ABSTRACT
The house fly (Musca domestica) is a pest that acts as a vector of various diseases. Chemical insecticides are used on large scale for the effective and quick management of this pest but it has developed resistance against various insecticides in many countries of the world. This study was designed to check the resistance in M. domestica against selected insecticides from Bhalwal as no previous work has been reported from this area. Flies were collected from two different localities i.e., location 1 (L1) was Chak 07 SB Bhalwal (32°14’52.3”N 72°55’25.5”E) and location 2 (L2) was Chak 02 NB Bhalwal (32°19’20.1”N 72°54’56.5”E), Punjab, Pakistan. The flies were reared in mesh-cages and maintained on an artificial diet in the lab. Lab strain flies were collected from area where minimum insecticides were used. Flies from the F1 generation were used in the bioassays. The results showed that LC50 for the lab strain against bifenthrin and dimethoate was 11.068 µg/ml and 8.879 µg/ml, respectively. LC50 for field strains, Bhalwal L1 and L2, against bifenthrin was 96.184 µg/ml and 130.903 µg/ml, respectively whereas against dimethoate it was 74.340 µg/ml and 84.531 µg/ml, respectively. The resistance ratios for field strains of locations 1 and 2 against bifenthrin were 8.690 fold and 11.827 fold, respectively whereas these were 8.372 fold and 9.520 fold against dimethoate, respectively. In conclusion, the study revealed varying levels of resistance to bifenthrin and dimethoate that suggest cautious application of these pesticides for the control of M. domestica.
