The Effects of Conspecific Songs on the Aggression and Phonotaxic Behavior of House Crickets (Acheta Domesticus)Sendi, Kawthr (State University of New York at Fredonia, 2016-12)Mating in crickets has continued to be an especial topic because of the interesting phenomena of female mate preferences and male-male aggression. Most crickets produce three distinct song types, with each one produced under a different social circumstances. A clear understanding of the responses of crickets to different song types will help clarify the function of multiple song types. We carried out two experiments with related tests: the effect of the calling song, the courtship song, and the aggression song, on male-male aggression and on male and female phonotaxis. In the aggression experiment, we played back a single song during male-male contest, and the results showed low values of aggression intensity in the presence of calling and aggression songs. Playback songs significantly affected the duration of a fighting contest and the aggressive encounters were resolved at low intensity compared to muted treatment. In the phonotactic experiment, we played a single song and female crickets showed non-significant tendency to respond less to the courtship song compared to the aggression and calling songs. Overall, the results show no significant phonotactic preference for both male and female crickets.
