The temperature is probably not the only variable that affected the crickets' chirping. The results could have been due to the fact that there were no females or because they were under stress.
(http://www.msue.msu.edu/msue/imp/mod02/01500542.html). Our poster contains graphs that show how much male crickets chirp in 0C and 40C, and also the chirping at 25C, which was our control group. Our hypothesis was not supported by our experiment, so this shows that the male crickets do not chirp more in warmer weather. .
Acheta domesticus, is a European species, which is commonly called the house cricket. These crickets are reared in enormous numbers commercially as bait for fishing and are sold by pet stores as food for various insect-eating animals. These crickets are also known to be pests in and around buildings. There are a lot of studies on the Internet about how the Acheta domesticus crickets are affected by different temperatures. These experiments show that male crickets are expected to be more active in warmer temperatures. They also showed that the ideal temperature for them to live and be active in is 30 Celsius. One of these studies was found at (http://www.ex.ac.uk/bugclub/cricket.html). .
The calling sound is basically the conspicuous chirping sounds made by males. Past research showed that male field crickets produce three types of acoustic signals: aggressive chirps, which are used in male-male fights; calling songs used to attract females; and courtship song, used directly prior to mating once a female has been located by a male. (Gray 1996).
The purpose of this poster is to study effects of temperatures on male crickets. In this poster, we will show graphs that illustrate the results of the crickets' response to various temperatures. The results shown on this poster helped us determine whether our hypothesis was supported. Our hypothesis being that male crickets chirp more when exposed to warmer temperatures compared to when they are exposed to colder temperatures.
