Abstract
The effect of temperature on the rate of development ofPristhesancus plagipennis Walker was determined by rearing individuals under a range of constant temperatures (22.5–35°C). Rates of development changed in a linear fashion from 22.5–30°C. Estimates of lower developmental thresholds were obtained for egg (13.1°C), nymphal (15.5°C) and egg to adult development (15.4°C). Fastest rates of nymphal and egg development occurred at 30 and 32.5°C, respectively. A requirement of 845.7 DD (degree days) was estimated for development from egg to adult. Nymphal survivorship was highest between 25 and 30°C.
Résumé
L'effet de la température sur la vitesse de développement dePristhesancus plagipennis a été déterminé par élevage des insectes dans une gamme de températures constantes allant de 22,5 à 35°C. La vitesse de développment est une fonction linéaire de la température entre 22,5 et 30°C. Le seuil théorique de développement a été estimé à 13,1°C pour l'œuf, 15,5°C pour la nymphe et 15,4°C pour le développement larvaire. Les plus grandes vitesses de développement de l'œuf et de la larve ont été obtenues respectivement à 30 et 32,5°C. 845,7 degrés-jours sont nécessaires pour le développement de l'œuf à l'adulte. La survie des nymphes a été la plus élevée entre 25 et 30°C.
