Rassoul Amir Fattahi, Hossein Zamanian Bijan Hatami Abstract Department of Entomology, To study the calling songs in cicada Chloropsalta smaragdula and its relationship with body length, Khorasgan (Isfahan) Branch, width, and weight, a research was conducted in the Iranian city of Mobarakeh, Isfahan Province, in 2011- Islamic Azad University, Isfahan, 2012. Different sound samples were taken under field and laboratory conditions. Throughout the Iran. sampling period, the calling songs of nine male cicadas were recorded and studied. The sound of each individual cicada was separately analyzed by MATLAB Software, and the size of its main parameter Alireza Jalali Zand Department of Entomology, (i.e., dominant frequency) was determined and recorded. The results showed that this cicada species have Khorasgan (Isfahan) Branch, a mean dominant frequency of 9.121 kHz. Moreover, the correlation coefficients indicated that there is a Islamic Azad University, Isfahan, positive relationship between the dominant frequency for the audio signal of the calling songs with body Iran. width and weight, and is significant at p<0.0001 probability level, thus, indicating that dominant frequency increases as body width and weight increase.
