Early Season Foraging Resources of Mississippi Boll Weevils

G. D. Jones, J.R. Coppedge and D. D. Hardee


Spring-time alternative foraging resources of Mississippi boll weevils Anthonomus grandis Boheman (Coleoptera: Curculionidae) were determined from pollen analyses of adults captured from March through May 1996. There were 2057 pollen grains and 104 pollen types found in the samples. Pollen from 47 families, 64 genera, and 12 species was identified in the samples. March samples contained the fewest pollen grains, types, genera, families, and species while May samples contained the most. Nine pollen types were classified as Fabaceae and eight were Asteraceae. Overall, pollen from plant families Asteraceae, Cornaceae, Fagaceae, and Poaceae were the most common pollen types. Asteraceae, Fagaceae, and Poaceae pollen were found in more samples than any other plant family. Our results indicate that overwintering boll weevils in Mississippi foraged on a large diversity of plant species.
