Most frequently inquiries have been coming from Cache and Box Elder counties. However infestations have been reported as far south as Millard county, and observed in Tooele, Davis and Salt Lake counties he said. Farmers are urged to destroy first generation army w o r m s j wherever possible. "Control of worms now is important if we are to reduce injury from the second generation worms which normally appear during late July and August," Dr. Knowlton said. "If the spring .generation worms are not permitted to mature, a substantial decrease in crop injury may be expected. Some control, due to a disease of these worms, has been discovered in parts of Cache valley by Professor C. J. Sorenson of the college entomology department and F. V. Lieberman of the U. S. bureau of entomology and plant quarantine. "The extent of benefit which can be depended on from this beneficial disease of army worms, or how widespread its occurrence, is not as yet fully known," he concluded.
