ABSTRACT
The Musca domestica is a serious hygienic pest of poultry, humans, and livestock facilities with the immense ability for resistance development against chemical insecticides. The current study aimed to evaluate the susceptibility and resistance status of M. domestica against different classes of insecticides. For this purpose, adult M. domestica populations were collected from five different localities of Sargodha division (Sargodha, Khushab, Jauharabad, Mianwali, and Bhakkar), Punjab, Pakistan, and tested against selected insecticides. The resistance ratios (RR) at LC50 ranged from 10.32-35.37 folds for deltamethrin, 17.49-38.13 folds for fipronil, and 10.70-18.81 folds for chlorpyrifos. The RR values at LC50 for imidacloprid and pyriproxyfen ranged from 4.35-28.0 and 10.56-21.45 folds, respectively. The study showed varying levels of resistance in M. domestica populations from area to area and from insecticide to insecticide. Therefore, to control resistance development in M. domestica from livestock facilities, inappropriate and excessive use of insecticides must be controlled through proper mechanisms and strategies.
