Abstract

Lepidopterous stem-borers are the most serious and widely distributed insect pests of sorghum. Among the several avenues of their control, the use of resistant varieties holds good prospects. In order to identify the sources of resistance to stem-borers (Chilo partellus, Busseola fusca, Eldana saccharina and Sesamia calamistis), a large number of sorghum lines from Kenya, India and Texas, U.S.A. have been screened under a very heavy natural infestation in Western Kenya. Several promising lines with resistance potential have been identified for the stem-borer complex which include: IS 10370, L-2 (TX 2780), IS 10364, IS 1044, S-178, IS 3962, IS 4213, IS 12447, IS 18479, IS 18326, L-l (A&B TX 2756), IS 4405, IS 10711, IS 18676, IS 5613, IS 18517, IS 18323, IS 4881, IS 1151 and IS 18427.

Résumé

Les rongeurs de tige Lépedoptères sont les insectes s'attaquant au sorgho les plus sérieux et les plus couramment rencontrés. Parmiles différentes méthodes de contrôle, l'utilisation des variétés résistantes a de bonnes chances de réussite. Pour identifier les sources de résistance aux rongeurs de tiges (Chilo partellus, Busseola fusca, Eldana soccharina et Sesamia calamistis), un grand nombre de lignées de sorgho provenant de l'Inde, Kenya, Texas (U.S.A.) a été examiné dans des conditions d'infestation massive naturelle au Kenya occidental. Plusieurs lignées prometteuses avec un potentiel de résistance ont été identifiées pour le rongeur de tige. Elles comportent: IS 10370, L-2 (TX 2780), IS 10364, IS 1044, S-178, IS 3962, IS 4213, IS 12447, IS 18479, IS 18326, L-1 (A et B TX 2756), IS 4405, IS 10711, IS 18676, IS 5613, IS 18517, IS 18323, IS 4881, IS 1151 et IS 18427.
