Abstract

Forty exotic maize inbred lines from 10 countries with known resistance or susceptibility to the European corn borer, Ostrinia nubilalis (Hübner), were used to study the effect of plant resistance on borer survival from natural overwintering conditions and particularly the fecundity of the female moth during the following summer. Also, additional information was obtained on different biological characters of the insect. Resistant and susceptible lines were grouped according to their leaf feeding ratings (antibiosis), per cent borer survival at pollination time or at harvest (tolerance). Each specimen observed was kept on the same plant tissue until pupation. The number of eggs and egg masses/female was significantly higher only when lines are grouped according to their leaf feeding ratings. No significant differences were obtained in most biological characters of borers fed on resistant or susceptible maize lines: spring pupation, pupal parasitism, mortality and weight, moth emergence and sex ratio.

Résumé

Quarante lignées de maïs connues pour leur résistance ou leur sensibilité à la Pyrale du maïs Ostrinia nubilalis (Hübner) venant de dix pays, ont servi à l’étude de l’effet de la résistance des plantes vis-à-vis la survivance de l’insecte dans des conditions naturelles d’hivernement et notamment, la fécondité des papillons femelles l’été suivant. Des données additionelles sur différents charactères biologiques de l’insecte ont aussi été obtenues. Chaque individu étudié s’est nourri de la même lignée de maïs jusqu’à sa métamorphose printanière. Les lignées résistantes et sensibles à la Pyrale furent groupées selon la criblure du feuillage ou phénomène d’antibiose de la plante, le pourcentage de survie des larves à la pollinisation ou à la récolte des plantes (tolérance). Le nombre d’œufs ou de pontes par femelle a été significativement plus grand seulement lorsque les lignées sont groupées selon la criblure du feuillage. Aucune différence significative dans le comportement vital de l’insecte a été observée entre individus nourris sur du maïs résistant ou sensible, c’est-à-dire la chrysalidation printanière, la mortalité, le parasitisme ou le poids chez la chrysalide, ainsi que l’émergence des adultes et leur sexe.
