囊状幼虫病的流行与发展

Prevalence and development of Sacbrood virus

蜜蜂是生态系统中重要的传粉者,70%主要作物依靠蜜蜂授粉。囊状幼虫病毒(SBV)是蜂群中的一种常见病毒,严重威胁蜂群健康,特别是幼虫化蛹遭到严重破坏。本文综述了近年间有关囊状幼虫病的研究报道,比较东方蜜蜂和西方蜜蜂幼虫感染囊状病毒后在分子水平上的变化及两者的不同之处。目前,囊状幼虫病的致病机制尚不清楚,且防治措施缺乏系统性,仅依靠某段基因序列设计引物进行病毒感染判断,尚需要进一步的研究以深入了解该病毒。

Honeybees are the most important pollinators in the ecosystem,and 70%of the main crops depend on bees’pollination.Sacbrood virus(SBV)is a common virus in honeybee colonies,which seriously threatens the host health,especially the pupation stage.This article summarizes the research reports on SBV in recent years,and compares the pathogenic differences between Apis mellifera and Apis cerana in the molecular level.At present,the pathogenic mechanism of SBV is not clear,its prevention and control are not systematic,and the virus detection relies merely on a part of gene sequence for the infection judgment.Further research is needed to understand the virus in depth.
