Hi! My name is Tiziana Oppedisano and I recently joined the Western Triangle Agricultural Research Center as Assistant Professor of Entomology/Insect Ecology.
I completed my studies in biology and entomology in Italy. My doctoral research focused on the biology and ecology of the insect vectors of apple proliferation, a disease of economic importance in apple-growing areas across Europe.
In 2019, I moved to the USA to start a position as a postdoc researcher at the Hermiston Agricultural Research and Extension Center (Oregon State University). My main postdoctoral projects focused on studying the role of leafhoppers as vectors of phytoplasma and virus diseases in field crops and industrial hemp of the Columbia Basin, with the aim to improve local Integrated Pest Management programs. I contributed to many other projects, including studies on variety trials aim to identify varietal resistance to certain pests, and application of agronomic practices to decrease pests populations.
I am an active member of the Entomological Society of America, and I also enjoy being involved in local outreach events.
Please reach out for any arthropod pest concern, I will be happy to help!

My research focuses on integrated management of agricultural arthropod pests, and it is mainly based on growers and other stakeholders needs.
I am interested in exploring and improving our understanding of pest biology and ecology in crop systems and applying that information to develop practical, cost-effective, and environmentally sensitive pest management tactics.
The primary focus of my research program at WTARC is on insect pests of small-grain, pulse, and oilseed crops in the Golden Triangle. Target pests include the wheat stem sawfly and wireworms in wheat, pea leaf weevils in pulses, and flea beetles in canola.
