有几个因素威胁着蜜蜂的健康，其中寄生螨狄斯瓦螨和畸形翅病毒起着主要作用。最近，螨和病毒之间的危险的相互作用进行了详细的研究和过渡，引发螨喂养，从一个良性的隐性感染到一个毁灭性的病毒爆发，其特征是一个激烈的病毒复制，与一些特征性的症状，被描述。为了深入了解这一关键转变之前的事件，我们进行了标准化实验室实验，旨在研究寄生在无症状蜜蜂中的影响，以建立此类影响与蜜蜂死亡率之间的关系。看来，寄生改变了蜜蜂调节水交换的能力，这反过来，有严重的影响蜜蜂survival.These结果进行了讨论，旨在减轻寄生虫对蜜蜂健康的影响可能的新策略。(C)2012爱思唯尔有限公司保留所有权利。
Several factors threaten the health of honeybees; among them the parasitic mite Varroa destructor and the Deformed Wing Virus play a major role. Recently, the dangerous interplay between the mite and the virus was studied in detail and the transition, triggered by mite feeding, from a benign covert infection to a devastating viral outbreak, characterized by an intense viral replication, associated with some characteristic symptoms, was described. In order to gain insight into the events preceding that crucial transition we carried out standardized lab experiments aiming at studying the effects of parasitization in asymptomatic bees to establish a relationship between such effects and bee mortality. It appears that parasitization alters the capacity of the honeybee to regulate water exchange; this, in turn, has severe effects on bee survival.These results are discussed in light of possible novel strategies aiming at mitigating the impact of the parasite on honeybee health.
