摘      要：Argentine ants Linepithema humile are one of the most damaging invasive alien species *** or disrupting cognitive abilities,such as learning,has the potential to improve management efforts,for example by increasing preference for a bait,or improving ants ability to learn its characteristics or ***-feeding insects are often the victims of psychoactive manipulation,with plants lacing their nectar with secondary metabolites such as alkaloids and non-protein amino acids which often alter learning,foraging,or ***,the effect of neuroactive chemicals has seldomly been explored in ***,we test the effects of seven potential neuroactive chemicals-two alkaloids:caffeine and nicotine;two biogenic amines:dopamine and octopamine,and three nonprotein amino acids:β-alanine,GABA and taurineon the cognitive abilities of invasive *** using bifurcation *** results confirm that these ants are strong associative learners,requiring as little as one experience to develop an ***,we show no short-term effect of any of the chemicals tested on spatial learning,and in addition no effect of caffeine on short-term olfactory *** lack of effect is surprising,given the extensive reports of the tested chemicals affecting learning and foraging in *** mismatch could be due to the heavy bias towards bees in the literature,a positive result publicationbias,ordifferences inmethodology.
