  • Effects, but no interactions, of ubiquitous pesticide and parasite stressors on honey bee (Apis mellifera) lifespan and behaviour in a colony environment 
    Retschnig, Gina; Williams, Geoffrey R.; Odemer, Richard; Boltin, Janina; Di Poto, Cornelia; Mehmann, Marion M.; Retschnig, Peter; Winiger, Pius; Rosenkranz, Peter; Neumann, Peter (Wiley, 2015-11)
    Interactions between pesticides and parasites are believed to be responsible for increased mortality of honey bee (Apis mellifera) colonies in the northern hemisphere. Previous efforts have employed experimental approaches ...
  • First detection of viruses in Africanized honey bees from Peru 
    Yanez, Orlando; Tejada, G.; Neumann, Peter (Springer, 2014)
    No abstract available.
  • Genotypic diversity in queenless honey bee colonies reduces fitness 
    Bratkowski, Janusz; Pirk, Christian Walter Werner; Neumann, Peter; Wilde, Jerzy (International Bee Research Association, 2012)
    Honey bee queens mate with many males. The resulting genotypic diversity appears to enhance fitness of queenright colonies (those colonies with a reproductive queen present) which is difficult to measure, because measures ...
  • Go East for better honey bee health : Apis cerana is faster at hygienic behavior than A. mellifera 
    Lin, Zheguang; Page, Paul; Li, Li; Qin, Yao; Zhang, Yingying; Hu, Fuliang; Neumann, Peter; Zheng, Huoqing; Dietemann, Vincent (Public Library of Science, 2016-09-08)
    The poor health status of the Western honey bee, Apis mellifera, compared to its Eastern counterpart, Apis cerana, is remarkable. This has been attributed to lower pathogen prevalence in A. cerana colonies and to their ...
  • Hit-and-run trophallaxis of small hive beetles 
    Neumann, Peter; Naef, Jan; Crailsheim, Karl; Crewe, Robin M.; Pirk, Christian Walter Werner (Wiley, 2015-12)
    Some parasites of social insects are able to exploit the exchange of food between nestmates via trophallaxis, because they are chemically disguised as nestmates. However, a few parasites succeed in trophallactic solicitation ...
  • Increased response to sequential infections of honeybee, Apis mellifera scutellata, colonies by socially parasitic Cape honeybee, A. m. capensis, workers 
    Neumann, Peter; Pirk, Christian Walter Werner (Nature Publishing Group, 2019-05-20)
    Cape honeybee, Apis mellifera capensis, workers can be social parasites and host colonies can defend themselves by rejection of such workers. Using the pseudo-clonal obligate parasitic lineage of A. m. capensis and ...
  • Neonicotinoid insecticides can serve as inadvertent insect contraceptives 
    Straub, Lars; Villamar-Bouza, Laura; Bruckner, Selina; Chantawannakul, Panuwan; Gauthier, Laurent; Khongphinitbunjong, Kitiphong; Retschnig, Gina; Troxler, Aline; Vidondo, Beatriz; Neumann, Peter; Williams, Geoffrey R. (The Royal Society, 2016-05-06)
    There is clear evidence for sublethal effects of neonicotinoid insecticides on non-target ecosystem service-providing insects. However, their possible impact on male insect reproduction is currently unknown, despite the ...
  • Neonicotinoid pesticides severely affect honey bee queens 
    Williams, Geoffrey R.; Troxler, Aline; Retsching, Gina; Roth, Kaspar; Yanez, Orlando; Shutler, Dave; Neumann, Peter; Gauthier, Laurent (Nature Publishing Group, 2015-10-13)
    Queen health is crucial to colony survival of social bees. Recently, queen failure has been proposed to be a major driver of managed honey bee colony losses, yet few data exist concerning effects of environmental stressors ...
  • No spatial patterns for early nectar storage in honey bee colonies 
    Eyer, Michael; Greco, Mark K.; Lang, Johann; Neumann, Peter; Dietemann, Vincent (Springer, 2016-02)
    Honey bees, Apis, forage for nectar and pollen, which are subsequently stored in cells of their nests. Despite the importance of honey storage for colony survival, very little is known about decision making by honey bee ...
  • Potential for virus transfer between the honey bees Apis mellifera and A. cerana 
    Yanez, Orlando; Zheng, Huo-Qing; Su, Xiao-Ling; Hu, Fu-Liang; Neumann, Peter; Dietemann, Vincent (Taylor and Francis, 2015)
    Viruses seem to play a key role in European honey bee, Apis mellifera health, and have a much broader host spectrum than previously thought. Few studies have investigated interspecific virus transfer within the genus Apis. ...
