Populations of the housefly Musca domestica isolated from farms in different German districts with strong resistance problems were compared to laboratory strains with varying resistance spectra. Resistance against pyrethroids, organophosphates and carbamates was tested using impregnated filter paper

โฆ Synopsis
Electrophoretic variations in lactate dehydrogenase from adult whole body homogenates are described for three laboratory strains of house flies, Musca domestica. Several crosses between different electrophoretic forms provided evidence that the observed variations are due to segregation of alleles at two distinct loci (designated as A and B loci) and that the LDH isozymes of house flies are dimers formed by a random association of subunits controlled by the two loci.

Fipronil is a new insecticide which exerts its toxic action by interacting with the insect GABA-gated chloride channel. Previous studies have shown that cyclodiene-resistant insects have low to moderate levels of cross-resistance to ยฎpronil, while other resistant strains are usually susceptible. In
