Effect of laser radiation on different stages of Drosophila melanogaster

Abstract

The effect of different doses of laser on some biological aspects of Drosophila melanogaster exposed as larvae of 3days and pupa of 1days old were studied . Both laser have significant effect on the larvae, pupa period emerged adults and life span of emerged adult. The result showed that the percentage of death in larva exposed to radiation were 5, 10, 5, 30, 25, 25 and 30% when exposed to doses 1, 2, 3, 4, 5, 6, 7 minutes respectively compared to control 0%, the number of adults emerging were 75,55,85,45,25,40 and 45% respectively compared to control 100%.The pupa to doses of radiation 8, 10, 12, 14, 16, 18 minutes reach the percentage of death of 5, 25, 25, 15, 15 and 30% respectively compared to control 0% and emergence percentage of natural adult of 85, 65, 75, 80, 85 and 70% respectively compared with control was 100%.
