  • Adult diet does not compensate for impact of a poor larval diet on stress resistance in a tephritid fruit fly 
    Weldon, Christopher William; Mnguni, Sandiso; Demares, Fabien J.; Du Rand, Esther Elizabeth; Malod, Kevin; Manrakhan, Aruna; Nicolson, Sue W. (Company of Biologists, 2019-03)
    Adult holometabolous insects may derive metabolic resources from either larval or adult feeding, but little is known of whether adult diets can compensate for deficiencies in the larval diet in terms of stress resistance. ...
  • Honeybee health in Africa - a review 
    Pirk, Christian Walter Werner; Strauss, Ursula; Yusuf, Abdullahi Ahmed; Demares, Fabien J.; Human, Hannelie (Springer, 2016-05)
    Honeybee (Apis mellifera L.) pathogens and parasites and the negative effects thereof on honeybee populations remain an issue of public concern and the subject of active research. Africa with its high genetic diversity ...
  • Neonicotinoids decrease sucrose responsiveness of honey bees at first contact 
    Démares, Fabien J.; Demares, Fabien J.; Pirk, Christian Walter Werner; Nicolson, Sue W.; Human, Hannelie (Elsevier, 2018-07)
    For two decades, neonicotinoid insecticides have been extensively used worldwide. Targeting neuronal receptors, they have deleterious effects on the behaviour and physiology of many insects. Bees are exposed to these ...
  • Sucrose sensitivity of honey bees Is differently affected by dietary protein and a neonicotinoid pesticide 
    Demares, Fabien J.; Crous, Kendall L.; Pirk, Christian Walter Werner; Nicolson, Sue W.; Human, Hannelie (Public Library of Science, 2016-06-07)
    Over a decade, declines in honey bee colonies have raised worldwide concerns. Several potentially contributing factors have been investigated, e.g. parasites, diseases, and pesticides. Neonicotinoid pesticides have ...
