  abstract = {{G}roup hunting, nomadism, wingless queens and colony fission characterize army ants, allowing them to have become the main tropical arthropod predators, mostly of other social insects. {W}e studied the reactions of different ant species to the {N}ew {W}orld army ants {E}citon burchellii ({WESTWOOD}, 1842) and {E}. hamatum ({FABRICUS}, 1782) ({E}citoninae). {W}e compiled our results with those already known in a synthetic appendix. {A} wide range of ant species react to the approach of army ant raids by evacuating their nests with several workers transporting brood. {T}he {E}citon plunder a large part of the brood but rarely kill workers or queens, so that the latter return to their nest and resume colony activity. {O}ne exception is {P}aratrechina longicornis ({LATREILLE}, 1802) colonies that quickly evacuate their nest, so that the entire colony can generally escape a raid. {A}nother is {L}eptogenys mexicana ({MAYR}, 1870) that leave their nests in columns while some nestmates resist the attack; they therefore lose only a few larvae. {W}e noted that colonies can avoid being raided if the army ants ignore them ({A}tta cephalotes ({LINNAEUS}, 1758)), or if the workers produce a repellent substance ({A}zteca associated with myrmecophytic {C}ecropia) or are repellent themselves ({P}achycondyla villosa ({FABRICUS}, 1804), {E}ctatomma spp.). {I}n the other cases, a part of the brood is lost. {W}hen an {E}citon raid approached the base of their host-tree trunk, {A}zteca andreae {GUERRERO}, {DELABIE} & {DEJEAN}, 2010 workers dropped a part of their brood on the ground. {W}hile numerous {E}citon workers were gathering up this brood, the front of the column advanced, so that the {A}zteca andreae nests were not plundered. {P}heidole megacephala ({FABRICUS}, 1793) nests were partly plundered as the workers reacted aggressively, blocking the {E}citon inside their nests during a long time. {W}hen the latter returned toward their bivouac, they were attacked and killed by their nestmates whether or not they had retrieved {P}heidole brood. {C}onsequently, the front of the column turned away from the {P}heidole nest.},
