  abstract = {{BACKGROUND}: {I}nsecticide resistance management in {B}emisia tabaci is one of the main issues facing agricultural production today. {A}n extensive survey was undertaken in five {M}editerranean countries to examine the resistance status of {M}ed {B}. tabaci species in its range of geographic origin and the relationship between population genetic structure and the distribution of resistance genes. {T}he investigation combined molecular diagnostic tests, sequence and microsatellite polymorphism studies and monitoring of endosymbionts. {RESULTS}: {H}igh frequencies of pyrethroid ({L}925{I} and {T}929{V}, {VGSC} gene) and organophosphate ({F}331{W}, ace1 gene) resistance mutations were found in {F}rance, {S}pain and {G}reece, but not in {M}orocco or {T}unisia. {S}equence analyses of the {COI} gene delineated two closely related mitochondrial groups ({Q}1 and {Q}2), which were found either sympatrically ({S}pain) or separately ({F}rance). {O}nly {Q}1 was observed in {G}reece, {M}orocco and {T}unisia. {B}ayesian analyses based on microsatellite loci revealed three geographically delineated genetic groups ({F}rance, {S}pain, {M}orocco/{G}reece/{T}unisia) and high levels of genetic differentiation even between neighbouring samples. {E}vidence was also found for hybridisation and asymmetrical gene flow between {Q}1 and {Q}2. {CONCLUSIONS}: {M}ed {B}. tabaci is more diverse and structured than reported so far. {O}n a large geographic scale, resistance is affected by population genetic structure, whereas on a local scale, agricultural practices appear to play a major role.},
