IT has been suggested from time to time that the pore canals of the insect cuticle offer an important channel for the entry of contact insecticides, and Wigglesworth1, working on the bug Rhodnius, in which the canals contain protoplasmic filaments, or perhaps fluid, has recently given additional evidence in favour of this view. But Richards and Anderson2, as a result of their electron microscope studies of the cockroach cuticle, believe that the pore canals are filled by a watery fluid and not by protoplasm, and that oil-borne insecticides cannot penetrate by this route. Among earlier writers Holmgren3, Plotnikow4, and Berlese5have expressed the view that although the canals are occupied by protoplasm during early growth of the cuticle, they are later filled by some cuticular substance. If this is so, they would appear scarcely likely to be involved in insecticide penetration.
