Abstract
Potts and Vanderplank1 deduce a relation between the size of the pulvilli and the speed of action of contact insecticides. This would follow, as, to kill an insect, a lethal dose of the insecticide is required to be transferred to it. The larger the pulvilli, the larger the dose of insecticide the insect will collect when it alights on a treated surface. The speed of action of various modern synthetic insecticides, however, shows wide variation.
