Egg Distribution and Sampling of Diaprepes abbreviatus (Coleoptera: Curculionidae) on Silver Buttonwood

Jorge E. Pena, D. Amalin, A. Hunsberger, C. Mannion

Abstract


Taylor’s power law and Iwao’s patchiness regression were used to analyze spatial distribution of eggs of the Diaprepes root weevil, Diaprepes abbreviatus (L.), on silver buttonwood trees, Conocarpus erectus, during 1997 and 1998. Taylor’s power law and Iwao’s patchiness regression provided similar descriptions of variance-mean relationship for egg distribution within trees. Sample size requirements were determined. Information presented in this paper should help to improve accuracy and efficiency in sampling of the weevil eggs in the future.
