Chemical Ecology
LeBrun et al. (2015) found a behaviour, first noted and resulting from interactions between Solenopsis invicta and Nylanderia fulva, that detoxifies fire ant venom is expressed widely across ants in the subfamily Formicinae. This behavior was also studied and shown in experiments with B. patagonicus. See the biology section of the N. fulva page for a description of acidopore grooming and the use of formic acid for detoxification of a specific class of venoms that are produced by ants that may interact with formicines in the context of predation and food competition.
