conditional embryonic lethality to improve the sterile insect technique in Ceratitis capitata diptera tephritidae
BMC Biology, 2009Co-Authors: Marc F Schetelig, Carlos E Caceres, Antigone Zacharopoulou, Gerald Franz, Ernst A. WimmerAbstract:Background The sterile insect technique (SIT) is an environment-friendly method used in area-wide pest management of the Mediterranean fruit fly Ceratitis capitata (Wiedemann; Diptera: Tephritidae). Ionizing radiation used to generate reproductive sterility in the mass-reared populations before release leads to reduction of competitiveness.

Cytogenetic analysis of chromosome 5 from the Mediterranean fruit fly, Ceratitis capitata.
Chromosoma, 1994Co-Authors: Philippe Kerremans, Gerald FranzAbstract:A cytogenetic map of chromosome 5 from the Mediterranean fruit fly, Ceratitis capitata, was constructed. Six mutations were located by translocation, transposition or deletion mapping. This knowledge allowed alignment and orientation of the existing linkage map with the polytene chromosomes. In addition, mapping of mutations used as selectable markers in genetic sex-separation strains is an essential prerequisite for the improvement of genetic stability during mass-rearing.

The ceratotoxin gene family in the medfly Ceratitis capitata and the Natal fruit fly Ceratitis rosa (Diptera: Tephritidae).
Heredity, 2003Co-Authors: Marco Rosetto, Silvia Ciolfi, Tiziana De Filippis, Daniela Marchini, Francesco Frati, Serge Quilici, Romano DallaiAbstract:The ceratotoxin gene family in the medfly Ceratitis capitata and the Natal fruit fly Ceratitis rosa (Diptera: Tephritidae)

Bacteria associated with the oesophageal bulb of the medfly Ceratitis capitata (Diptera: Tephritidae)
Current Microbiology, 2002Co-Authors: Daniela Marchini, Marco Rosetto, Romano Dallai, Laura MarriAbstract:Extracellular Gram negative bacteria were found to be commonly associated to the oesophageal bulb of Ceratitis capitata with Klebsiella oxytoca and Enterobacter agglomerans as the most common species. All the isolates tested in vitro, except one, were sensitive to the antibacterial material present on the medfly laid egg surface.

Ceratotoxins: female-specific X-linked genes from the medfly, Ceratitis capitata.
Genome, 2000Co-Authors: Marco Rosetto, Daniela Marchini, A. Zacharopoulou, T. De Filippis, Mauro Mandrioli, P. Gourzi, Andrea G. O. Manetti, Romano DallaiAbstract:In this paper, we report the chromosomal localization of ceratotoxins, a gene family encoding antibacterial female-specific peptides from the mediterranean fruit fly Ceratitis capitata. The analysis of both polytene and mitotic chromosomes by in situ hybridization shows that ceratotoxins are the first case of female-specific X-linked genes from the medfly C. capitata. Southern blot analysis reveals that the ceratotoxin gene family is not specifically amplified in the female reproductive accessory glands of C. capitata.Key words: ceratotoxins, female-specific genes, Ceratitis capitata, X chromosome, in situ hybridization.

Primordial germ cell migration in the Ceratitis capitata embryo.
Tissue & cell, 1996Co-Authors: Maria Giovanna Riparbelli, Giuliano Callaini, Romano DallaiAbstract:Abstract In this study we followed the behavior of germ cell precursors in the early embryo of the dipteran Ceratitis capitata using conventional fluorescence, laser scanning confocal and transmission electron microscopies. During cellularization the pole cells formed a cluster which lodged in a roundish break in the blastoderm at the posterior pole of the embryo. When gastrulation began, the pole cells shifted dorsally and during elongation of the germ band moved into the posterior midgut primordium. Pole cell morphology suggested that these cells were motile until the early stages of development.

The cytoskeleton of the ventral nephrocytes of Ceratitis capitata larva
Cell & Tissue Research, 1994Co-Authors: Romano Dallai, Maria Giovanna Riparbelli, Giuliano CallainiAbstract:Nephrocytes are cells involved in the regulation of the composition of the hemolymph and are characterized by peripheral finger-like projections delimiting a labyrinthine channel system. We have combined structural and immunological methods to examine the spatial distribution of microtubules and microfilaments in disseminated nephrocytes of Ceratitis capitata larva; the nephrocytes are scattered among the fat-body cells, close to the salivary glands. Actin filaments are localized in two discrete peripheral domains and microtubules are mostly concentrated in the cortical region. We discuss the possibility that these cytoskeletal elements, localized in the finger-like processes of the plasma membrane, are involved in maintaining the spatial architecture of the cell periphery and in modifying the junctional complexes that represent the entrance to the labyrinthine channel system.
