English abstract Xenodiagnoses were performed every 3 hours using 10 Triatoma infestans 3rd instar for 24 to 72 hours, in 18 chronic chagasics with positive serology and/or xenodiagnosis. There was no statistically significant difference in the positivity of assays performed during the day (9:00 to 18:00h) compared to those performed at night (21:00 to 6:00h), (chi² = 0.1526 p = 0.696). Xenodiagnosis was performed in ten of the patients for 13 successive days but there was no periodicity detected in the positive assays
Portuguese abstract Realizamos xenodiagnósticos de 3 em 3 horas com 10 ninfas do 3° estágio de Triatoma infestans por um período de 24 a 72 horas, em 18 chagásicos crônicos que tinham sorologia e/ou xenodiagnóstico positivos. Não houve diferença estatisticamente significante na positividade entre os testes realizados durante o dia (9:00 às 18:00h) e à noite (21:00 às 6:00h), (chi² = 0,1526 p = 0,696). Dez dos pacientes fizeram também xenodiagnósticos diários, durante 13 dias sucessivos, não havendo periodicidade dos testes positivos
