Behavioral Repertory of Adult Cylas formicarius (Fabricius) (Coleoptera: Brentidae)

Abstract

Adult female and male sweetpotato weevils, Cylas formicarius (Fabricius), have repertories of at least 19 and 21 behavior patterns, respectively. These are described and named, including eight self-grooming patterns. Consistent with the species' slight sexual dimorphism, few behavior patterns are peculiar to one sex. The sequence of self-grooming movements is analyzed for each sex. Comparative assays of vagility and overall activity do not show any difference between the sexes.
