Abstract

The flight of filbertworm moths during the early 1956 season was very small when compared to 1954 or to 1955 but after mid-July the moth catch—in five bait pans in an experimental walnut orchard near Gridley—began to mount. By season's end the severity of the infestation was second to that of 1954, when the infestation was the most severe encountered since investigations were started in 1944.
