The Perispiracular Glands of Mosquito Larvae

Abstract
1. Perispiracular glands are present in the larvae of Anopheles and Culex.2. These glands secrete an oily substance which is responsible for the hydrofuge properties of the spiracular region of mosquito larvae.3. The differential wetting of the spiracular region and the action of oil on mosquito larvae depend on the presence of this oily secretion.
