Influence of protein on feeding behavior of Ceratitis capitata Wiedemann (Diptera: Tephritidae): comparison between immature males and females
[en]The objective of this work was to compare the influence of dietary protein on performance and feeding behavior of immature males and females of Ceratitis capitata (Wiedemann). The protein source was beer yeast at 6.5 and 1.5 g.100 ml-1. The following parameters were evaluated: percentage of emergence, total life cycle, adult size, diet consumption, feeding preference and discrimination threshold for yeast. Immature adults showed similar protein requirements regardless of sex. Both males and females showed similar feeding behavior, preferring to feed on the diet with higher protein content. The discrimination threshold for levedure in both sexes was 0.4 g.100 ml-1. We concluded that immature males of C. capitata show similar protein requirements as the immature females. (author)
