STUDIES ON REPELLENTS FOR BITING FLIES

Abstract

In view of the known lack of effectiveness and doubtful value of many of the materials cited in literature as being of value as repellents for biting flies, a series of experiments was carried out at the direction of the Dominion Entomologist, during the past three seasons, with the object of determining which of the many materials recommended as repellents might be the most effective and which the most lasting in effect.
