Impact of Sorghum Genotypes on Nymphal Development and Reproduction of Melanaphis sacchari

Abstract

Sorghum (Sorghum bicolor (L.) Moench), a tropical grass originating from Africa, serves as a staple food source for both humans and livestock. The global expansion of sorghum cultivation, particularly in Brazil and the United States, has facilitated the spread of the sugarcane aphid, Melanaphis sacchari (Zehntner) (Hemiptera: Aphididae), a highly adaptable pest. This study evaluated adult fecundity and nymphal development of M. sacchari in 12 sorghum genotypes to identify potential sources of re
