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

Wolbachia in guilds of Anastrepha fruit flies (Tephritidae) and parasitoid wasps (Braconidae)
Abstract The endosymbiont Wolbachia is efficiently transmitted from females to their progenies, but horizontal transmission between different taxa is also known to occur. Aiming to determine if… Expand

A gene that modifies the sex ratio in a bisexual strain of Sciara ocellaris
SummaryThe influence of an X-linked recessive mutation, sepia, on the sex determination of a bisexual strain of Sciara ocellaris was studied. It induces an alteration in the sex ratio, especially in… Expand

Changes in chromosomes and in development of cells of Sciara ocellaris induced by microsporidian infections
Two species of microsporidia distinguished by the shape of their spores were found to infect cells of various tissues of Sciara ocellaris. Although the infection affects profoundly the development of… Expand

Facultative polar extrusion of yolk masses and of hatching at the posterior egg pole in tephritid fruit flies (Diptera)
The eggs of Anastrepha fracterculus, A. sororcula, A. obliqua, A. serpentina and of Ceratitis capitata (Diptera : Tephritidae) show considerable morphological differences. Differences were also… Expand

Nuclear division and migration during early embryogenesis of Bradysia tritici coquillet (syn. Sciara ocellaris) (diptera : Sciaridae)
Abstract Nuclear division and migration of cleavage nuclei in the embryos of Bradysia tritici (Diptera : Sciaridae) have been studied by light microscopy and nuclear staining. There are 8 cleavage… Expand

Variations in the sensitivity of different primers for detecting Wolbachia in Anastrepha (diptera: tephritidae)
Wolbachia are endosymbiont bacteria of the family Rickettsiacea that are widespread in invertebrates and occur between 20% and 60% of Neotropical insects. These bacteria are responsible for… Expand

Double abdomen induction by UV in Bradysia tritici (syn. Sciara ocellaris, Sciaridae): sensitive stages and conditions for photoreversal
SummaryThe pattern anomaly double abdomen was induced in embryos of Bradysia tritici (syn. Sciara ocellaris) by irradiation of the anterior egg pole with far UV (254 or 285 nm) using low UV fluences.… Expand
