Abstract

Experiments were conducted in 1989 to evaluate converted sorghum accessions for preflowering extended panicle and soft-dough stage panicle feeding resistance to fall armyworm, Spodoptera frugiperda (J. E. Smith), by incorporating plant tissue into artificial insect diet. Spodoptera frugiperda biological parameters measured were larval and pupal weights, mean duration of the larval stage, time to adult eclosion, survivorship, fecundity, net reproductive rate, intrinsic rate of increase, and relative fitness. The converted lines IS 2246C, IS 2403C, IS 2825C, IS 7007C, IS 8337C, IS 12592C, IS 12612C, IS 12657C, IS 12666C, and IS 12681C were more resistant to both preflowering and soft-dough stage panicle feeding by S. frugiperda than the resistant check NK Savanna 5. The genotypes IS 1340C, IS 2553C, IS 2569C, IS 6911C, IS 7498C, IS 12219C, IS 12617C, IS 12662C, and IS 12664C were more resistant than the resistant check to S. frugiperda feeding in the soft-dough stage, but not in the preflowering stage of panicle development. Plant antibiosis was the major mechanism of resistance in these lines at both stages of the panicle development.

Résumé

Des lignées naines de sorgho, Sorghum bicolor (L.) Moench ont été évaluées pour déterminer leur résistance à la chenille légionnaire, Spodoptera frugiperda (J. E. Smith) durant la phase préfloraison et la phase patte douce de la panicule. La resistance a été étudiée en incorporant des échantillons de panicule des différentes lignées dans le diète de l'insecte. Les paramètres biologiquesde l'insecte qui ont été mesurés étaient le poids des larves, le poids des nymphes, la durée de la phase larvale, le temps d'apparition de 1'adulte, le taux de survivance, la fécondité, le taux net de réproduction, le taux intrinsec d'accroissement et l'aptitude relative. Les lignées naines IS 2246C, IS 2403C, IS 2825C, IS 7007C, IS 8337C, IS 12592C, IS 12612C, IS 126S7C, IS 12666C et IS 12681C étaient plus résistantes à la chenille que le témoin résistant NK Savanna 5 durant la phase préfloraison aussi bien que la phase patte douce de la panicule. Les lignées IS 1340C, IS 2S53C, IS 2S69C, IS 6911C, IS 7498C, IS 12219C, IS 12617C, IS 12662C et IS 12664C étaient plus résistantes que le témoin résistant durant la phase patte douce de la panicule, mais pas durant la phase préfloraison. L'antibiose était le méchanisme majeur de la résistance chez ces lignées de sorghoaux deux phases de la panicule qui ont été testées.
