Ecology and genetics of insecticide resistance in Helicoverpa armigera: interactions between selection and gene flow



Ecology and genetics of insecticide resistance in Helicoverpa armigera: interactions between selection and gene flow



Genetica (Dordrecht): 902-3: 217-226



Factors important in the evolution of resistance to pyrethroid insecticides in the noctuid Helicoverpa armigera are reviewed. Although 3 mechanisms are involved in the evolution of resistance, present-day fluctuations in phenotype frequency can be explained by variation in only one of these, metabolic resistance, that is inherited as a single, incompletely dominant gene, mfo. Selective mortality of phenotypes occurs in both larvae and adults in the presence of pyrethroid insecticides.
