title: [Triatoma tibiamaculata (Pinto, 1926): life table for nymphs, duration of adult forms and oviposition of females].
abstract: Under laboratory conditions, the authors analyzed the survival rate of nymphs, the minimum and maximum duration of each stage, the length of life of the winged forms and oviposition of the females. Two groups of 100 eggs each were monitored. In batch A, the specimens were reared in a single glass receptacle. In batch B, the specimens were kept apart, one by one, and when they reached the winged stage, they formed twenty couples, which made it possible to watch over the oviposition of the females and the length of life of each specimen. The egg eclosion rate was 96%; the proportion still alive at the end of the nymph phase was 69.5% in batch A and 78.4% in batch B. The most frequent length of time observed between oviposition and eclosion of first-stage nymphs was 28 days. The nymph phase lasted four to eight months and the adult phase five months. The mean total oviposition in batch B was 181.6 eggs per female.
