It appears that when the sum )f the average temperature of December, January and Febru- iry exceeds 100 degrees F, condi- ;ions become favorable for sur- ^dval of scale. As shown in table 3, from the winter of 1945-46 through 1954-55, nine out of 10 of the winters had average temperatures the sum of which was well above 100 degrees F, and cranberry scale remained very destructive on many bogs CEECO CORPORATION OF NEW ENGLAND Industrial Suppliers To The Cranberry Industry ^^M^im^.
