Abstract
An insect barrier permitting the downward travel of insects, particularly gypsy moths, over the barrier but preventing insects from travelling upwardly over the barrier. The barrier comprises a contact means for engagement with a tree and a cylindrical portion spaced apart from the tree by the thickness of the contact means. Within the interior of the barrier is a means for preventing the travel of insects. A downwardly sloped conical portion is provided, preferably above the cylindrical portion, having an outer surface permitting the travel of insects thereon. Gypsy moth larvae are permitted to pass over the insect barrier in their daily migration down the tree, but are prevented from ascending past the barrier to re-infest the tree.
