Abstract

A degree-day model was developed for Alberta populations of Ostrinia nubilalis Hübner. Starting with overwintered fifth-instar larvae, the model calculates the temporal distribution of first- and second-instar larvae which are the stages most vulnerable to chemical suppression. Predictions from three alternative models were compared against field data from southern Alberta. Use of a standard 10°C growth threshold to calculate physiological time scales allowed predictions as accurate as those obtained using either a pooled threshold (11.4°C) calculated specifically from Alberta populations, or a model using two thresholds (12.3°C for fifth-instar larvae to adult and 10.2°C for eggs to second-instar larvae) that incorporated significant differences in growth characteristics observed among life stages. We conclude that standard thresholds are sufficient for degree-day models for northern populations of O. nubilalis. The standard model (t 0 = 10°C) predicts that moth emergence will peak at ca. 145 degree-days after median pupation, and that numbers of eggs, and first- and second-instar larvae should peak at 200, 310, and 450 degree-days, respectively. Model predictions can be used to time sampling effort in support of management decisions.

Résumé

Un modèle de degrés-jours a été développé concernant les populations d’Ostrinia nubilalis Hübner en Alberta. Débutant avec les larves hivernées du cinquième stade, le modèle estime la distribution temporelle des larves du premier et du deuxième stade, qui sont les plus vulnérables à la suppression chimique. Les prédictions issues de trois modèles différents ont été comparées avec les données obtenues dans le champ au sud de l’Alberta. L’utilisation d’un seuil de croissance normal de 10°C pour estimer les échelles physiologiques temporelles a permis des prédictions aussi valables que celles obtenues par l’utilisation soit d’un seuil accru (11,4°C) calculé spécifiquement à partir des populations de l’Alberta, soit d’un modèle qui utilise deux seuils (12,3°C en ce qui concerne le développement du cinquième stade larvaire à l’adulte et 10,2°C en ce qui concerne le développement de l’oeuf aux larves du deuxième stade), qui ont incorporés des différences significatives des caractères de croissance constatées parmi les stades vitaux. Nous avons conclu que les seuils normaux sont suffisants pour les modèles degrés-jours pertinents aux populations septentrionales d’O. nubilalis. Le modèle normal (t 0 = 10°C) prédit que l’éclosion des adultes atteindra son apogée à ca. 145 degrés-jours suivant la date de nymphose moyenne et que les nombres d’oeufs et de larves du premier et du deuxième stade devraient atteindre leurs apogées à 200,310 et 450 degrés-jours, respectivement. Les prédictions obtenues en utilisant les modèles peuvent être employées pour appuyer les décisions de gestion par la détermination de l’heure d’échantillonnage.
