Resumo: | The behavior of Triatoma sordida maintained in stoves with relative atmospheric humidity of 60-70% and temperatures, respectively, of 25°C and 30°C was observed. The higher temperature caused a shortening of the growth phases. The growth of the fifth instar took longer in males than in females. The longevity of adult females was greater than that of males. With regard to ingested blood higher averages were observed at 25°C, except in the 5th instar, and the females had the highest averages in the 4th and 5th instars. With regard to the number of repasts, at 25°C the average was higher in the 1st, 2nd and 3rd instars; there was interaction of temperature and sex in the 4th instar and there was no significant difference in the 5th instar; the number of repasts of males was larger than that of females only in the 5th instar. The initial weight of triatomid bugs was greatest at 25°C in all the instars except the 1st; females at 25°C had greater weight than males in the 4th and 5th instars and at 30°C in the 5th instar only. Effects of temperature and sex in the starvation resistance of T. sordida were observed. The triatomid bugs were not manipulated or fed after the move to instar study. The average of starvation resistance measured in days was longer in all the instars of the growth cycle, but, in the adult phase, there was interaction of temperature and sex. The correlation between starvation resistance and the last weight of the immediately previous instar was the only one that was consistently positive, being significant in eight only of the twelve possible correlations. |

Foi observado o comportamento do Triatoma sordida, mantido em condições de laboratório em estufas com umidade relativa do ar de 60-70% e temperatura de 25°C e 30°C. A temperatura mais alta determinou um encurtamento da duração das fases de evolução. Os machos tiveram a duração do 5.° estádio maior do que a das fêmeas. A duração das fêmeas adultas foi maior do que a dos machos. Em relação ao sangue ingerido observaram-se médias maiores à temperatura de 25°C, exceto no 5.° estádio, bem como, nos 4.° e 5.° estádios, as fêmeas tiveram médias maiores. O número de respostas à temperatura de 25.°C foi maior nos 1.°, 2.° e 3.° estádios; no 4.° ocorreu interação temperatura-sexo; no 5.° não houve diferença significante; o número de repastos nos machos foi maior do que o das fêmeas, apenas no 5.° estádio. O peso inicial dos insetos foi maior, à temperatura de 25°C, em todos os estádios, exceto no 1.°; as fêmeas, à temperatura de 25.°C, tiveram peso maior do que o dos machos nos 4.° e 5.° estádios e, à temperatura de 30°C, apenas no 5.° estádio. Foi observado o efeito da temperatura e do sexo sobre a resistência ao jejum do T. sordida que, após a muda para os estádios consecutivos, não foram mais manipulados e nem receberam qualquer quantidade de alimento. Observou-se que a resistência média ao jejum, medida em dias, foi maior em todos os estádios do ciclo evolutivo, porém na fase adulta ocorreu interação temperatura-sexo. A correlação entre a resistência ao jejum e o último peso do estádio imediatamente anterior foi a única que se mostrou sistematicamente positiva, sendo significante em apenas oito das doze possíveis, considerados todos os estádios.

The behavior of Triatoma sordida maintained in stoves with relative atmospheric humidity of 60-70% and temperatures, respectively, of 25°C and 30°C was observed. The higher temperature caused a shortening of the growth phases. The growth of the fifth instar took longer in males than in females. The longevity of adult females was greater than that of males. With regard to ingested blood higher averages were observed at 25°C, except in the 5th instar, and the females had the highest averages in the 4th and 5th instars. With regard to the number of repasts, at 25°C the average was higher in the 1st, 2nd and 3rd instars; there was interaction of temperature and sex in the 4th instar and there was no significant difference in the 5th instar; the number of repasts of males was larger than that of females only in the 5th instar. The initial weight of triatomid bugs was greatest at 25°C in all the instars except the 1st; females at 25°C had greater weight than males in the 4th and 5th instars and at 30°C in the 5th instar only. Effects of temperature and sex in the starvation resistance of T. sordida were observed. The triatomid bugs were not manipulated or fed after the move to instar study. The average of starvation resistance measured in days was longer in all the instars of the growth cycle, but, in the adult phase, there was interaction of temperature and sex. The correlation between starvation resistance and the last weight of the immediately previous instar was the only one that was consistently positive, being significant in eight only of the twelve possible correlations. |
