  abstract = {{T}he whitefly {B}emisia tabaci is a species complex including at least 24 morphologically indistinguishable species among which the {M}editerranean ({M}ed) and {M}iddle {E}ast-{A}sia {M}inor {I} ({MEAMI}) species containing the biotypes commonly known as {Q} and {B}, respectively. {T}hese {B} and {Q} biotypes (hereafter referred to as {MEAMI} and {M}ed species) are the most invasive agricultural pests of the {B}. tabaci complex worldwide. {T}he spread of {MEAMI} and more recently of {M}ed species into regions already invaded by other {B}. tabaci populations has been frequently seen to lead to their displacement by {M}ed species. {I}n {T}unisia, in contrast to usual observations in the {M}editerranean basin, {M}ed and {MEAMI} species have been seen to co-occur in the main crop producing regions. {B}ased on fine population genetics and field spatial distribution analyses, we found that the co-existence of these two interacting species was based on habitat partitioning including spatial and host-plant partitioning. {A}lthough they co-occurred at larger spatial scales, they excluded one another at sample scale. {W}e observed neither spatial overlapping nor hybridization between {MEAMI} and {M}ed {B}. tabaci. {V}egetable crops were the main hosts for {MEAMI} specimens while 99.1% of the {B}. tabaci collected on the ornamental, {L}antana camara, were {M}ed specimens. {D}ifferent patterns of genetic diversity were observed between the two species, as well as among {M}ed specimens sampled on the ornamental versus vegetables, with the highest genetic diversity found in {M}ed {B}. tabaci sampled on {L}. camara. {T}hese findings lead us to focus our discussion on the role played by lantana, human pressure, and competition, in the spatial and genetic patterns observed in the whitefly {B}. tabaci.},
