title: [The developmental cycle of Rhodnius nasutus Stal, 1859 studied in the laboratory].
abstract: The biological cycle of Rhodnius nasutus was studied from november 1985 to September 1986 under laboratory conditions. The temperature ranged from 28.0 +/- 2 degrees C to 22.0 +/- 2 degrees C and 59.2 to 70.4% of humidity. Chickens were used as a blood meal source. The complete biological cycle was achieved with an average of 209.4 days of the 16 remaining insects from initial colony of the 30 Katomines. The average incubation period lasted 11.1 days and those for the following nymphal stages were: 17.6 days for the first; 16.1 days for the second; 30.1 days for the third; 71.2 days for the fourth and 79.9 days for the fifth nymphal stage.
