭击绵羊。这两种苍蝇都是温血脊椎动物的体外寄生虫，尤其是家养的羊。尽管这两个物种不同，但这两种苍蝇有着相同的线粒体DNA序列。一个足够小的产卵延迟就会导致两个苍蝇种群的迅速灭绝。

DYNAMICS OF DELAYED NICHOLSON’S BLOWFLIES MODELS

The extinction and the persistence of the population of the harmful sheep blowfly (Lucilia cuprina) are discussed in this paper through a stochastic mathematical model. Using appropriate Lyapunov functionals, the extinction of these flies depends on the time to oviposition and the time between generations. The oviposition period must be sufficiently short. Another species of blowfly, called Lucilia sericata, also attacks sheep in many areas. Both blowflies are ectoparasites of warm-blooded vertebrates, particularly domestic sheep. These two blowflies are related to sharing the same mitochondrial DNA sequences, although the two species are distinct. A sufficiently small egg-laying delay then leads to the rapid extinction of both blowfly populations.

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
