Abstract
In a survey of wild populations of Triatoma infestans (Klug) in Argent ina, 10% were infected with Triatoma virus (TrV). The virus also was d etected in a laboratory colony 18 mo after being established, with inf ection rates up to 100%. Mortality rate was 97.6% in nymphs and the mo lting process was inhibited, thereby increasing development time. Beca use the virus was detected in colony nymphs, TrV may be transmitted ve rtically. However, the higher infection rate in the colony compared wi th natural populations also indicates other route(s) of transmission.
