摘　　要：为了解浙江省淳安县中华蜜蜂囊状幼虫病和欧洲幼虫腐臭病病原[中蜂囊状幼虫病毒(Chinese sacbrood virus,CSBV)和蜂房球菌(Melissococcus pluton)]全年流行情况,于2019年1月—12月采集淳安县5个饲养点的中蜂工蜂,并采用聚合酶链式反应检测方法,监测这2种病原在蜂群内的动态变化情况。结果显示:CSBV蜂群感染率在春季3月最高,为84%,到夏季7月降到最低,又从秋季开始升高,一直延续到冬季;蜂房球菌感染率从春季开始升高,到夏季开始下降,又从秋季开始升高,在10月和11月达到全年最高水平,为72%,冬季略有下降;在一年当中,蜂群内中蜂囊状幼虫病和欧洲幼虫腐臭病病原具有共同存在的现象;通过实时荧光定量聚合酶链式反应检测发现,秋季蜂房球菌存在的蜂群内CSBV载量显著高于单一检出CSBV的蜂群(P<0.05)。总之,本研究明确了浙江省淳安县中蜂2种主要病原在蜂群中的全年流行动态情况,可为该地区中蜂病害的预防和控制提供理论指导。In order to understand the annual epidemic situation of Chinese sacbrood disease and European foulbrood disease pathogens[Chinese sacbrood virus(CSBV)and Melissococcus pluton,respectively]in Chinese honeybee(Apis cerana cerana)of Chun’an County of Zhejiang Province,the workers in Chinese honeybee colonies were collected from five breeding sites in Chun’an County from January to December in 2019,and the dynamic changes of the two main disease pathogens in the Chinese honeybee colonies were monitored by polymerase chain reaction(PCR).The results showed that the colony infection rate of CSBV was the highest in March of spring(84%),and it decreased to the lowest in July of summer,then increased from autumn to winter.The infection rate of M.pluton increased from spring to summer,and then increased from autumn to the highest level of 72%in late autumn(October)and early winter(November),and decreased slightly in winter.Furthermore,there was co-infection phenomenon of these two disease pathogens in honeybee colonies in the whole year.The results of real-time quantitative PCR showed that the viral load of CSBV in colonies with M.pluton in autumn was significantly higher than that in the colonies with a single infected CSBV(P<0.05).In conclusion,the annual epidemic dynamics of two main disease pathogens of Chinese honeybee is clarified in Chun’an County of Zhejiang Province,which can provide theoretical guidances for the prevention and control of Chinese honeybee diseases in this region.
