Development of genital plates in nymphs of Triatoma pallidipennis, Stål 1872, (Hemiptera: Reduviidae) and its application as sexing method.

Biology of Triatoma pallidipennis stal 1945 (Hemiptera: Reduviidae:Triatominae) under laboratory conditions.

Aspects related to hatching, life time, mortality, feeding behaviour and fecundity for each stage of Triatoma pallidipennis life-cycle were evaluated. The hatching rate observed for 200 eggs was 60% and the average time of hatching was 18 days. Eighty nymphs (N) (40%) completed the cycle and the average time from NI to adult was 168. 7+/-11.7days. The average span in days for each stage was 18....

Feeding and defecation patterns of nymphs of Triatoma rubrofasciata (De Geer, 1773) (Hemiptera: Reduviidae), and its potential role as vector for Trypanosoma cruzi.

Preliminary results of random amplification of polymorphic DNA among Triatominae of the phyllosoma complex (Hemiptera, Reduviidae).

In Mexico, Triatoma longipennis (Usinger), Triatoma picturata (Usinger), and Triatoma pallidipennis (Stal), primary Chagas disease vector species of the phyllosoma complex, were analyzed by randomly amplified polymorphic DNA (RAPD). Sixteen decametric primers resolved individual profiles not identical, but partially discriminative between species. Analysis based on pairwise presence/absence com...

Description of the nymphs of Triatoma pintodiasi Jurberg, Cunha & Rocha, 2013 (Hemiptera: Reduviidae: Triatominae).

Triatoma pintodiasi Jurberg, Cunha & Rocha, 2013 has been recently described based on material collected on Rio Grande do Sul State, Brazil. Nymphs of this species were unknown and their description might contribute for studies concerning the taxonomy, phylogeny, and evolution of the genus Triatoma. Such description is herein presented, along with comparison with other species of the rubrovaria...

Presence of triatominae (Hemiptera, Reduviidae) and risk of transmission of Chagas disease in Colima, México.

With the purpose of evaluating the risk of transmission of the Chagas disease in the State of Colima, México, an entomological survey was performed to obtain triatominae and the rate of infection by Trypanosoma cruzi determined by examination of its dejections. Two hundred eighteen houses located in 16 villages were sampled. In each house the intradomestic and peridomestic habitats were examine...
