Abstract
The ova of Nematocerus sp. (nr. Brevicornis Hust.) are usually laid on leaves of cereals or other Gramineae in a fold made by the female weevil [1]. Although the fold is sealed with a layer of adhesive secreted by the abdomen of the female, there was a possibility that the application of insecticide would cause heavy mortality in the egg mass and, since control of the larvae presented considerable difficulties, such a possibility was obviously worthy of test. To this end, four laboratory tests were conducted and subsequently one small and one large field trials were laid down.
