“…At the low-elevation site, n ϭ 521 and 629 matings for wild and tsl males, respectively. idence of limited genetic (Gasparich et al 1997) and behavioral (Cayol 2000) divergence among wild medßy populations clearly supports the "one strain for all programs" view. However, the apparent absence of premating isolation barriers among wild populations should not be misconstrued as evidence that males of a generic, mass-reared strain will compete uniformly well in all regions in which they are released.…”

The release of sterile males is a key component of an areawide program to eradicate the Mediterranean fruit fly, Ceratitis capitata (Wiedemann), from Guatemala and southern Mexico. The objective of our study was to assess the effects of adult diet, exposure to ginger root oil (Zingiber officinale Roscoe), and elevation on the mating competitiveness of the sterile males used in an areawide program. Sterile males were maintained on a protein-sugar (protein-fed) or a sugar-only (protein-deprived) diet and were exposed (for 4 h 1 d before testing) or not exposed to ginger root oil. In field-cage trials conducted at a high (1,500 m) and low (700 m) site, we monitored the influence of these treatments on the mating success of sterile males in competition with wild males (reared exclusively on the protein-sugar diet and without ginger root oil exposure) for wild females. Elevation and ginger root oil exposure had significant effects, with sterile males having higher mating success at the low-elevation site and ginger root oil-exposed males having greater success than ginger root oil-deprived males at both sites. Diet did not have a significant overall effect, and its influence varied with elevation (dietary protein seemed to provide an advantage at the high-elevation site but not at the low-elevation site). Possible implications of these findings for eradication programs against the Mediterranean fruit fly are discussed.

“…Th e haplotype code is based on the presence (A) or absence (B) of the restriction site of these enzymes (Sheppard et al 1992). For Instance, a study conducted by Gasparich et al (1997), revealed the presence of one haplotype in Hawaii (BBB), seven haplotypes in Subsaharan Africa (AAA, AAB, BAB, ABA, BBA, BAA and BBB) and two haplotypes in the Mediterranean area (AAA and AAB). Recently, Barr (2009) examined the medfl y pathway using a revised protocol of the previous above mentioned study and reported two more haplotypes in the Mediterranean basin (BBB and BAA).…”

“…Th is consistent with the idea that the Tunisian populations, which are "ancient" by medfl y standards , are expected to be more diverse than populations recently established (Reyes and Ochando 2004). Previous studies had shown that the fi rst major expansion of this pest into non native areas included countries of the Mediterranean basin ), but quantifi cation of the level of variability in these populations had remained elusive when populations, such as those from Tunisia, proved to be diffi cult to analysis using the PCR-RFLP approach (Gasparich et al 1997). As described previously, one of the limitations of any PCR-FRLP approach is the inability to detect novel variants.…”

Abstract. The Mediterranean fruit fl y (medfl y) Ceratitis capitata (Diptera: Tephritidae) is known to be one of the most destructive and economically important agricultural pests worldwide. Several previous research projects have investigated the genetic makeup of regional populations of this pest and the relationships of populations from different areas of the world, including countries from the Mediterranean region. However, previously, little information has been reported on populations from Tunisia, despite the fact that this pest occurs in several agriculturally sensitive areas of this country. In order to study the genetic diversity of medfl y populations within Tunisia, specimens were collected from the Coastal, Northern, Central and Southern regions of the country. Results using mitochondrial ND5 sequences show the presence of distinct haplotypes. This data used to analyze the levels of genetic variability within and between populations from Tunisia as well as from other countries in the Mediterranean region (Morocco and Israel) and in the world (Seychelles and Hawaii). This study also leads to a better understanding of the origin of new infestations and the colonization processes involving this pest. Résumé. Diversité génétique des confi gurations mitochondrial ND5 chez les populations deCeratitis capitata (Diptera : Tephritidae) de Tunisie. La mouche méditerranéenne des fruits Ceratitis capitata (Wiedemann) (Diptera : Tephritidae) est l'un des ravageurs les plus importants en agriculture dans le monde. Plusieurs travaux de recherche ont étudié les caractéristiques génétiques de la cératite ainsi que les relations entre populations de ce ravageur provenant de différentes régions du globe y compris les pays appartenant au bassin méditerranéen. Cependant, très peu d'informations sont disponibles concernant les populations de cératite en Tunisie, malgré l'importance économique de ce ravageur dans des zones clés de production fruitière tunisiennes. Dans le but d'étudier la diversité génétique des populations de cératite en Tunisie, des spécimens ont été collectés du Cap Bon, Nord, Centre et sud de la Tunisie. Les résultats basés sur l'étude des séquences du gène mitochondrial ND5 révèlent la présence d'haplotypes distincts. Ces haplotypes ont permis d'analyser les niveaux de variabilité génétique entre les populations tunisiennes et les autres populations de cératite du bassin méditerranéen (Maroc et Israël) ainsi que des populations prélevées dans d'autres régions du monde (Iles Seychelles et Hawaï). Cette étude a permis également de mieux caractériser l'origine de nouvelles infestations ainsi que les processus de colonisation de ce ravageur.

“…The literature on intercontinental relationships is particularly abundant with respect to single species (e.g., Sperling and Harrison, 1994;McMichael and Hall, 1996;Gasparich et al, 1997), but apart from Drosophila (e.g., Powell, 1997;Barrio and Ayala, 1997), there have been comparatively few investigations of insects above the species level (e.g., Sperling and Harrison, 1994;McPheron and Han, 1997;Friedlander et al, 1998). This is not to imply that the fundamental processes are any different, but rather that events associated with the evolution of higher taxa are expected to have occurred at an earlier time, perhaps coinciding with major reconfigurations of land areas, caused by continental drift (Vermeij, 1991).…”
