为了研究蜂房细胞的入侵率，将一群雅氏瓦螨（varroa jacobsoni Oudemans）引入蜜蜂群落（Apis mellifera Linnaeus）。对于每个实验，一个或两个其他类似的菌落被处理，并评估对入侵率的影响。结果表明，侵染率随蜂群数量的增加而增加，随蜂群数量的增加而减少。这在入侵率有限的情况下是可以预料到的，因为蜜蜂必须携带螨虫接近孵化细胞才能进行入侵，而且只有有限数量的蜜蜂可以同时接近孵化细胞。此外，当有幼巢存在时，入侵率降低。这一违反直觉的结果可能是因为螨虫更喜欢幼小的蜜蜂，幼小的蜜蜂很可能留在育雏巢区域，而育雏巢中的幼小蜜蜂被划分在适合入侵的育雏细胞区域和不适合螨虫入侵的育雏细胞区域。因此，增加尚不适合螨虫入侵的幼卵数量可能会降低入侵率。适合螨入侵的巢细胞存在的时间差异似乎不影响螨的入侵率。
To study the rate of invasion into brood cells, a group of varroa mites, Varroa jacobsoni Oudemans, was introduced into honeybee colonies, Apis mellifera Linnaeus. For each experiment one or two otherwise comparable colonies was treated, and the effect on the rate of invasion was assessed. The results showed that the rate of invasion increases with the number of available brood cells, and decreases with the size of the honeybee population. This is expected when the rate of invasion is limited because the bees have to carry the mites close to a brood cell for invasion to occur, and only a limited number of honeybees can come close enough to a brood cell simultaneously. In addition, the rate of invasion decreased when young brood was present. This counterintuitive result may arise because the mites prefer young honeybees, young honeybees are likely to stay in the brood nest area, and young honeybees in the brood nest are divided over areas with brood cells that are suitable for invasion and over areas with brood cells that are unsuitable for invasion by mites. Hence, an increase in the amount of young brood, which is not yet suitable for invasion by mites, may decrease the invasion rate. Differences in the period during which brood cells suitable for mite invasion were available to the mites, appeared not to affect the rate of invasion.
