  abstract = {{W}ing geometric morphometry of {T}riatoma infestans ({K}lug) ({H}emiptera: {R}eduviidae) populations in northwestern {A}rgentina showed that individual collection sites represent the discrete unit where metric differentiation took place. {H}ere we {S}tudied temporal variations in wing size and shape of {T}. infestans {P}opulations from defined capture sites on three occasions between 2000 and 2003. {B}ugs collected front domiciles and/or storerooms had significantly larger right-wing centroid size than bugs collected at goat and/or pig corrals by the end of summer 2000 for both sexes. {C}onversely, male bugs collected front domiciles and/or storerooms had significantly smaller centroid size than bugs collected from pig corrals in spring 2002. {T}he inversion in wing centroid size between seasons was consistent between sexes. {W}ing shape analysis from the south-central extreme of the {S}tudy village showed divergence between collection dates for both sexes. {W}ing shape divergence was highly significant between male bugs collected by the end of summer 2000 and those collected in spring 2002 and by the end of summer 2003. {F}or females, wing shape divergence was marginally significant between the end {O}f {S}ummer 2000 and spring 2002, and significant between spring 2002 and the end of summer 2003. {U}nlike season-related variations in wing centroid size, shape differentiation wits related to the time period elapsed between sample collections and {S}uggested genetic influences acting on shape. {S}imultaneous consideration of wing size and shape provided complementary information on the direction and timing of bug dispersal. {M}orphological studies may allow determining the degree of relatedness of different bug populations and to associate morphological heterogeneity with temporal patterns of reinfestation.},
