Nottingham Entomology

Welcome!  The Nottingham Tree Fruit Entomology lab is based out of WSU’s Tree Fruit Research and Extension Center in Wenatchee WA. Our primary goal is improving insect and mite pest management practices in commercial tree fruit orchards. Topics include insect behavior, phenology, biological control, cultural control, and chemical control.
