“…Some, such as P. megistus, are important vectors of Chagas disease due to their close association with humans. Others, such as P. chinai, P. geniculatus, P. herreri and P. rufotuberculatus are considered secondary vectors because of their increasing ability to invade and colonise domestic habitats (Lent and Wygodzinsky, 1979;Calderón et al, 1985;Noireau et al, 1994;Valente, 1999;Carcavallo et al, 1999;Wolff and Castillo, 2000;Abad-Franch et al, 2001).…”
