Biology of Triatoma klugi Carcavallo, Jurberg, Lent & Galvão 2001 (Heteroptera: Reduviidae) under Laboratory Conditions: Effects of Distinct Blood Sources and Susceptibility to Trypanosoma cruzi and Trypanosoma rangeli

Spermatogenesis and nucleolar activity in Triatoma klugi (triatomine, Heteroptera)

“…Triatoma klugi specimens susceptible to different lineages of Trypanosoma cruzi showed an infection similar to that observed in Triatoma infestans (T. infestans) (Joukoski et al, 2000). Under laboratory conditions this species presented an infection rate for the T. cruzi lineages 60% higher than previously observed (Emmanuelle-Machado et al, 2002).…”

“…This structure resembles the nucleolar bodies present in triatomine spermatids. Triatoma klugi has been recently described by Carcavallo et al (2001) and it is morphologically related to T. oliveirai, justifying its inclusion in the oliveirai complex (Emmanuelle-Machado et al, 2002). The purpose of this paper was to describe the karyotype of male Triatoma klugi and to analyze the chromosomes meiotic behavior and nucleolar cycle during spermatogenesis.…”

Life cycle and vectorial competence of Triatoma williami (Galvão, Souza e Lima, 1965) under the influence of different blood meal sources

“…The cumulative mortality until the fifth nymphal instar of T. williami was higher in BIR group as was also shown by T. klugi (Emmanuelle-Machado et al, 2002), Rhodnius neglectus (Diotaiuti & Dias, 1987), T. brasiliensis, T.…”

Parâmetros populacionais para Triatoma sordida Stal, 1859, o vetor mais freqüente da doença de Chagas no Triângulo Mineiro (Heteroptera, Triatominae)

“…Rhodnius neglectus apresenta ciclo de vida mais curto quando se alimenta em mamíferos, quando comparado com fonte alimentar em aves 5 . Mudanças no ciclo de vida de Triatoma klugi, em função da fonte alimentar, também já foram relatadas-camundongos ou galinhas 7 ; assim como mudanças significativas para Meccus picturatus, quando alimentados com galinhas ou coelhos 10 . A taxa reprodutiva líquida, que é o número de fêmeas produzido por uma fêmea, apresentou valor de R 0 igual a 55 fêmeas/geração.…”
