Resumen
Rhodnius ecuadoriensis infests peridomiciles and colonises houses in rural southern Ecuador. Six out of 84
dwellings (7%) surveyed in a rural village were infested (78 bugs/infested domicile; 279 bugs were collected in a
single dwelling). Precipitin tests revealed R. ecuadoriensis fed on birds (65%), rodents (31%), marsupials (8%),
and humans (15%) – mixed bloodmeals detected in 37.5% of individual samples. Trypanosoma cruzi from opossums
and rodents may thus be introduced into the domestic cycle. Wasp parasitoidism was detected in 6.5% of 995 R.ecuadoriensis eggs (only in peridomestic habitats). Control strategies should integrate insecticide spraying (indoors and peridomestic), better management of poultry, and housing improvements. A possible inefficacy of Malathion is reported.
