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...

Occurrence of Wolbachia in Brazilian samples of Ceratitis capitata (Wiedemann) (Diptera: Tephritidae)

Autores: Rocha,Lincoln S.; Mascarenhas,Rodrigo O.; Perondini,André L.P.; Selivon,Denise.
Wolbachia bacteria were detected by PCR followed by sequencing of a fragment of the 16S ribosomal gene, in a natural population sample and in two laboratory colonies of the medfly, C. capitata (Wied.), from Brazil. Sequencing revealed that the fragment was compatible with the Wolbachia type A group found in several insect species. This is the first description of a natural Wolbachia infection in C. capitata, since several other samples from different regions so far analyzed seemed to be free of infection.

Importância da ingestão de proteína na fase adulta para o sucesso de acasalamento dos machos de Ceratitis capitata Wiedemann (Diptera: Tephritidae)
Provedor de dados: 82
Autores: Silva Neto,Alberto M da; Dias,Vanessa S; Joachim-Bravo,Iara S.
The importance of the protein ingestion during the adult stage on the mating success of males of Ceratitis capitata Wiedemann was evaluated in experiments of laboratory and field cage. In laboratory, the effects of protein ingestion during the first four or 12 days of the male adult life was assessed by the following parameters: mating success (capacity of being chosen by the female) and the number of males that give out pheromonal signals. Some experiments of mating success had been carried through with males in different ratios. In these tests, the number of males which had ingested protein (an unique male) was remained constant and the number of males fed without protein was gradually increased from 1:1 to 1:5. In the field cages, the mating success...

Influence of different tropical fruits on biological and behavioral aspects of the Mediterranean fruit fly Ceratitis capitata (Wiedemann) (Diptera, Tephritidae)

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...
