Abstract

A 5-year study of a bivoltine strain of the European corn borer, Ostrinia nubilalis (Hübner), showed that first-generation moths deposited more eggs on early-planted corn, whereas second-generation moths oviposited more frequently on late-planted corn. The second generation was much larger than the first generation and caused the greater reduction in yield, regardless of whether the yields were based on physiological losses or a combination of physiological losses and dropped ears. It was shown that delay of harvest beyond the time that moisture content of the corn was sufficiently low for machine harvesting could result in severe yield losses from broken stalks and dropped ears during autumn storms.

Résumé

Une étude de cinq ans d’une lignée bivoltine de la pyrale du maïs, Ostrinia nubilalis (Hübner), a révélé que les femelles de première génération déposaient plus d’oeufs sur du maïs précoce, alors que les femelles de seconde génération en pondaient davantage sur du maïs tardif. La seconde génération est beaucoup plus nombreuse que la première et cause la plus grande baisse de rendement, peu importe si celui-ci s’appuie sur des pertes physiologiques (p.p.) ou sur une combinaison de p.p. et de chute des épis. L’étude révèle que le recul de la récolte après l’époque où la teneur en eau du maïs est assez basse pour permettre la rçolte mécanique pouvait entraîner des baisses de rendement substantielles par rupture des tiges ou chute des épis au cours des tempêtes automnales.
