Nerve Sensitivity and Resistance to DDT in Houseflies

The sensitivity of the central nervous system to the direct action of DDT was compared among three strains of houseflies. The threshold concentration of DDT for inducing motor discharges of impulses in the leg was taken as a measure of nerve sensitivity. It was found that there is a close parallelis...

Summary:The sensitivity of the central nervous system to the direct action of DDT was compared among three strains of houseflies. The threshold concentration of DDT for inducing motor discharges of impulses in the leg was taken as a measure of nerve sensitivity. It was found that there is a close parallelism between mortality and nerve sensitivity; nerve sensitivity is highest in the highly susceptible strain, itis moderate in the moderately susceptible strain, and it is lowest in the resistant strain. It is concluded that the nerve sensitivity to DDT plays an important role in resistance.
