Aceitação e preferência de frutos para oviposição em duas populações de Ceratitis capitata (Diptera, Tephritidae) Iheringia, Sér. Zool.
Joachim-Bravo,Iara Sordi; Silva-Neto,Alberto Moreira da.
The influence of four host fruits, orange (Citrus sinensis L.), papaya (Carica papaya L.), mango (Mangifera indica L.) and apple (Malus domestica Borkh) on oviposition behavior of Ceratitis capitata (Wiedemann, 1824) was evaluated. Experiments were carried out on two C. capitata laboratory-reared populations: one with artificial diet for 10 years with periodic introduction of wild flies and other reared with artificial diet for 20 years without wild flies introduction. In acceptance experiments two pieces of a single fruit type were exposed to a group of 10 females; after 48 hours, these were changed by two new pieces of the same fruit type, and, in the end of the fourth day, the experiments were concluded. In preference experiments, two pieces of...

The relevance of age and nutritional status on the mating competitiveness of medfly males (Diptera: Teprhitidae) Rev. Bras. Zool.
Roriz,Alzira Kelly Passos; Joachim-Bravo,Iara Sordi.
Results of previous investigations trying to ascertain which physiological factors are more important to the mating success of medfly males are controversial. In part, this controversy owes to the fact that each factor was evaluated by an independent study using different experimental designs and populations. In the present study we compare the roles of age and nutritional status (immature and adult phases) on the mating competitiveness of Ceratitis capitata (Wiedemann, 1824) males. Three parameters were used to evaluate the male mating success: calling behavior (pheromone emission), lek participation and copulation (ability to be chosen by a female). Females gave preference to the males that were given a high protein diet in the larval phase. By contrast,...

The role of protein in the sexual behaviour of males of Ceratitis capitata (Diptera: Tephritidae): mating success, copula duration and number of copulations Rev. Bras. Zool.
Joachim-Bravo,Iara Sordi; Anjos,Cyntia Santiago; Costa,Anne Moreira.
In this paper, we investigated the influence of protein ingestion during the early adult phase on the sexual behavior of males of Ceratitis capitata (Wiedemann, 1824). The following parameters were evaluated: mating success (ability to be chosen by females), number of copulations, and copula duration. Experiments were carried out using a fifteen-year old laboratory lineage with the occasional introduction of wild flies. Two groups of adult males fed a high-protein diet during their larval phase were given either a high-protein diet (based on Brewer's yeast, concentration = 6.5 g/100 ml) or a no-protein diet. Both groups of males were exposed to females fed either a high-protein diet or a no-protein diet and were subsequently evaluated for the parameters...

Mass-rearing of Mediterranean fruit fly using low-cost yeast products produced in Brazil Scientia Agricola
Silva Neto,Alberto Moreira da; Santos,Tatiana Rodrigues de Oliveira; Dias,Vanessa Simões; Joachim-Bravo,Iara Sordi; Benevides,Leandro de Jesus; Benevides,Clicia Maria de Jesus; Silva,Mariangela Vieira Lopes; dos Santos,Deise Cristina Campos; Virgínio,Jair; Oliveira,Givanildo Bezerra; Walder,Julio Marcos Melges; Paranhos,Beatriz Aguiar Jordão; Nascimento,Antônio Souza do.
Ceratitis capitata is one of the most important pests of fruits for exportation, and Sterile Insect Technique (SIT) has been the most efficient and environmental friendly technique used to control fruit fly populations around the world. A key goal in achieving a successful SIT program is a mass rearing system producing high quality insects at low cost. Providing adults with an artificial diet containing hydrolysed protein has been the major obstacle for bio-production facilities in Brazil, because it is expensive and has to be imported. Two other commercial products, autolysed yeast (AY) and yeast extract (YE), of domestic origin and low cost, were tested as substitutes of the imported hydrolyzed protein. To compare their efficiency we observed the female...

Adding guarana powder to medfly diets: an alternative for improving the Sterile Insect Technique Scientia Agricola
Aquino,Jamile Câmara de; Souza,Cassius Fabian Costa; Santos,Jânio Rodrigo de Jesus; Joachim-Bravo,Iara Sordi.
ABSTRACT Ceratitis capitata (medfly) is a globally important horticultural pest that can be controlled using the sterile insect technique (SIT), but the success of SIT depends on the sexual performance of mass-reared males when released into the field. We added “guarana” (Paullinia cupana) powder (derived from an Amazonian fruit that is considered to be a stimulant with aphrodisiac effects, capable of improving human physical stamina) to the diets of adult male medflies to determine whether it increased their sexual performance. The basic diet of a protein extract + sucrose (1:3) was enriched with guarana powder (3 % on a volume basis). Experiments examining sexual competitiveness were performed using lab-reared males fed with the enriched diet vs....

Oviposition preference and larval performance in Ceratitis capitata (Díptera, Tephritidae) Zoologia
Joachim-Bravo,Iara Sordi; Zucoloto,Fernando Sérgio.
Experiments concerning oviposition preference were carried out on Ceratitis capitata to determine whether females are able to preferentially oviposit on natural hosts in which the larvae develop better. The results indicated that the females do not preferentially oviposit on hosts of better nutritive value for the larvae.
