The most serious outbreak of the gypsy moth, Porthetria dispar on record occurred in the summer of 1953 when nearly 1.5 million acres of New England woodlands were defoliated by this pest. Much of the defoliation occurred for the 1st time in areas w. of the principal Berkshire and Green Mountain elevations. There was apprehension at the time that existing high populations in this area, located only a few miles from the w. limits of general infestation, would result in considerable spread of the moth into previously uninfested territory. These fears were amply justified as demonstrated by the results of detection surveys conducted in succeeding years.
