Acute bee paralysis virus (ABPV) is a positive-sense, single-stranded RNA virus of the family Dicistroviridae and the namesake of the ABPV–KBV–IAPV (AKI) complex of closely related honey bee viruses. First described in the 1960s, ABPV is widespread and typically persists as a covert, asymptomatic infection — but at elevated titre it is acutely lethal, causing rapid paralysis and death of adults and brood. Its transformation from a harmless commensal into a significant cause of colony mortality is tied directly to the mite Varroa destructor, which both disseminates ABPV between bees and activates its replication within them (Genersch 2010; de Miranda 2010). ABPV is among the most virulent bee viruses on direct injection, yet its overall impact is governed by the covert/overt balance that the mite controls. This document synthesises the findings by theme and catalogues the landmark studies.
ABPV is a member of the family Dicistroviridae and forms, together with Kashmir bee virus (KBV) and Israeli acute paralysis virus (IAPV), the closely related AKI complex (de Miranda 2010). These three viruses share genome organization, serological cross-reactivity and a characteristic biology: widespread prevalence in honey bee colonies, a predominantly sub-clinical etiology, and extreme virulence at elevated titres — whether induced artificially or reached naturally. Because the members are so similar and recombine, careful molecular diagnostics are needed to distinguish them (de Miranda 2010).
ABPV is one of the most acutely virulent honey bee viruses. At low titre it is a covert, asymptomatic infection; when injected or amplified to high titre it causes rapid paralysis and death of both adult bees and brood within days. This stark contrast between a near-harmless covert state and lethal overt disease is the defining feature of the AKI complex (de Miranda 2010). The key determinant of which state prevails is the route and level of infection — direct introduction into the haemocoel (as the mite provides) bypasses the gut barriers that normally keep the virus covert, allowing explosive, lethal replication.
ABPV's emergence as a colony-killer is bound to the spread of Varroa destructor. Before the mite, the AKI viruses were generally considered harmless; epidemiological surveys and laboratory experiments then linked their newly acquired virulence in Europe and the USA to Varroa acting as both a disseminator of the virus between and within colonies and an activator of viral multiplication in larvae and adults (Genersch 2010). Field surveys consistently find ABPV in Varroa mites — for example in 36% of mite samples in a large French survey — supporting the mite's role in transmission (Tentcheva 2004).
ABPV is common but variable. A large French survey found ABPV in 58% of apiaries in adult bees and 23% in pupae, with persistent infection despite the absence of clinical signs — implying environmental triggers activate replication (Tentcheva 2004). ABPV is part of the acute-paralysis clade identified in monitoring studies as a lethal pathogen for entire colonies (McMenamin 2015), and it is among the most widely distributed bee viruses alongside DWV, SBV and BQCV (Beaurepaire 2020). Its contribution to overwintering losses is real but generally secondary to DWV in Varroa-infested colonies (Dainat 2012).
ABPV uses the transmission routes typical of bee viruses. It is vectored by Varroa (Genersch 2010); transmitted orally via contaminated food, with picorna-like viruses of this group detected in pollen and shown to be infective (Singh 2010); and transmitted vertically — viruses of this group are passed from queens to offspring through eggs (Chen 2006). The interplay of covert vertical maintenance and overt, mite-amplified horizontal spread mirrors the pattern seen across the AKI complex and DWV.
Applied & Environmental Microbiology · 2004 · 285 citations
Objective. Large-scale PCR survey of six viruses across 36 French apiaries and their mites.
Findings:
ABPV found in 58% of apiaries (adult bees) and 23% (pupae).
ABPV detected in 36% of Varroa samples — supporting the mite's transmission role.
Infections persisted without clinical signs, implying environmental activation of replication.
J. Invertebrate Pathology · 2010 · 191 citations
Objective. Comprehensive review of the AKI dicistrovirus complex that ABPV anchors.
Findings:
ABPV, KBV and IAPV form a complex of closely related Dicistroviridae with widespread prevalence.
Predominantly sub-clinical etiology contrasts with extreme virulence at elevated titres (induced or natural).
Frequently implicated in colony losses, especially under Varroa destructor infestation.
Reviews origins, geographic/host/tissue distribution, pathology, transmission, genetics and diagnostics.
Applied & Environmental Microbiology · 2006 · 165 citations
Objective. Examined queen tissues and offspring for six viruses including ABPV.
Findings:
Viruses of this group were detected in queen feces and reproductive tissues.
Viruses present in queens appeared in their eggs, larvae and adult workers — vertical transmission.
Veterinary Research · 2010 · 164 citations
Objective. Reviewed how Varroa transformed previously harmless bee viruses including ABPV.
Findings:
Until the late 1980s ABPV and relatives were considered harmless.
Their newly acquired virulence in Europe/USA was linked to Varroa destructor.
Varroa acts as a disseminator of the AKI viruses and an activator of their multiplication in larvae and adults.
Control options (tolerant bees, RNAi, biosecurity) unlikely to help short-term.
PLoS ONE · 2010 · 283 citations
Objective. Surveyed viruses in bees, pollen and non-Apis pollinators.
Findings:
Picorna-like viruses detected in pollen pellets; virus-contaminated food was infective.
Supports pollen/food-borne transmission and presence in non-Apis pollinators relevant to ABPV.
Applied & Environmental Microbiology · 2012 · 219 citations
Objective. Linked pathogens to winter-bee longevity over a 6-month monitoring.
Findings:
ABPV load was positively correlated with vitellogenin expression but, unlike DWV, was not the primary driver of reduced winter-bee lifespan.
Positions ABPV as a secondary contributor relative to DWV in Varroa-infested colonies.
