Summary

Potato leaf roll virus (PLRV) and Potato virus Y (PVY) are the two most serious viral diseases affecting potato growers in North America. Each virus is characterized by a distinct epidemiology and should be treated accordingly. This presentation will help consultants, growers, and other practitioners in North America to optimize insecticide use for controlling aphid vectors of PLRV and PVY in their crops. Practitioners will learn the differences between persistently and nonpersistently transmitted viruses and between colonizing and noncolonizing aphid species, as well as their implications for making proper decisions on using insecticides. 

About the Presenter

Andrei AlyokhinAndrei Alyokhin received a PhD in Entomology in 1999 from the University of Massachusetts in Amherst, where he worked on insecticide resistance in the Colorado potato beetle. After spending 2 years as a postdoctoral research associate at the University of Hawaii, he returned to studying insect pests of potato as an Assistant Professor of Applied Entomology at the University of Maine. His major areas of research interest are applied insect ecology, evolution, insect behavior, and integrated pest management. He is also interested in more theoretical investigations of factors responsible for growth and diversity of insect populations.​
