Abstract:A method was developed to measure areas of incomplete removal of cotton, Gossypium, leaf tissue by Bucculatrix thurberiella Busck. By use of the diazo process, black and white transparencies were made of the leaves. Damaged areas appeared transparent or nearly so. The leaf images were read on an optical area meter. After opaquing the damaged areas with masking tape or black lacquer, the areas were read again and the leaf damage was obtained from the area differences. This method may be used to measure similar damage caused by other insects.
