“Invasive sorghum aphid: A decade of research on deciphering plant resistance mechanisms and novel approaches in breeding for sorghum resistance to aphids” with Drs. Somashekhar Punnuri, Karen Harris-Shultz, Joseph Knoll, and Xinzhi Ni.

Sorghum is an important crop in the United States, grown for grain, forage and bioenergy purposes. However, its production is facing several challenges due to abiotic and biotic factors, with aphids emerging as a significant pest in last decade. Once considered a minor pest, sorghum aphids have become a major threat to sorghum cultivation due to susceptible varieties and insufficient pest management strategies. In this episode, Dr. Somashekhar Punnuri, an associate professor from Fort Valley State University; Drs. Karen Harris-Shultz and Joesph Knoll, research geneticists with USDA ARS; and Dr. Xinzhi Ni, a research entomologist from USDA ARS, share their insights on current research efforts and new methods to combat sorghum aphids.

Tune in to learn more about:

·         What characteristics sorghum aphids have

·         How sorghum aphids reproduce

·         What resistance mechanisms sorghum has

·         What the current efforts are in breeding aphid resistant sorghum varieties

·         What the challenges are in aphid management in sorghum
