The Mechanism of Absorption of Sodium Fluoride by Roaches

Buy Article:


A technique is described whereby individual roaches (Periplaneta americana, Blatta orientalis) are strait jacketed and the fluoride applied to various parts of the body. The data so obtained is supplemented by dipping tests. The evidence all indicates that sodium fluoride can be absorbed directly through the body integument of the insect, especially through the membranous areas of the body wall, such as the junction of the head and thorax and also the region of the coxae. The large area of absorption necessary to take up enough fluoride to kill the insect would indicate that in actual practice the roach must absorb some of the toxic material by licking it off the body appendages.
