| Abstract | ||
| According to global-wide presence of insecticides resistance to pyrethroids, the current study identified the purpose to detect the allelic genotypes regarding this issue in house flies in Iraq. From the governorate of Al-Qadisiyah, Iraq, 60 morphologically and molecularly recognized house flies were caught from 6 different regions. Using a technique called polymerase chain reaction (PCR) amplification of specific allele (PASA), PCR was employed to reveal the presence of allele-genetic variations in the para-type sodium channel (para) gene to recognize knockdown resistance (kdr) mutation from the homozygous-wild type of complete susceptibility (sus/sus) to the mutated-homozygous type of complete resistance (kdr/kdr) or to the mutated-heterozygous type (kdr/sus). Here, these genotypes were targeted using specific primers to identify these genetic variations. The results have declared the presence of the sus/sus at 100%-frequency rate in all flies, and none of the other genotypes were detected (0%) in all flies. This valued piece of result indicates the reality of resistance persistence due to lack of insecticide-spraying programs in the governorate. This study provides high-quality information about the current status of insecticide resistance in house flies in Iraq about supporting the fact of genetic-base development of such resistance via frequent use of insecticides. | ||
