Barley Yellow Dwarf Virus (BYDV) is extensive and economically important
Includes Virus, vector, and host
Disease epidemics affect ecosystems and biodiversity
grasslands serves as
This project focuses on vector behavior as indication of disease movement and structure
BYDV cannot be transmitted directly
Determined largely by aphids!
Objective: To study characteristic factors that
reflect aphid presence to
gain a better idea of BYDV’s
spatial epidemiology in the

Overall slight downward trend in Elevation for Aphid Count disease movement and structure
Increase in elevation with road habitat has a distinct correlation with the increase in aphid countResults for Elevation
are influencing aphid feeding preference
