Abstract

Field studies on oviposition site, preference and pattern of Busseola fusca on various stages of maize were conducted at Awassa (southern Ethiopia). The positions of egg masses in terms of leaf sheath and height from the ground were described for different ages of the maize plant. Irrespective of the age of maize plants, eggs were laid on the under side of leaf sheaths. Busseola fusca moths showed ovipositional preference to younger maize plants. Significantly fewer egg masses were laid on older plants (r=.0.98, P <0.001). A strong relationship between maize plant age and position of egg masses was found. During the post-tasselling stage the great majority of the egg masses were found below the primary ear.

Résumé

Des études sur terrain portant sur le type et la préférence de lieu de ponte de Busseola fusca à différentes stades de développement du maïs ont été conduites à Awassa (Sud de l'Ethiopie). Les emplacements des masses d'oeufs par rapport à la gaine de la feuille et à sa hauteur par rapport au sol ont été décrits pour différents âges du maïs plante. Indépendamment de l'âge des plantes, les oeufs ont été déposés sur la face inférieure des gaines des feuilles. Le papillon de nuit, B. fusca, a montré une préférence de ponte pour des plantes de maïs plus jeunes. Significativement peu de masses d'oeufs ont été déposés sur des plantes plus âgées (r=-0,98; P <0,001). Une forte relation a été trouvée entre l'âge du maïs et l'emplacement des masses d'oeufs. Au cours de la phase postérieure à la formation de l'épi, la grande majorité de la masse d'oeufs a été trouvée sous l'épi primaire.
