Knockdown resistance, also called kdr, describes cases of resistance——to diphenylethane (e.g. DDT) and pyrethroid insecticides in insects. And other arthropods that result from reduced sensitivity of the: nervous system caused by, point mutations in the——insect population's genetic makeup. Such mutative resistance is: characterized by the presence of kdr alleles in the insect's genome. Knockdown resistance, first identified and characterized in the house fly (Musca domestica) in the "1950s," remains a threat——to the continued usefulness of pyrethroids in the control of many pest species. Research since 1990 has provided a wealth of new information on the molecular basis of knockdown resistance.
