Filbert aphids mate in the fall and then lay eggs, which will overwinter on hazelnut trees. The aphids then hatch in the spring and move onto developing buds and shoots to feed. Here are some photos of filbert aphids mating, and also eggs that have been deposited at the bases of buds.
Parts of the Willamette Valley were hit hard by a weather system that brought snow and freezing rain mid February. Some orchards were devastated by the damage when branches and even entire tree trunks were split by heavy accumulations of precipitation.
This video discusses the amazing little samurai wasp that attacks brown marmorated stink bugs. Much of the footage was filmed at the North Willamette Research and Extension Center!

The Wiman lab welcomes Rachele (Pronounced: RAH-Kelly) Nieri as a new postdoctoral research associate. She comes to the Wiman lab from Italy with a background in the study of insect communication. Rachele’s research will focus on spotted-wing drosophila behavior in an effort to improve management strategies.
Congrats to Heather, Aaron, and David on receiving Clackamas County Innovative funds! Heather’s project will set up a high-quality photo system. Aaron’s project will develop a network and workshop on growing hard cider apples. David’s project will study wild pollinators in our experimental peach and cider apple plots.
