“…We also hypothesize that a sequential invasion of bee colonies as it was postulated by Elzen et al (2000), with males first and females following could be reflected by specialized glomeruli e.g. sexual dimorphic glomeruli as described for several other insect species.…”

“…Males of the related beetle Carpophilus obsoletus release an aggregation pheromone that attracts both sexes (Petroski et al, 1994) leading to the hypothesisthat a similar pheromone could guide A. tumida into host beehives that have been parasitized already (Elzen, 2000;Neumann and Elzen, 2004). However, a sequential arrival of male and female A. tumida could not be observed (Spiewok and Neumann, 2012).…”

“…Until recently it was suggested that male hive beetles enter a beehive before the females, leading to the speculation, that male A. tumida may distribute an aggregation pheromone attractive for both sexes (Elzen, 2000;Neumann and Elzen, 2004) …”

“…The small hive beetle (Aethina tumida) is native to sub-Saharan Africa where it is an occasional parasite and scavenger of African (Apis mellifera scutellata) and Cape (Apis mellifera capensis) honeybee colonies (Lundie 1940;Smith 1953;Roberts 1971;Elzen et al 2000). Growth in the international trade of honeybees and hive products over the last two decades has resulted in the spread of A. tumida into several countries where its establishment has resulted in significant economic impacts upon the apiculture industry (Elzen et al 1999;Gillespie et al 2003).…”

Demonstrating the potential of a novel spider venom-based biopesticide for target-specific control of the small hive beetle, a serious pest of the European honeybee

The parasitic small hive beetle (Aethina tumida) feeds on pollen, honey and brood of the European honey bee (Apis mellifera); establishment in North America and Australia has resulted in severe economic damage to the apiculture industry. We report potential for the "in-hive" use of a novel biopesticide that is toxic to this invasive beetle pest but harmless to honeybees. Constructs encoding the spider venom neurotoxin ω-hexatoxin-Hv1a (Hv1a) linked to the Nor C-terminus of snowdrop lectin (GNA) were used to produce recombinant Hv1a/GNA and GNA/Hv1a fusion proteins. Both were similarly toxic to beetles by injection (respective LD 50 s 1.5 and 0.9 nmoles/g larvae), whereas no effects on adult honeybee survival were observed at injection doses of > 200 nmoles/g insect. When fed to A. tumida larvae, GNA/Hv1a was significantly more effective than Hv1a/GNA (LC 50 s of 0.52 and 1.14 mg/ml diet, respectively), whereas both proteins were similarly toxic to adults. Results suggested that the reduced efficacy of Hv1a/GNA against larvae was attributable to differences in the susceptibility of the fusion proteins to cleavage by gut serine proteases. In laboratory assays, A. tumida larval survival was significantly reduced when brood, inoculated with eggs, was treated with GNA/Hv1a. Keywords Small hive beetle (Aethina tumida) • European honeybee (Apis mellifera) • Fusion proteins • ω-hexatoxin-Hv1a • Snowdrop lectin (Galanthus nivalis agglutinin) Key message • The small hive beetle is a serious invasive pest of the European honeybee and represents a serious threat to apiculture. • Current chemical control methods are limited due to their inherent toxicity towards honeybees. • Here we report the potential use of a recombinant fusion protein, containing a spider venom neuropeptide linked to a plant "carrier" lectin, as an "in-hive" treatment for the control of small hive beetle larvae and adults which has no toxicity towards bees.

“…It has become an invasive species (Neumann and Article published by EDP Sciences 420 M. Eyer et al Elzen, 2004;Neumann and Ellis, 2008) and a severe pest in some regions (USA: Elzen et al, 2000;Australia: Spiewok et al, 2007). Freeflying SHB adults invade host colonies over several kilometers, mate and reproduce within hives (Neumann and Elzen, 2004;Spiewok et al, 2008).…”

-The small hive beetle (SHB, Aethina tumida) is a parasite and scavenger of honeybee colonies. Here, we conducted laboratory experiments to investigate the potential of SHB as a vector of honeybee viruses. Using RT-PCR methods, Deformed Wing Virus (DWV) was detected in adult SHBs that: (1) were fed with dead workers with deformed wings, (2) were fed with DWV-positive brood, and (3) were associated with DWV-contaminated wax. SHB became significantly more often infected through feeding on virus infected workers, brood and the virus contaminated wax compared to pollen and the controls, where no infections were found. DWV was also detected in adult SHB after trophallaxis with infected workers. Further, among SHBs identified as DWV-positive, 40% of beetles carried negative stranded RNA of DWV, indicating virus replication. Our results suggest that SHB can be infected with honeybee viruses via food-borne transmission and have the potential of being a biological vector of honeybee viruses.Apis mellifera / Aethina tumida / biological vector / deformed wing virus / honeybees / small hive beetle
