| Abstract | ||
| The karyotype of field & laboratory strains of OWSWF, Chrysomya bezziana was investigated. The results of this investigation showed that this species has six pairs of chromosomes (2n = 12), which consist of five pairs of autosomal chromosomes and a pair of sex chromosome. The average length of autosomal chromosomes of the field & laboratory strains were 4.03, 3.77, 3.46, 3.05, 2.41, &4.00, 3.68, 3.38, 2.98, 2.53 mmfor chromosomes numbers 2, 3, 4, 5& 6 respectively, while for the sex chromosome, it was difficult to be measured because they form what is like parachute shape. Furthermore, in this investigation the arm & centromere indeces were also measured for field & laboratory strains. Lastly , the results of different mating between these two strains of Ch. bezziana showed that they were belong to species Ch. bezziana. | ||
