“…The results of the present study were in agreement with their results by showing the anterior pole as inverted and cup-shaped. Mouzaki and Margaritis (1987) reported that respiratory structures in drosophilids (Emmart, 1933;Norrbom, 1985;Headrick and Goeden, 1990;Murillo and Jirón, 1994). In addition to these findings, the present study showed that there were clear differences in the external morphology of B. oleae eggs during embryogenesis, as demonstrated by in vivo photographic illustrations of eggs 1-60 h after oviposition.…”

The olive fruit fly, Bactrocera oleae (Rossi) (Diptera: Tephritidae), is a pest that infests olive fruits. The female oviposits in large green olives and larvae hatch inside the fruit, where they feed upon the fruit tissues. Larval development is completed inside the fruit. These flies cause great damage to olive production worldwide. Traditionally, insecticides have been directed against the adult stage, but the results are not efficient. This present work is a study of embryogenesis in the olive fruit fly. The external morphology of the Bactrocera oleae Rossi (Diptera: Tephritidae) egg is described from light microscopy without dechorionation. The observations were made in vivo and were photographed. The eggshell of B. oleae contains a smooth chorion with a cup-shaped anterior pole. The average length of eggs is 0.738 ± 0.01 mm and the average diameter is 0.21 ± 0.06 mm. The embryonic developmental progress is described as formation of the zygote, blastoderm and gastrulation, and organogenesis. The embryogenesis is completed within 65-70 h at 25 ± 1 °C under laboratory conditions. External egg morphology can be useful in estimating the age of B. oleae eggs for purposes such as introducing genes into embryos by germline transformation in future studies.

“…Although being similar to other Anastrepha species in the fraterculus group, as Þrst described by Emmart (1933) and subsequently using SEM by Carroll and Wharton (1989), Murillo and Jiró n (1994), and Selivon and Perondini (1998), the eggshell sculpturing shows some speciÞc characters for the six species examined in this study.…”

“…To date, the eggs of only 25 species of Anastrepha have been described and most of these studies document only simple aspects of egg morphology such as length and width as seen by a light microscope (Emmart 1933, Seṍn 1933, Lawrence 1979, Steck and Malavasi 1988, Steck and Wharton 1988, Carroll and Wharton 1989, Norrbom et al 1999. There are published studies of eggs for Þve species of the fraterculus group but detailed scanning electron microscopic (SEM) images have been provided only for the Anastrepha fraterculus (Wiedemann) complex (Murillo and Jiró n 1994;Perondini 1998, 2000;Perondini and Selivon 1999;Selivon et al 2003), Anastrepha ludens (Loew) (Carroll andWharton 1989, Norrbom et al 1999), Anastrepha obliqua (Macquart) (Murillo and Jiró n 1994), Anastrepha serpentina (Wiedemann), and Anastrepha sororcula Zucchi .…”

We describe detailed scanning electron microscopic (SEM) observations of eggs of six Anastrepha species in the fraterculus group: Anastrepha antunesi Lima, Anastrepha bahiensis Lima, Anastrepha coronilli Carrejo & González, Anastrepha distincta Greene, Anastrepha turpiniae Stone, and Anastrepha zenildae Zucchi, for the first time. Eggs were dissected from females captured in McPhail traps in Cariri in the state of Tocantins; Itacoatiara, Manaus, and Presidente Figueiredo in the state of Amazonas; and Porto Velho in the state of Rondônia, in the Brazilian Amazon. Eggs were examined using both scanning electron and optical microscopes. At least 10 eggs were examined for each species by using SEM, and 20–35 eggs per female of at least three females of each species were prepared for light microscopy. The eggs of all six species are similar in gross morphology. They are tapered at both ends, have a papilla at the anterior pole, and the micropyle is located on the dorsal side near the anterior pole. Diagnostic characters to differentiate among these six species include the chorion ornamentation, location of aeropyles, and a pronounced rim of the chorion with a woolly appearance surrounding the micropyle. None of the eggs of the studied species had a conspicuous respiratory appendage.

“…Murillo and Jirón (1994) found that A. obliqua showed greater oxygen demand by depositing their eggs in a way that the respiratory appendages remain outside of the fruit. However, Margaritis (1985) believes that species such as A. serpentina and C. capitata can oviposit in greater depth due to an air chamber in eggs, which would not require immediately atmospheric oxygen.…”

Oviposition of fruit flies (Diptera: Tephritidae) and its relation with the pericarp of citrus fruits

Fruit flies (Diptera: Tephritidae) represent a threat to fruit growing worldwide, mainly the citrus culture, however, biological studies show that fruit flies are not perfectly adapted to this host. This study investigated oviposition of Anastrepha fraterculus (Wiedemann, 1830) and Ceratitis capitata (Wiedemann, 1824) and its relation with the pericarp of citrus fruits. We evaluated the relationship between depth of oviposition of A. fraterculus and C. capitata and epicarp thickness of orange [Citrus sinensis (L.) Osbeck)] 'Navelina' and tangerine [C. reticulata (L.)] 'Clemenules' and the influence of fruit mesocarp of tangerine 'Clemenules' on oviposition of these species. The study was conducted under controlled conditions of temperature (25 ± 2 °C), relative humidity (70 ± 10% RH) and photophase (12 h). A. fraterculus and C. capitata laid their eggs in the flavedo region of orange 'Navelina' and between the albedo and flavedo of tangerine 'Clemenules'. When fruits with mesocarp exposed were offered, there was no oviposition by both fruit fly species. The results show that epicarp thickness of citrus fruits did not influence oviposition of A. fraterculus and C. capitata as oviposition did not occur only in the presence of the mesocarp, suggesting that other factors are involved in oviposition of these species.Keywords: Anastrepha fraterculus, Ceratitis capitata, citrus peel structure, epicarp, mesocarp.Oviposição de moscas-das-frutas (Diptera: Tephritidae) e sua relação com o pericarpo de frutos cítricos ResumoAs moscas-das-frutas (Diptera: Tephritidae) representam um risco à fruticultura mundial, especialmente na cultura dos citros, entretanto estudos biológicos demonstram que as moscas-das-frutas não estão perfeitamente adaptadas à estes hospedeiros. Este estudo investigou a oviposição de Anastrepha fraterculus (Wiedemann, 1830) e Ceratitis capitata (Wiedemann, 1824) e sua relação com o pericarpo de frutos cítricos. Foi avaliada a relação entre a profundidade de oviposição de A. fraterculus e de C. capitata e a espessura do epicarpo dos frutos de laranjeira [Citrus sinensis (L.) Osbeck)] 'Navelina' e tangerineira [C. reticulata (L.)] 'Clemenules' e a influência do mesocarpo de frutos de tangerineira 'Clemenules' na oviposição destas espécies. O estudo foi conduzido em condições controladas de temperatura (25 ± 2 °C), umidade relativa (70 ± 10%) e fotofase (12 horas). A. fraterculus e C. capitata depositaram ovos no flavedo de frutos de laranjeira 'Navelina' e entre o flavedo e o albedo de frutos de tangerineira 'Clemenules'. Quando oferecido frutos com mesocarpo exposto, não houve oviposição por ambas as espécies de mosca. Os resultados demonstram que a espessura do epicarpo de frutos cítricos não influenciou a oviposição de A. fraterculus e de C. capitata, a qual não ocorreu na presença apenas do mesocarpo, sugerindo que outros fatores estão envolvidos na oviposição por estas espécies.Palavras-chave: Anastrepha fraterculus, Ceratitis capitata, estrutura da casca de citros, epicarpo, mesocarpo.
