This study shows that moderate caffeine exposure improves learning in Argentine ants during foraging tasks, but not homing behavior, with dose-dependent effects.

This study shows that Argentine ants avoid food scented with conspecific corpses but not when corpses have ingested toxicant, suggesting potential strategies for bait management.

This study assesses cognitive bias and emotional contagion in ants using a judgment bias task, finding optimism but no emotional contagion.

This study tests the effects of seven neuroactive chemicals on spatial and olfactory learning in invasive Argentine ants, finding no significant impact on learning abilities.

This study shows that bundling affects pheromone deposition (liking) but not odor choice (wanting) in ants, revealing a dissociation between liking and wanting in an insect.

This study shows bumblebees can distinguish sucrose solution from water at a distance, suggesting spectral differences are the primary mechanism for this discrimination.

This study examines learning in Argentine ants, showing rapid short- and long-term memory development and efficient information transfer, suggesting potential for improving bait uptake in pest control.

This study shows that lower light levels in Lasius niger ants lead to increased pheromone trail deposition and greater reliance on pheromone trails when visual information is less reliable.

The paper shows ants exhibit relative value perception, adjusting food acceptance based on prior experience and social cues, with implications for collective decision-making.

This study shows ants exhibit assimilation effects in food value perception when odour cues are present, aligning value with expectations rather than contrasting against them.

This study shows that individual ants exhibit strong risk aversion in foraging decisions, supporting perceptual mechanisms over rational decision-making models.

The paper shows that small differences in learning speed based on food quality and foraging motivation can drive efficient collective foraging in ant colonies, with implications for understanding group behavior without social interaction.
