Abstract
Abstract Biophysics subject covers multiple fields of physics and biology. In this research the effect of some parameters of diode laser has been experimented with ants (Camponotus consobrinus) which includes the effect on its external shape, as well as the percentage of the killing rate obtained as a result of laser radiation at a wavelength (532 nm) with power (200 mW), at distances: (10, 12, and 14 cm) between laser source and the insect, and exposure times (10, 15 and 20 sec) for each distance. The obtained results showed an increase in the rate of ant killing, as well as an increase in deformations where the distance decreased and laser exposure time increased. These results were recorded after time periods after laser treatment, which are as follows: (12, 24, 48 and 72 h). The thermal diffusion within the tissues resulting from laser radiation causes increased death rates due to damage of internal structures.
