Oviposition preference hierarchy in Ceratitis capitata (Diptera, Tephritidae): influence of female age and experience
Provedor de dados: 76
Autores: Joachim-Bravo,Iara S.; Fernandes,Odair A.; Bortoli,Sérgio A.; Zucoloto,Fernando S.
The influence of two factors, age and previous experience, on the oviposition hierarchy preference of Ceratitis capitata (Wiedemann, 1824) females was studied. Two populations were analyzed: one reared in laboratory during 17 years and the other captured in nature. In the first experiment the oviposition preference for four fruits, papaya, orange, banana and apple was tested at the beginning of oviposition period and 20 days past. The results showed that the wild females as much the laboratory ones had an oviposition preference hierarchy at the beginning of peak period of oviposition. However this hierarchic preference disappeared in a later phase of life. In the second experiment the females were previously exposed to fruits of different hierarchic...

Influence of protein on feeding behavior of Ceratitis capitata Wiedemann (Diptera: Tephritidae): comparison between immature males and females
Provedor de dados: 82
Autores: Plácido-Silva,Maria do C.; Zucoloto,Fernando S.; Joachim-Bravo,Iara S.
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...

Effects of different protein concentrations on longevity and feeding behavior of two adult populations of Ceratitis capitata Wiedemann (Diptera: Tephritidae)
Provedor de dados: 82
Autores: Plácido-Silva,Maria do Carmo; Silva Neto,Alberto M. da; Zucoloto,Fernando S.; Joachim-Bravo,Iara S.
The effects of protein intake on two adult male and female populations of Ceratitis capitata Wiedemann were assessed. One population consisted of flies reared for twenty years in the laboratory (Lab-pop); the other population consisted both of flies reared in the laboratory for approximately fifteen years and of the periodically introduced wild flies (Hybrid-pop). Three diets were tested: a no-yeast diet and two diets containing yeast (protein source) at the concentrations 6.5 g or 1.5 g per 100 ml diet. The parameters analyzed were: adult longevity, diet intake with and without yeast, and discrimination threshold for yeast. Protein intake increased Lab-pop adult longevity and did not affect longevity of the Hybrid-pop. Longevity in each population was...

Longevity and fecundity of four species of Anastrepha (Diptera: Tephritidae)
Provedor de dados: 82
Autores: Joachim-Bravo,Iara S.; Magalhães,Tatiana C.; Silva Neto,Alberto M. da; Guimarães,Analice N.; Nascimento,Antônio S.
Studies on fruit fly longevity and fertility are important to understand their demographic aspects and to orient implantation of integrated management strategies. This study investigated the longevity of adult Anastrepha species A. fraterculus (Wiedemann), A. sororcula (Zucchi), A. zenildae (Zucchi) and A. obliqua (Macquart). The reproductive pattern was also assessed throughout the life of the species A. sororcula and A. obliqua and fertility at eighteen days of life of the four species. A. zenildae longevity was similar to A. sororcula, longer than A. fraterculus and followed by A. obliqua. No statistical difference between the sexes was observed, except for A. obliqua. The decrease in survival occurred fastest in A. obliqua followed by A. fraterculus...

Influence of different tropical fruits on biological and behavioral aspects of the Mediterranean fruit fly Ceratitis capitata (Wiedemann) (Diptera, Tephritidae)
Provedor de dados: 92
Autores: Costa,Anne M.; Amorim,Francismare de O.; Anjos-Duarte,Cyntia S.; Joachim-Bravo,Iara S.
Influence of different tropical fruits on biological and behavioral aspects of the Mediterranean fruit fly Ceratitis capitata (Wiedemann) (Diptera, Tephritidae). Studies on Ceratitis capitata, a world fruit pest, can aid the implementation of control programs by determining the plants with higher vulnerability to attacks and plants able to sustain their population in areas of fly distribution. The objective of the present study was to evaluate the influence of eight tropical fruits on the following biological and behavioral parameters of C. capitata: emergence percentage, life cycle duration, adult size, egg production, longevity, fecundity, egg viability, and oviposition acceptance. The fruits tested were: acerola (Malpighia glabra L.), cashew (Anacardium...
