Abstract: The presence of Triatoma infestans in habitats treated with insecticides constitutes a frequent problem in endemic areas. Basing our study on the hypothesis that descendants of a residual population should be more similar to the pre-treatment population than to any other, we compared the indications of two quantitative morphological approaches. This study seeks to find the origin of 247 T. infestans from three populations found in two chicken coops and a goat corral after treatment with insecticides. The resul… Show more

“…The trial also provided updated information on the occurrence of house infestation with T. infestans and other triatomine species in northern Mendoza province, documenting high bug abundance in domestic and peridomestic sites. Peridomestic (re)infestation by T. infestans has been documented elsewhere in the Gran Chaco ecoregion 19,20,21,22,23,24 but not in Mendoza province.…”

“…Schofi eld et al (84) collected very few adult M. spinolai after six years of sampling. Moreover, in studies of reinfestant Triatominae, low number of insects collected after an insecticide spray can also raise doubts about the technique used (27) (85) . The results of these studies can provide evidence for further long-term studies, which might increase the number of insects collected and enhance the power of statistical tests.…”

“…Pyrethroid‐based suspension concentrate formulations applied using traditional spraying techniques have been reported as less efficacious in peridomestic habitats in which exposure to the environmental conditions of peridomestic structures decreases the residual lethality of the insecticide, favouring the survival of residual T. infestans populations after the application of insecticide (Gürtler et al ., ; Cecere et al ., ). Active or passive dispersal from these residual foci may represent the most probable mechanisms of the subsequent domiciliary re‐infestation of rural settlements that have been treated with pyrethroid insecticides (Schofield, ; Abrahan et al ., ; Hernández et al ., ).…”
