Venom profile of the European carpenter bee Xylocopa violacea: Evolutionary and applied considerations on its toxin components [PDF]

open access: yesToxicon: X, 2022
Modern venomics is increasing its focus on hymenopterans such as honeybees, bumblebees, parasitoid wasps, ants and true wasps. However solitary bees remain understudied in comparison and the few available venom studies focus on short melittin-like ...
