  abstract = {{I}dentifying the origins of insect vectors collected after community-wide residual insecticide applications is a relevant challenge in the {G}ran {C}haco region where the main vector of {C}hagas disease {T}riatoma infestans usually reinfests human dwellings. {W}ing geometric morphometry was used to compare the right wings of 63 males and 54 females collected at 4 months post-spraying ({MPS}) with those from 165 males and 111 females collected before full-coverage spraying with pyrethroids in a well-defined rural area in {N}ortheastern {A}rgentina. {M}ale and female wing centroid size resulted significantly larger at 4 {MPS} than before interventions, but no significant changes in shape were detected. {M}etric disparity (variance of shape) varied significantly in males but not in females. {U}sing shape variables, a relatively large fraction of post-spraying males (70%) and females (54%) could not be differentiated from those collected at the same source house or at the nearest infested house before interventions. {B}ugs collected at 4 and 8 {MPS} in a persistently infested house were mainly assigned to the source house. {T}hese results support the hypothesis of persistent bug populations that survived the insecticide application at local spatial scales, and are consistent with the occurrence of vector control failures most likely related to moderate pyrethroid resistance. {W}ing geometric morphometry is a useful tool for identifying sources of reinfestation, but it is limited by the spatial structure found in the reference populations. {C}ombined with field and genetic data, this approach may contribute to the understanding of the reinfestation process and improvement of vector control strategies.},
