Biology of Triatoma nitida usinger, 1939 under laboratory coditions.

In addition to variable rates of parasite infection among vectors, different rates of human infection are related with different vector species or populations, suggesting that

Mean time-lapse for beginning feeding was under 3 min for nymphal stages, in both cohorts and for adults of the cohort fed on rabbits (Table III) with no significant (P >

nitida appears to have a low importance as Chagas disease vector in Guatemala, as indicated by its scarce presence in the domestic habitats and defecation patterns.. However,

In Mexico, Triatoma longipennis (Usinger), Triatoma picturata (Usinger), and Triatoma pallidipennis (Stal), primary Chagas disease vector species of the phyllosoma complex,

Meccus longipennis Usinger, is one of the most important vectors of Chagas disease in Mexico, because of the current presence of its populations in both domestic and wild ecotopes

Mortality rates were significantly (p < 0.05) higher for 1st instar nymphs than for the rest of studied instars in each of the three studied cohorts independent of tem-

The values of biological parameters related to hatching, lifespan, the number of blood meals between moults, mor- tality, time lapse before the beginning of feeding, feeding time

The life cycle of Triatoma klugi Carcavallo, Jurberg, Lent & Galvão 2001 was compared under laboratory conditions using two groups of the F1 generation obtained
