我们提出了一个由寄生瓦螨（瓦螨破坏者）携带的急性麻痹病毒感染蜂群的简单数学模型。这是一个非线性常微分方程组的因变量：携带病毒的螨的数量，健康蜜蜂的数量和患病蜜蜂的数量。我们用分析和计算技术的混合来研究这个模型。我们的研究结果表明，根据模型参数和初始数据，存在病毒的蜂群在衰退和迅速消失之前，可以在多年内看起来像健康的蜂群一样运作（例如蜂群崩溃病，越冬损失）。这是一个事实的结果，在一个群体中需要一定数量的工蜂来维持和照顾窝，以确保继续生产新的蜜蜂。
We present a simple mathematical model of the infestation of a honeybee colony by the Acute Paralysis Virus, which is carried by parasitic varroa mites (Varroa destructor). This is a system of nonlinear ordinary dif- ferential equations for the dependent variables: number of mites that carry the virus, number of healthy bees and number of sick bees. We study this model with a mix of analytical and computational techniques. Our results indicate that, depending on model parameters and initial data, bee colonies in which the virus is present can, over years, function seemingly like healthy colonies before they decline and disappear rapidly (e.g. Colony Collapse Disor- der, wintering losses). This is a consequence of the fact that a certain number of worker bees is required in a colony to maintain and care for the brood, in order to ensure continued production of new bees.
