Estudou-se a influência da temperatura no ciclo evolutivo de Triatoma maculata (Erichson) (Hemiptera, Reduviidae), tendo em vista uma criação em grande escala, em laboratório, para serem testados no xenodiagnóstico e, ainda, fornecer informações que subsidiem investigações sobre esta espécie. Apresentam-se os resultados do ciclo evolutivo obtidos a 25±0,5°C e 30°C±1,0°C , com umidade relativa de 70+5% e fotoperíodo de 12 horas, que foram de 223,5 e 222,3 dias, para machos e fêmeas, respectivamente, a 24°C e 30°C, a duração média foi de 168,7 e 167,2 dias, respectivamente, para machos e fêmeas.
Abstract
The influence of temperature on the biology of Triatoma maculata (Erichson) (Hemiptera, Reduviidae), was studied in order to obtain a larger number of Triatominae reared in laboratory. to use in xenodignosis. The experiments were performed in two climatized chambers at 25±0.5°C and 30°C±1.0°C , 70+5% of relative humidity and fotoperiod of 12 hours. The mean duration of the evolutive cycle for males and females was 223.5 and 222.3 days, at 25°C, and 168.7, and 167.2 days, at 30°C.
Résumé
Linfluence de la temperature dans la biologie de Triatoma maculata (Erichson) (Hemiptera, Reduviidae), a été étudié. pour obtenir un grand numéro de Triatominae, élevé on laboratoire et utilizé le xenodiagnostique. Les épreuves ont étés faites dans deux chambres climatiques à 25±0,5°C et 30°C±1,0°C humidité relatif était 70±5% et le photopériode de 12 heurs. En moyenne, la durée du cycle évolutif a été pour les mâles et les femelles de 223,5 et de 222,3 jours à 25°C. et 168,7 et de 167,2 jours, à 30°C.
