论文摘要
蠕虫的生殖习惯对于研究其传播动力学很重要。对于由泊松或负二项式模型分发的寄生虫种群，已经研究了这些习惯。但是，还有其他描述这些人群的统计模型，例如零膨胀的模型，但没有分析生殖特征。使用寄生虫种群的任意模型，我们对每位宿主的女性和男性分布进行建模，从这些宿主分布，我们对不同的生殖变量进行了建模，例如肥沃的女性的平均数量，平均卵产量，交配概率，平均受精卵的产生。我们表明，这些变量由于负密度依赖性繁殖力的影响而变化，这是蠕虫寄生虫的特征。我们介绍了一些特定模型获得的结果。
The reproductive habits of helminths are important for the study of the dynamics of their transmission. For populations of parasites distributed by Poisson or negative binomial models, these habits have already been studied. However, there are other statistical models that describe these populations, such as zero-inflated models, but where reproductive characteristics were not analyzed. Using an arbitrary model for the parasite population, we model the distribution of females and males per host, and from these we model the different reproductive variables such as the mean number of fertile females, the mean egg production, the mating probability, the mean fertilized egg production. We show that these variables change due to the effects of a negative density-dependence fecundity, a characteristic of helminth parasites. We present the results obtained for some particular models.