  • Quo vadis Aethina tumida? Biology and control of small hive beetles 
    Neumann, Peter; Pettis, Jeff S.; Schazfer, Mark O. (SpringerOpen Journal, 2016-05)
    Small hive beetles (SHBs) are generalists native to sub-Saharan Africa and reproduce in association with honeybees, bumblebees, stingless bees, fruits and meat. The SHB has recently become an invasive species, and introductions ...
  • Reproductive biology of the Cape honeybee : a critique of Beekman et al. 
    Pirk, Christian Walter Werner; Lattorff, H. Michael G.; Moritz, Robin F.A.; Sole, Catherine L.; Radloff, Sarah E.; Neumann, Peter; Hepburn, H. Randall; Crewe, Robin M. (Oxford University Press, 2012-07)
    A critique of “Asexually Produced Cape Honeybee Queens (Apis mellifera capensis) Reproduce Sexually”: Laying workers of the Cape honeybee parthenogenetically produce female offspring whereas queens typically produce males. ...
  • A scientific note on Israeli acute paralysis virus infection of Eastern honeybee Apis cerana and vespine predator Vespa velutina 
    Yanez, Orlando; Zheng, Huo-Qing; Hu, Fu-Liang; Neumann, Peter; Dietemann, Vincent (Springer, 2012-09)
    The Israeli acute paralysis virus (IAPV, Maori et al., 2007; de Miranda et al., 2010) is widespread in Western honey bees (Apis mellifera) for whom it can be a marker of colony losses (Cox-Foster et al., 2007). It has ...
  • Sex-specific differences in pathogen susceptibility in honey bees (Apis mellifera) 
    Retschnig, Gina; Williams, Geoffrey R.; Mehmann, Marion M.; Yanez, Orlando; De Miranda, Joachim R.; Neumann, Peter (Public Library of Science, 2014-01-17)
    Sex-related differences in susceptibility to pathogens are a common phenomenon in animals. In the eusocial Hymenoptera the two female castes, workers and queens, are diploid and males are haploid. The haploid susceptibility ...
  • Short-sighted evolution of virulence in parasitic honeybee workers (Apis mellifera capensis Esch.) 
    Moritz, Robin F.A.; Pirk, Christian Walter Werner; Hepburn, H. Randall; Neumann, Peter (Springer, 2008)
    The short-sighted selection hypothesis for parasite virulence predicts that winners of within-host competition are poorer at transmission to new hosts. Social parasitism by self-replicating, female-producing workers occurs ...
  • Small hive beetles are facultative predators of adult honey bees 
    Pirk, Christian Walter Werner; Neumann, Peter (Springer, 2013-11)
    Foraging animals can choose to act as predators or not depending on the level of defensiveness of the potential prey. This requires prior evaluation of prey defensiveness, which can be variable, e.g. young insects are ...
  • Social apoptosis in honey bee superorganisms 
    Page, Paul; Lin, Zheguang; Buawangpong, Ninat; Zheng, Huoqing; Hu, Fuliang; Neumann, Peter; Chantawannakul, Panuwan; Dietemann, Vincent (Nature Publishing Group, 2016-06-06)
    Eusocial insect colonies form superorganisms, in which nestmates cooperate and use social immunity to combat parasites. However, social immunity may fail in case of emerging diseases. This is the case for the ectoparasitic ...
  • Varroa destructor : research avenues towards sustainable control 
    Dietemann, Vincent; Pflugfelder, Jochen; Anderson, Denis; Charriere, Jean-Daniel; Chejanovsky, Nor; Dainat, Benjamin; De Miranda, Joachim R.; Delaplane, Keith; Dillier, Franz-Xaver; Fuch, Stefan; Gallmann, Peter; Gauthier, Laurent; Imdorf, Anton; Koeniger, Nikolaus; Kralj, Jasna; Meikle, William; Pettis, Jeff; Rosenkranz, Peter; Sammataro, Diana; Smith, Deborah; Yanez, Orlando; Neumann, Peter (International Bee Research Association, 2012)
    Pollination by honey bees plays a key role in the functioning of ecosystems and optimisation of agricultural yields. Severe honey bee colony losses worldwide have raised concerns about the sustainability of these pollination ...
