“…C. orichalcociliellus, a pest of maize and sorghum, occurs in coastal East Africa, Malawi, and Madagascar at altitudes below 600 m (51, 108,127). C. aleniellus has been reported as a pest of rice in West and Central Africa and more recently as an important pest of maize in Ivory Coast (120). C. ignefusalis is the dominant stem borer of millet in the Sahelian zone of West Africa (69).…”

▪ Abstract Cereals (maize, sorghum, millet, rice) are extremely important crops grown in Africa for human consumption. Of the various insect pests attacking cereal crops in Africa, lepidopteran stem borers are by far the most injurious. All 21 economically important stem borers of cultivated grasses in Africa are indigenous except Chilo partellus, which invaded the continent from India, and C. sacchariphagus, which has recently been found in sugarcane in Mozambique. C. partellus is competitively displacing indigenous stem borers in East and southern Africa. A parasitoid, Cotesia flavipes, was introduced from Pakistan for biological control of C. partellus and caused a 32–55% decrease in stem borer densities. This article is an attempt to summarize the status of knowledge about economically important cereal stem borers in Africa with emphasis on their distribution, pest status and yield losses, diapause, natural enemies, cultural control, host plant resistance, and biological control. Special attention is given to Busseola fusca and C. partellus, the most important pests of maize and grain sorghum.

“…Chaetotaxy studies of Chilo aleniellus were carried out by Moyal & Tran (1992). They assumed, based on the drawings of C. orichalcociliellus made by Delobel (1975) and Mathez (1972), that the two species could be separated by counting the microscopical setae on the mesothorax, third and seventh abdominal segments and the head.…”

Descriptions are given of the larval stages of the 15 most damaging African stemborer species, belonging to the genera Chilo Zincken, Coniesta Hampson, Eldana Walker, Maliarpha Ragonot, Scirpophaga Treitschke (Pyralidae), Sesamia Guenee and Busseola Thurau. Chaetotaxy of the larvae has been studied. Previously published studies on the same subject are discussed. A key is provided for the identification of the genera, and where possible, the species.

“…CROP LOSSES OF MAIZE, Zea mays (L.), in Côte d'Ivoire are mainly caused by borers and by maize streak virus (Moyal 1988a). Seven species of borers, all Lepidoptera, are known to attack maize (Moyal and Tran 1992). Two of them, mainly stem borers, are dominant: Eldana saccharina Walker (Pyralidae), which generally begins attack from 50-60 d after emergence; and Busseolu fuscu (Fuller) (Noctuidae), a species that lays its eggs on maize between 20 and 40 d after emergence.…”

Statistical Model of Crop Losses Caused by Maize Stem Borers (Lepidoptera: Noctuidae, Pyralidae) in Côte d'Ivoire

Six experiments were conducted in the savanna and forest areas of Côte d'Ivoire to study the influence of stem borers on maize crop yield components and production. Statistical models showed the effect of the oldest preimaginal instars of 2 stem borers, Elduna saccharina Walker (Pyralidae) and Busseola fusca (Fuller) (Noctuidae). Plant destruction was mainly caused by early attack of B. fusca Attack by both borers on or about the 60th d after emergence induced pIant sterility. Stem borers had no direct effect on number of grains per cob-carrying plant: the level of this yield component was set according to the level of the previously determined components through a compensation phenomenon. The last yield component, average weight of grain, decreased with attack by E. sacchadna occurring on or about the 80th d after emergence. Effects of borer aggregation, maize variety, and maize streak virus incidence were studied. The statistical model of crop loss, which explains 81.7% of the variation in yield, was validated from the results of 3 trials that were not included in the regression analysis. It enables one to estimate accurately crop losses in most of Côte d'Ivoire with only 2 samplings during the growing season, on the 40th and 80th d after emergence.
