Varroa destructor reproductive success is considered an important character for determining the resistance of honey bees to this mite parasite. However, most of the published data are not comparable due to the different methods of ascertaining and reporting reproduction. A recently published technique that involves reconstructing mite families in older worker brood gives repeatable and reliable parameters. This methodology was used to compare various categories of reproduction of approximately 1,000 V. destructor females in each of three studies on Africanized bees in Brazil and Mexico and European bees in England. The most objective and useful measure was the determination of the number of viable females per female that had invaded the worker brood in singly infested cells, which was denominated the "effective reproduction rate". Viable females are those that can reach the adult stage and have a mate available. The effective reproduction rate in worker brood was 0.64, 0.73 and 1.01 in Brazil, Mexico and England, respectively. Standardization of reproduction determination techniques would make published data comparable and much more useful.
瓦螨的繁殖成功率被认为是确定蜜蜂对这种螨虫寄生虫抗性的一个重要特征。然而，由于确定和报告繁殖情况的方法不同，大多数已发表的数据无法进行比较。最近发表的一项技术，即重建老龄工蜂幼虫中的螨类家族，给出了可重复且可靠的参数。在巴西和墨西哥对非洲化蜜蜂以及在英国对欧洲蜜蜂进行的三项研究中，均使用该方法比较了约1000只瓦螨雌螨的各类繁殖情况。最客观且有用的衡量标准是确定在单个受侵染巢房中侵入工蜂幼虫的每只雌螨产生的存活雌螨数量，这被称为“有效繁殖率”。存活雌螨是指那些能够发育到成虫阶段且有交配机会的雌螨。在巴西、墨西哥和英国，工蜂幼虫中的有效繁殖率分别为0.64、0.73和1.01。繁殖测定技术的标准化将使已发表的数据具有可比性且更有用。
