Characterisation of malathion resistance mechanisms and stress responses of susceptible and resistant strains of red flour beetle Tribolium castaneum (Herbst)

The extensive use of insecticides to control insect pests has provided a dramatic illustration of evolution in natural populations. Malathion resistance in the red flour beetle, Tribolium castaneum (Herbst), is a worldwide problem and is very stable once it becomes widespread in natural populations....
