Native Stink Bugs and their Plant Hosts

with Jim Hepler

February 7, 2020

On February 7, 2020, Jim Hepler, of the Beers Laboratory at WSU’s Tree Fruit Research and Extension Center, joined us to share his extensive knowledge (and humor) of native stink bugs and their life history. He gave an enlightening overview of the diversity of stink bugs found in eastern Washington, and expounded on the challenges and rewards, and all that is known and unknown about these creatures. Jim’s palpable interest was contagious, sparking the curiosity of our local community.

Fun facts:
-Stink bugs can drill through nut husks to feast on the nutrient-rich innards
-Pesticides are futile in fighting stink bugs since they are constantly on the move into and out of orchards
-Stink bugs have very specific relationships with other insects who will lay their eggs inside stink bug eggs or drill through adults’ exoskeletons to feast
-Stink bugs are very capable of killing themselves with their own noxious fumes!
