Fire Ant Venom Alkaloids Inhibit Biofilm Formation [PDF]
Toxins, 2019 Biofilm formation on exposed surfaces is a serious issue for the food industry and medical health facilities. There are many proposed strategies to delay, reduce, or even eliminate biofilm formation on surfaces. The present study focuses on the applicability of fire ant venom alkaloids (aka ‘solenopsins’, from Solenopsis invicta) tested on polystyrene ...

Intra-colony venom diversity contributes to maintaining eusociality in a cooperatively breeding ant
BMC Biology, 2023 Background Eusociality is widely considered to evolve through kin selection, where the reproductive success of an individual’s close relative is favored at the expense of its own. High genetic relatedness is thus considered a prerequisite for eusociality.
