摘　　要：Objective:To investigate the bioecological relationship between Chagas disease peridomestic vectors and reptiles as source of feeding.Methods:In a three-story building,triatomines were captured by direct search and electric vacuum cleaner search in and outside the building.Then,age structure of the captured Triatoma maculata(T.maculata) were identified and recorded.Reptiles living in sympatric with the triatomines were also searched.Results:T.maculata were found living sympatric with geckos(Thecadactylus rapicauda) and they bit residents of the apartment building in study.A total of 1 448 individuals of T.maculata were captured within three days,of which 74.2%(1 074 eggs) were eggs,21.5%were nymphs at different stages,and 4.3%were adults.Conclusions:The association of T.maculata and T.rapicauda is an effective strategy of colonizing dwellings located in the vicinity of the habitat where both species are present;and therefore,could have implications of high importance in the intradomiciliary transmission of Chagas disease.Objective:To investigate the bioecological relationship between Chagas disease peridomestic vectors and reptiles as source of feeding.Methods:In a three-story building,triatomines were captured by direct search and electric vacuum cleaner search in and outside the building.Then,age structure of the captured Triatoma maculata(T.maculata) were identified and recorded.Reptiles living in sympatric with the triatomines were also searched.Results:T.maculata were found living sympatric with geckos(Thecadactylus rapicauda) and they bit residents of the apartment building in study.A total of 1 448 individuals of T.maculata were captured within three days,of which 74.2%(1 074 eggs) were eggs,21.5%were nymphs at different stages,and 4.3%were adults.Conclusions:The association of T.maculata and T.rapicauda is an effective strategy of colonizing dwellings located in the vicinity of the habitat where both species are present;and therefore,could have implications of high importance in the intradomiciliary transmission of Chagas disease.
