  • Antioxidant supplementation can reduce the survival costs of amino acid intake in honeybees 
    Archer, C. Ruth; Kohler, Angela; Pirk, Christian Walter Werner; Oosthuizen, Vinette; Apostolides, Zeno; Nicolson, Sue W. (University of Pretoria, 2014)
    Over-consuming amino acids is associated with reduced survival in many species, including honeybees. The mechanisms responsible for this are unclear but one possibility is that excessive intake of amino acids increases ...
  • Nutrition affects stress resistance in African honeybees (Apis mellifera scutellata) 
    Archer, C. Ruth; Pirk, Christian Walter Werner; Nicolson, Sue W.; Wright, Geraldine A. (Pretoria: University of Pretoria. Faculty of Natural and Agricultural Sciences. Department of Zoology & Entomology, 2014)
    1. Nutrition plays an important role in physiological stress resistance and by adjusting their intake of key nutrients, such as protein and carbohydrate, many animals can better resist stress. 2. Poor nutrition may ...
  • Resistance of developing honeybee larvae during chronic exposure to dietary nicotine 
    Human, Hannelie; Archer, C. Ruth; Du Rand, Esther Elizabeth; Pirk, Christian Walter Werner; Nicolson, Sue W. (Pretoria : University of Pretoria. Faculty of Natural and Agricultural Sciences. Department of Zoology & Entomology, 2014)
    The effects of pesticides on honeybee larvae are less understood than for adult bees, even though larvae are chronically exposed to pesticide residues that accumulate in comb and food stores in the hive. We investigated ...
