  abstract = {{T}riatoma guasayana ({W}ygodzinsky & {A}balos) is a peridomestic triatomine with epidemiological importance in {B}olivia, that may play an important role in the transmission of {T}rypanosoma cruzi ({C}hagas). {I}n this study, two parameters of vectorial capacity were evaluated: the interval of feeding-defecation time and metacyclogenesis, in adult males and females and nymphal instars {II} to {V} of {T}. guasayana with comparisons with {T}riatoma infestans ({K}lug) and {T}. sordida ({S}tal). {T}he results showed a close relationship between ingestion of blood and beginning of defecation. {V}alues were negative in {T}. infestans, and {T}. sordida for instars {II}, {III}, {IV}, and {V} and also males and females but were positive in female {T}. sordida. {T}riatoma guasayana showed only negative values for instar {II}. {A}dults and nymphs began defecation as soon as they had finished feeding and required an average of 29.8 min. {T}he analysis of metacyclogenesis showed that {T}. guasayana was superior to {T}. infestans and {T}. sordida. {H}owever, the vectorial effectiveness of {T}. guasayana was significantly affected regarding the percentage of metacyclic trypomastigotes during instars {III} to {V} and showed a progressive increase. {F}emales had higher proportions despite their ingestion being half that of {T}. infestans. {T}he different instars of {T}. guasayana had a higher parasitic load than those of {T}. sordida and, although ingestion was 1/3 of that of female {T}. infestans, there was a progressive increase in metacyclic trypomastigotes in the different nymphal stages of {T}. guasayana that decreased in adults.},
