Effect of fluctuating temperature and humidity on the longevity of starved Rhodnius prolixus (Hem., Triatominae)
Journal of Applied Entomology - Zeitschrift für angewandte Entomologie 122 (5), 219-222
Abstract: The survival potential of newly emerged unfed and starved Rhodnius prolixus nymphs was studied under various regimes of fluctuating temperatures between 15 and 35°C and humidities between 43 and 97%. Both temperature and humidity were found to have an impact on survival. With fluctuating conditions at 12/12 h, survival of first instar nymphs was the longest after exposure to lower temperatures and elevated humidities. Longevity diminished with increasing temperatures at lower humidities. At alternating extreme humidity, high 97% and low 43%, nymphs were more sensitive to starvation than after combining extreme humidity 97 or 43% with humidity of 75 or 86%, independent of temperatures. First instar nymphs were more sensitive to starvation, than third and fifth instars.
