Extract

The usual criterion of insectidal effectiveness is the mortality suffered by test insects exposed to insecticides. Often, investigators disregard the sex ratio when selecting test insects for exposure. Demonstrated differences in susceptibility between male and female insects require evaluation of the sex ratio in studies on insecticidal effectiveness.
