Inapparent infection of honey bee pupae by Kashmir and sacbrood bee viruses in Australia

Abstract

SUMMARY Inapparent infection of pupae of Apis mellifera by Kashmir bee virus (KBV) and sacbrood virus (SBV) was detected by two different methods, in three consecutive summers, from two widely separated locations in Australia. The prevalence of inapparent KBV infections varied from year to year, in contrast to the more consistent levels of inapparent SBV infection. The implications of inapparent infection for the epizootiology of the viruses in Australia are discussed.
