Keeping a low profile: small hive beetle reproduction in African honeybee colonies

Abstract: Small hive beetles (SHBs) Aethina tumida are parasites of honeybee colonies native to sub‐Saharan Africa and have become an invasive species. SHB mass reproduction can destroy entire host colonies, although it is very rare in populations of African honeybee subspecies. However, there are no data available on SHB cryptic low‐level reproduction in African host colonies. In the present study, we dissected entire African honeybee (Apis mellifera adansonii) colonies in Benin. The data obtained show that nondestruct… Show more

“…When SHBs mass reproduce, with often thousands of larvae (Neumann & Elzen, ), they can kill even strong colonies of European honey bee subspecies within 10 days (Neumann, Hoffmann, Duncan, & Spooner‐Hart, ), often resulting in the full structural collapse of the entire nest (Hepburn & Radloff, ). This is very rare in the native range of SHB in Africa in colonies of the respective local honey bee subspecies (Lundie, ; Neumann, ; Schmolke, ), where SHBs probably mostly rely on non‐destructive low‐level reproduction (Ouessou Idrissou, Straub, & Neumann, ). The higher susceptibility of European honey bee subspecies is probably due to quantitative differences in a range of social immunity traits compared to the African ones (e.g.…”

“…Indeed, there is ample evidence suggesting a trade-off between fecundity and longevity, energy reserves and starvation resistance (Grandison, Piper, & Partridge, 2009;Holliday, 1989;Leroi, Kim, & Rose, 1994;Partridge, Piper, & Mair, 2005). Interestingly, it has been noted that SHB can exhibit two distinct types of reproduction in association with honey bee host colonies: cryptic low-level reproduction, with few larvae present that do not harm colonies (Ouessou Idrissou, Straub, & Neumann, 2018;Spiewok & Neumann, 2006), and overt mass reproduction, with thousands of larvae often resulting in the full structural collapse of the entire colony in a short time (Hepburn & Radloff, 1998;Neumann, Hoffmann, Duncan, & Spooner-Hart, 2010;Spiewok et al, 2008). In the native range in Africa, mass reproduction of SHBs in association with local honey bee colonies is extremely rare (Neumann, 2017); low-level reproduction alone seems to be sufficient to explain local SHB population size (Ouessou Idrissou et al, 2018).…”

In sharp contrast, mass reproduction is more common in the invasive range of SHBs in the USA (Elzen et al, 1999;Neumann et al, 2016;Spiewok et al, 2008).…”

“…Within its native range, SHB are usually considered to be a minor pest (Pirk & Yusuf, 2015) and display low levels of reproduction with only few larvae being present (Idrissou et al. , 2019). Destructive mass reproduction with thousands of larvae resulting in the full structural collapse of the entire host nest (Hepburn & Radloff, 1998) can occur in Africa, but it is rare (Neumann, 2017).…”
