Altered GPI modification of insect AChE improves tolerance to organophosphate insecticides
(2011)The olive fruit fly Bactrocera oleae is the most destructive and intractable pest of olives. The management of B. oleae has been based on the use of organophosphate (OP) insecticides, a practice that induced resistance. ... -
Ancestral populations perform better in a novel environment: domestication of Mediterranean fruit fly populations from five global regions
(2011)Geographically isolated populations of a species may differ in several aspects of life history, morphology, behaviour and genetic structure as a result of adaptation in ecologically diverse habitats. We used a global ... -
Anopheles gambiae odorant binding protein crystal complex with the synthetic repellent DEET: implications for structure-based design of novel mosquito repellents
(2012)Insect odorant binding proteins (OBPs) are the first components of the olfactory system to encounter and bind attractant and repellent odors emanating from various sources for presentation to olfactory receptors, which ... -
Dual reproductive cost of aging in male medflies: Dramatic decrease in mating competitiveness and gradual reduction in mating performance
(2011)Although age-based effects on the reproductive success of males have been reported in several animal taxa the cost of aging on male mating success in lekking species has not been fully explored. We used the Mediterranean ... -
Genetic and cytogenetic analysis of the fruit fly Rhagoletis cerasi (Diptera : Tephritidae)
(2008)The European cherry fruit fly, Rhagoletis cerasi, is a major agricultural pest for which biological, genetic, and cytogenetic information is limited. We report here a cytogenetic analysis of 4 natural Greek populations of ... -
Genome size estimation with quantitative real-time PCR in two Tephritidae species: Ceratitis capitata and Bactrocera oleae
(2012)The medfly Ceratitis capitata and the olive fruit fly Bactrocera oleae belong to the Tephritidae family of Diptera, a family whose members cause severe damages in agriculture worldwide. For such insect pests, the utmost ... -
Geographical variation in adult life-history traits of the European cherry fruit fly, Rhagoletis cerasi (Diptera: Tephritidae)
(2012)To understand the evolution of local adaptation, the interplay between natural selection and gene flow should be considered. Rhagoletis cerasi L. (Diptera: Tephritidae) is a patchily distributed, stenophagous species of ... -
Isolation and characterization of microsatellite markers from the Mediterranean fruit fly, Ceratitis capitata: cross-species amplification in other Tephritidae species reveals a varying degree of transferability
(2009)The Mediterranean fruit fly, Ceratitis capitata, is a pest of major economic importance and has become a model for the development of SIT control programs for insect pests. Significant information has been accumulated on ... -
Isolation and characterization of microsatellite markers from the olive fly, Bactrocera oleae, and their cross-species amplification in the Tephritidae family
(2008)Background: The Tephritidae family of insects includes the most important agricultural pests of fruits and vegetables, belonging mainly to four genera (Bactrocera, Ceratitis, Anastrepha and Rhagoletis). The olive fruit ... -
Isolation, annotation and applications of expressed sequence tags from the olive fly, Bactrocera oleae
(2011)The olive fruit fly, Bactrocera oleae, is the major pest of the olive tree. Despite its importance, very little genetic and molecular knowledge is available. The present study is a first attempt to identify and characterize ... -
Microsatellite and Wolbachia analysis in Rhagoletis cerasi natural populations: population structuring and multiple infections
(2014)Rhagoletis cerasi (Diptera: Tephritidae) is a major pest of sweet and sour cherries in Europe and parts of Asia. Despite its economic significance, there is a lack of studies on the genetic structure of R.cerasi populations. ... -
The molecular biology of the olive fly comes of age
(2014)Background: Olive cultivation blends with the history of the Mediterranean countries since ancient times. Even today, activities around the olive tree constitute major engagements of several people in the countryside of ... -
Molecular Characterization and Chromosomal Distribution of a Species-Specific Transcribed Centromeric Satellite Repeat from the Olive Fruit Fly, Bactrocera oleae
(2013)Satellite repetitive sequences that accumulate in the heterochromatin consist a large fraction of a genome and due to their properties are suggested to be implicated in centromere function. Current knowledge of heterochromatic ... -
Olive fly transcriptomics analysis implicates energy metabolism genes in spinosad resistance
(2014)Background: The olive fly, Bactrocera oleae, is the most devastating pest of cultivated olives. Its control has been traditionally based on insecticides, mainly organophosphates and pyrethroids. In recent years, the ... -
Polygyny in the olive fly-effects on male and female fitness
(2015)Polygynous males must balance their limited ejaculate resources between current copulations, with putative future ones. Working on olive flies (Bactrocera oleae), our objectives were to determine (a) how males budget sperm ...
