“…Therefore, within the predicted current and future range expansion of SHB presented here, honey bee colonies will inevitably be present and thus potentially exposed to this pest species. Moreover, SHBs infest colonies of other social bees as well (Cervancia et al, ; Greco et al, ; Spiewok & Neumann, ) and may also use solitary bees as hosts (Gonthier et al, ). Even though the impact and its magnitude are unknown for many social bees, the predicted invasion risk could have a broad impact on this important group of pollinators and the ecosystem service they provide.…”

“…However, knowledge of the potential effects of climate change on such species is currently lacking (Le Conte & Navajas, 2008). The small hive beetle (SHB, Aethina tumida, Murray) is a long known parasite of social bee colonies (honey bees: A. mellifera (Lundie, 1940); Apis cerana (Cervancia, Guzman, Polintan, Dupo, & Locsin, 2016), bumblebees: Bombus impatiens (Spiewok & Neumann, 2006), stingless bees: (Greco et al, 2010) native to sub-Saharan Africa, which can also infest nests of solitary bees (Megachile rotundata, Gonthier et al, 2019). Since 1996, SHB has become an invasive species and has established local populations on every continent except Antarctica (Neumann et al, 2016;Schäfer et al, 2019).…”

Climate change and biological invasions are two major global environmental challenges. Both may interact, e.g. via altered impact and distribution of invasive alien species. Even though invasive species play a key role for compromising the health of honey bees, the impact of climate change on the severity of such species is still unknown. The small hive beetle (SHB, Aethina tumida, Murray) is a parasite of honey bee colonies. It is endemic to sub‐Saharan Africa and has established populations on all continents except Antarctica. Since SHBs pupate in soil, pupation performance is governed foremost by two abiotic factors, soil temperature and moisture, which will be affected by climate change. Here, we investigated SHB invasion risk globally under current and future climate scenarios. We modelled survival and development time during pupation (=pupal performance) in response to soil temperature and soil moisture using published and novel experimental data. Presence data on SHB distribution were used for model validation. We then linked the model with global soil data in order to classify areas (resolution: 10 arcmin; i.e. 18.6 km at the equator) as unsuitable, marginal and suitable for SHB pupation performance. Under the current climate, the results show that many areas globally yet uninvaded are actually suitable, suggesting considerable SHB invasion risk. Future scenarios of global warming project a vehement increase in climatic suitability for SHB and corresponding potential for invasion, especially in the temperate regions of the Northern hemisphere, thereby creating demand for enhanced and adapted mitigation and management. Our analysis shows, for the first time, effects of global warming on a honey bee pest and will help areas at risk to prepare adequately. In conclusion, this is a clear case for global warming promoting biological invasion of a pest species with severe potential to harm important pollinator species globally.

“…The geographic expansion of the invasive SHB to temperate climatic zones means that it can now also encounter various bumble bee species, whose colonies it is able to invade (Hoffmann et al, 2008). Not least, it has been recently shown that SHBs can also complete an entire life cycle in association with nests of solitary bees Megachile rotundata (Gonthier et al, 2019). Since SHB is a replicative host or biological vector for DWV (Eyer et al, 2009), such invasion may result in the transmission of viruses among bee species.…”

Numerous studies have recently reported on the discovery of bee viruses in different arthropod species and their possible transmission routes, vastly increasing our understanding of these viruses and their distribution. Here, we review the current literature on the recent advances in understanding the transmission of viruses, both on the presence of bee viruses in Apis and non-Apis bee species and on the discovery of previously unknown bee viruses. The natural transmission of bee viruses will be discussed among different bee species and other insects. Finally, the research potential of in vivo (host organisms) and in vitro (cell lines) serial passages of bee viruses is discussed, from the perspective of the host-virus landscape changes and potential transmission routes for emerging bee virus infections.

“…Previous studies mainly focused on survival of laboratory-reared adult SHB maintained with water as negative controls (Schmolke, 1974 (RSA); Ellis, Neumann, et al, 2002 TA B L E 1 Mortality of laboratoryreared and field-collected adult small hive beetles, Aethina tumida, under starvation from the endemic range in Africa and from the invasive range in North America up to 14 days (Ellis, Neumann, et al, 2002), 19 days (Schmolke, 1974), 19 days (Gonthier et al, 2019), and 26 days (Buchholz et al, 2008); this overall corresponds with the results reported here. However, these previous studies used varying methods and did neither compare freshly emerged laboratory-reared versus field-caught adults, males versus females nor endemic versus invasive ranges of SHB.…”

“…Small hive beetle (SHB), Aethina tumida, is an invasive species originating from sub-Saharan Africa (Lundie, 1940) that has spread almost globally (Neumann, Pettis, & Schäfer, 2016;Ouessou Idrissou, Huang, Yañez, & Neumann, 2019). The SHB lives in association with honey bee colonies, but can also infest colonies of other social bees as well as solitary bee nests (Gonthier et al, 2019;Neumann et al, 2016). Inside host nests, SHB adults can feed themselves on honey, pollen, host brood, dead or live adult bees or tricking honey bee workers into trophallactic feeding, mate and reproduce (Neumann et al, 2016).…”

Evolution of starvation resistance in an invasive insect species, Aethina tumida (Coleoptera: Nitidulidae)

Starvation resistance, or the ability to survive periods without food, can shed light on selection pressure imposed by food scarcity, including chances to invade new regions as a result of human transport. Surprisingly, little information is known about starvation resistance for invasive insect species. Given that native and invasive populations differ in starvation resistance, this would suggest different selection scenarios and adaptive shifts fostering invasion success. Here, we show striking differences in starvation resistance of adult small hive beetles Aethina tumida (SHB) between native and invasive populations. In the laboratory, starvation resistance of freshly emerged laboratory‐reared and field‐collected adult females and males was evaluated in the beetle's native African range and in their invasive North American range. SHB in their native African range survived longer than SHB in their invasive North American range. Across ranges, females survived longer than males. Field‐collected SHB survived in Africa longer than freshly emerged ones, but not in the invasive range. This suggests no selection for starvation resistance in the invasive range, possibly due to differences between African and European‐derived honey bee hosts facilitating a trade‐off scenario between reproduction and starvation resistance. The ability of adult females to survive up to two months without food appears to be one factor contributing to the invasion success of this species. Assuming food availability is usually high in the invasive ranges, and trade‐offs between starvation resistance and fecundity/reproduction are common, it seems as if selection for starvation resistance during transport could set up potential trade‐offs that enhance reproduction after invasion. It would be interesting to see if this is a possible general pattern for invasive insect species.
