Odor sensation is a sensory modality of considerable significance in the foraging behavior and interactionalorganization of ants. In the food bait technology, smell is the basis of attraction, which, in turn, is the line of baituse and a key parameter for judging efficacy. Yet, the currently available baits possess low attractiveness tomany ant pests. Hence, strategies to produce ant bait with increased attractiveness are needed. Despite evidencethat coffee has a diverse aroma complex that affects the behavior of honey bees and ants, its attraction to houseinvadingants has yet to be investigated. In a series of Y-tube olfactometer bioassays, we examined the behavioralresponses of Tapinoma indicum (TI), Monomorium pharaonis (MP) and Solenopsis geminata (SG) to various coffeeinducedodor stimuli, comprised of extracts from Arabica, Robusta and Liberica. All coffee extracts showed aninfluence on the behavior of TI, MP and SG workers, with Arabica showed the most significant influence to thetested ants. The workers of TI, MP and SG were more attracted to the odor of 0.01% Arabica extract (ONE), incomparison with 0.05% Arabica extract (TWO) or 0.10% Arabica extract (THREE). Arabica extract mixed withsugar (S) elicited a significant attraction from workers of all three species in a balanced competition with eitherunsweetened Arabica extract or water. These results indicated that coffee, particularly Arabica, was attractive tothe foragers of TI, MP and SG, thus, the use of coffee as a novel stimulus agent seems plausible in ant baitdevelopment.
