Areas of Interest

Integrated pest management of insect pests of potato, with emphasis on insects vectoring potato diseases. Current research includes management of aphids, leafhoppers, potato leafroll virus (PLRV), potato virus Y (PVY), and phytoplasmas. Also, studies to enhance biological control of green peach aphid using predator attractants and habitat modification and to assess the effectiveness of biorational insecticides to reduce virus spread in potatoes are an integral component of my research.
