The Significance of Genetic Polymorphisms within and between Founder Populations of Ceratitis capitata (Wied.) from Argentina
BACKGROUND The Mediterranean fruit fly Ceratitis Capitata (DIPTERA: Tephritidae) is a major agricultural pest in Argentina. One main cause for the success of non-contaminant control programs based on genetic strategies is compatibility between natural and laboratory germplasms. A comprehensive characterization of the fruit fly based on genetic studies and compatibility analysis was undertaken o...
متن کاملA second superoxide dismutase gene in the medfly, Ceratitis capitata.
We report the first case of two Cu/Zn Sod genes (ccSod1 and ccSod2) that have been cloned and sequenced from an insect, the medfly, Ceratitis capitata. Biochemical evidence suggested the presence of two Sod genes in the medfly. The two genes are isolated using different molecular strategies: ccSod1 via cross-hybridization to a genomic library using a heterologous probe and ccSod2 from cDNA usin...
متن کاملBacteria–diet interactions affect longevity in the medfly – Ceratitis capitata
Symbiosis in fruit flies (Dipt.: Tephritidae), despite its long history of study, is still a relatively poorly understood aspect of the life history of these insect pests (reviewed by Drew and Lloyd 1991; Lauzon 2003). Many tephritid species are uniquely adapted for housing large quantities of bacteria in their digestive tract (the oesophageal bulb in adults and gastric caeca in larvae) and som...
متن کاملAllozymic variability in Spanish populations of Ceratitis capitata
– Introduction. The Tephritidae Ceratitis capitata is one of the most important agricultural pests in the world. Eradication programmes need as much genetic information as possible to be efficient. It is vital to know the genetic variation that exists in the areas thought to have been important in the expansion of the species, such as the Iberian Peninsula. The aim of this study was to determin...
متن کاملAdaptation to divergent larval diets in the medfly, Ceratitis capitata
Variation in diet can influence the timing of major life-history events and can drive population diversification and ultimately speciation. Proximate responses of life histories to diet have been well studied. However, there are scant experimental data on how organisms adapt to divergent diets over the longer term. We focused on this omission by testing the responses of a global pest, the Medit...
