Complex animal societies consist of a plethora of interactions between members. To successfully thrive they must be able to recognize members and their kin, and to understand how they do this we need sufficient and reliable methods of testing. Eusocial insects are especially good at recognizing their nestmates, but the exact mechanism or how well they can discriminate is unknown. Ants achieve nestmate recognition by identifying varying proportions of cuticular hydrocarbons. Previous studies have shown ants can be trained to discriminate between pairs of hydrocarbons. This study aims to compare two methodologies previously shown to demonstrate odor learning to identify which one is the most promising to use for future odor learning experiments. The two methods tested were adapted from Sharma et al. (2015) and Guerrieri and d’Ettorre (2010). The results showed that the Guerrieri method demonstrated learning better and was more reliable and faster than the Sharma method. The Guerrieri method should be used in future experiments regarding odor learning discrimination

Across the animal kingdom, communication serves a vital purpose. The transfer of information between and among species is often paramount to many behaviors including mating, collaboration, and defense. While research has provided tremendous insight into animal communication and interaction, there is still much that we have yet to understand. Due to their reliance on interactions that maximize efficiency within their complicated colony structure and array of member roles, eusocial insects serve as an excellent model for animal communication. Among eusocial insects, ants are some of the most heavily researched, with a tremendous amount of literature focused on their cuticular hydrocarbons. Along with serving as a waterproofing agent, cuticular hydrocarbons also play a major role in recognition and communication in these insects. By studying the importance of hydrocarbons in ant social structure, their tremendously specialized olfactory system, and the use of learning assays in its study, parallels between communication in ants and other animals are revealed, demonstrating how ants serve as a relevant model for animal communication as a whole.
