Sugarcane Aphid Resistance In Pearl Millet, D. D. Serba, J. P. Michaud

Kansas Agricultural Experiment Station Research Reports

Sugarcane aphid, (Melanaphis sacchari(Zehntner) (Hemiptera: Aphididae)) has become an important pest of sorghum in the US. This recent invasion is assumed to be either as a result of a host shift from sugarcane in the south or introduction of a special­ized strain from tropical Africa. If host shift happened through adaptive change to infest sorghum, other closely related species such as pearl millet are in danger from this voracious pest. The resistance level of pearl millet genotypes representing A-, B-, R-lines and germplasm were evaluated under climate-controlled growth chamber along with resistant and susceptible sorghum hybrids. Ten plants …
