Abstract

The effects of different degrees of stem tunneling caused by different levels of artificial infestation by the larvae of Chilo partellus (Swinhoe) on growth and yield of 4 maize cultivars were studied. The susceptible ‘Inbred A’ suffered much more tunneling than ICZ1‐CM, ICZ2‐CM and Katumani Composite B. This tunneling influenced significantly the plant growth of all the four cultivars. There was a significant negative correlation between tunneling and yield for the cultivars ‘Inbred A’ and Katumani Composite B, but such a relationship was not significant for ICZ1‐CM and ICZ2‐CM. Such differences in the relationships between tunneling and yield among the 4 cultivars are due to different degrees of tunneling caused by C. partellus larvae to the plants of these cultivars. Chilo partellus: influence de ses dégâts sur la croissance et la récolte de certains cultivars demaïs L'étude a porté sur la croissance et la production avec différents niveaux de minage des tiges de 4 cultivars de maïs, lors de divers degrés de contamination artificielle par des chenilles de C. partellus. Le cultivar sensible ‘Inbred A’ souffre plus des mines de C. partellus que ICZ1‐CM, ICZ2‐CM et Katumani composite B. Les mines influent significativement sur la croissance des 4 cultivars. Il y a une corrélation négative significative entre le minage des tiges et la production pour les cultivars ‘Inbred A’ et Katumani composite B, mais la relation n'est pas significative pour ICZ1‐CM et ICZ2‐CM. Les différences entre le minage des tiges et la récolte des 4 cultivars sont dues aux différents degrés de minage des tiges de ces cultivars par C. partellus. 1988 The Netherlands Entomological Society
