Resistance of musca domestica [L.] [diptera: muscidae] from gamasa city to some insecticides

ABSTRACT

Susceptibility tests for house fly Musca domestica collected from Gamasa City and laboratory bred 1 were carried out. The data suggested that the levels of resistance in Gamasa population against malathion, diazinon, dimethoate [organophosphorus compounds] and permethrin [pyrethroid 1] were developed, while deltamethrin and cypermethrin were still effective. The highest homogeneity response was for malathion, followed by dimethoate, deltamethrin and cypermethrin. On the other hand, the highest homogeneity response in laboratory population was that of cypermethrin and deltamethrin followed by malathion, dimethoate, permethrin and then diazinon. The EST activity was higher in laboratory population [3 heavy bands], than Gamasa one [2 faint bands], while the activity of LDH and G-6PDH were higher in Gamasa population than in laboratory one. The ADH activity was the same in both populations. This means that EST was not the main detoxifying target in Musca domestica
