pheromone
t. "rugatulus" ants also use chemical signaling for communication. similar taxa of ants related to the t. "rugatulus" emit a chemical signal from their mandibular gland. this specific chemical’s name is 2,5-dimethylpyrazine. like many chemicals, t. "rugatulus" use this chemical for different reasons and the context in which the chemical is received by another individual will give it clues as to its current situation. t. "rugatulus" ants use such chemicals as trail pheromones. the location of the chemical in relation to the nest was extremely important in their behavioral responses. when an alarm signal was presented far away from the nest, the ants were reported to run away from the scent, whereas if the chemical was present just outside their nest, they would run towards it. it is thought that ants may interpret the close alarm signal as a cry for help and attempt to save whoever was emitting the chemical.
