Início da atividade de vôo em Triatoma infestans (Klug, 1834) e T. melanosoma Martínez, Olmedo & Carcavallo, 1987 (Hemiptera, Reduviidae) / Flight initiation in Triatoma infestans and T. melanosoma (Hemiptera, Reduviidae)

ABSTRACT

The flight initiation of T. infestans, the main vector of Chagas disease in the Southern Cone countries of Latin America, and of the closely-related species T. melanosoma was studied in laboratory. The results demonstrated that after the beginning of observations the peak of the flight activity was about 14 days after feeding in both species and it was usually more marked in the females than in the males, but there were no significant differences in the flight behaviour of the two species
