ROCHA, Dayse da Silva; GALVAO, Cleber  and  JURBERG, José. Biology of Rhodnius pictipes Stal, 1872 under laboratory conditions (Hemiptera, Reduviidae, Triatominae). Mem. Inst. Oswaldo Cruz [online]. 1994, vol.89, n.2, pp. 265-270. ISSN 0074-0276.  http://dx.doi.org/10.1590/S0074-02761994000200028.

Rhodnius pictipes Stal, 1872 is a silvatic species with a widespread distribution in South America, found in nine Brazilian states, naturally infected by Trypanosoma cruzi and T. rangeli. The individual rearing of this species under laboratory conditions, allowed the following biological aspects to be observed: incubation time, search for first meal after eclosion or moult, time - lapse between presentation of the blood meal and the beginning of feeding, duration of blood meal, time and place of defecation, number of blood meals, duration of each instar and adult longevity, and time required from egg to adult.

Keywords : Rhodnius pictipes; evolutive cycle; laboratory conditions; Triatominae; life cycle.
