Abstract

Rates of development of selected stages and complete development of the carrot weevil, Listronotus oregonensis (LeConte), were determined in the laboratory at controlled temperatures ranging from 17.5 to 30°C. Within that range of temperature, rates of development increased with temperature. Fitting the data to a cubic polynomial function provided an excellent description of the relationship between temperature and rate of development for all stages as shown by R2 values of at least 0.98.

Résumé

Les taux de développement de stades choisis et de développement complet du charançon de la carotte, Listronotus oregonensis (LeConte), ont été établis en laboratoire, à des températures contrôlées variant de 17,5 à 30°C. Les travaux ont révélé que ces taux augmentaient avec la température. Le traitement des données selon une fonction polynomial de 3e degré offrait une excellente description de la relation entre la température et le taux de développement pour tous les stades, comme le montrent les valeurs du carré du coefficient de corrélation linéaire, qui s’établissaient à au moins 0,98.
