[Observations on oviposition, hatching and the life span of Triatoma matogrossensis Leite & Barbosa, 1953 (Hemiptera, Reduviidae) as a function of their feeding on pigeons and rabbits].
A laboratory study was carried out concerning the influence of two kinds of blood-meal on egg laying, egg hatching and life span of Triatoma matogrossensis. 68 couples in 4 different groups with 20, 12, 20 and 16 individuals of each sex per group were formed. Maintained under laboratory conditions groups A1 and A2 were fed on pigeons and groups C1 and C2 were fed on rabbits. In relation to egg laying the best results were found in group A1. No differences on egg hatching were found between the groups fed on rabbits and those fed on pigeons. Concerning the life span, no differences between males and females in the 4 groups were observed but group A1 presented the longest life span and group C2 the shortest.
