| Résumé : |
To assist plant breeders in obtaining suitable material for screening sorghum resistance to storage insect attack, test grain from a susceptible variety was used to determine the best combination of minimal trial material with optimal infestation. Three masses of 10, 15 and 20g were infested with 10,15,20,25,30,35 and 40 10-day-old adult weevils (Sitophilus oryzae) and with the same quantities of eggs of the grain moth (Sitotroga cerealella). Results are discussed according to progeny output in relation to infestation levels and grain mass. Combinations of 30 weevils and 20g of grain and 40 grain moth eggs and 15g of grain are recommended for use in further resistance screening. |
