Prospects for the use of baits based on modern active ingredients against house flies

Topical application revealed the high resistance of field populations of houseflies to pyrethroids (500–900?), neonicotinoids (345–500?), phenylpyrazoles (46–75?), susceptibility to FOS (0.6–1.4?) and oxadiazines (0.2?). With intestinal exposure, resistance rates are somewhat lower, but resistance remains at a high level to fipronil (33–76?), thiamethoxam (80–105?) and clothianidin (80–98?). Susceptibility to indoxacarb (0.2–1.4?) was revealed. The comparative efficacy of two modern baits based on indoxacarb and dinotefuran for resistant and susceptible strains of house flies was studied. Both insecticides are highly toxic to house flies in the form of commercially available baits. Indoxacarb and dinotefuran can be recommended for introduction into rotation schemes of insecticides in the form of food baits to control adult flies.
