Boll weevil: Winter survival in surface woods trash in Mississippi
Environmental Entomology 10 (3), 419-423
Abstract: During the period 1955-1973, winter survival of the boll weevil, Anthonomus grandis Boheman in Mississippi, as determined by examination of surface woods trash samples in the fall and spring, ranged from 0.2 to 51.6% for a state avg. The numbers of weevils entering hibernation in the fall ranged from 0 to 72,149/ha. In most years percentage survival was greater at the southern end of the study than at the northern end. Several climatic factors (minimum temperature, number of days during which the minimum temperature was 0°C or below, number of days during which the maximum temperature was 0°C or below) were correlated with survival percentage.
