In a study of the population dynamics of Diaprepes abbreviatus (L.) made from June 1970 to December 1973, weekly sampling in a 55-acre grove showed that more adults were present August to December. However, weevils were generally present throughout the year. Heavy rainfall generally preceded increased adult emergence. The ♀:♂ ratio of weevils collected during 1972 and 1973 was 55.6:44.4 and 59.1:40.9, respectively. An overlapping of generations occurs in Florida, and the subterranean larvae, the most injurious stage, enter the soil throughout the year.
