Abstract

The population dynamics of the European corn borer, Ostrinia nubilalis (Hübner) (Lepidoptera: Pyralidae), were documented on potatoes grown in Prince Edward Island (P.E.I.) from 1990 to 1992. By comparing degree-day accumulations above 10°C, both first occurrence and peak flights of male adults occurred earlier than elsewhere in North America. Because potatoes in P.E.I. are attacked earlier and over a longer period of time than potatoes grown in other regions, the insect is an important pest of potatoes in P.E.I. The correlation between peak numbers of male adults caught in pheromone traps and egg masses on potato plants was not significant (p = 0.22). However, the correlation between egg masses per potato stalk and larvae per potato stalk was significant (p = 0.003). Trapping adults and monitoring potato plants for the presence of egg masses during the period from 250 to 500 degree-days appears to be a reliable way to determine the presence of adults and the potential impact of larvae on yield of potatoes.

Résumé

La dynamique des populations de Pyrales du maïs, Ostrinia nubilalis (Hübner) (Lepidoptera : Pyralidae), a été étudiée dans des cultures de pommes de terre de l’Île-du-Prince-Edouard, de 1990 à 1992. D’après les sommes de degrés-jours au-dessus de 10°C, l’apparition et l’abondance maximale des mâles adultes se produisent dans cette région plus tôt que partout ailleurs en Amérique du Nord. Les cultures de pommes de terre de l’île sont donc envahies plus tôt et pour plus longtemps que les cultures d’autres régions et l’insecte est donc un ravageur important des pommes de terre dans l’Île-du-Prince-Édouard. La corrélation entre le nombre maximal de mâles adultes recueillis dans les pièges à phéromone et le nombre de masses d’oeufs recueillies sur les plants de pomme de terre n’était pas significative (p = 0,22). Cependant, la corrélation entre le nombre de masses d’oeufs et le nombre de larves par plant s’est avérée significative (p = 0,003). Le piégeage des adultes et l’examen des plants de pommes de terre pour y repérer les masses d’oeufs durant la période 250–500 degrés-jours semblent des moyens adéquats de détection de la présence d’adultes et d’évaluation de l’impact des larves sur les récoltes de pommes de terre.
