Five things to know: Colorado potato beetle  

Five things to know about: Colorado Potato Beetle

Silvia Rondon of HAREC and growers are seeing large populations of Colorado potato beetle (CPB) this year in eastern Oregon. We reached out to ask her more about this pest:

  • When are potatoes most susceptible to CPB? 
    • After planting and before-during tuber formation. There are some peer reviewed studies that report little effect on yield if cpb feeds on foliage after tuber maturation.
  • What are some IPM tactics that can be used to combat CPB?
    • Crop rotation, remove debris from previous season, insecticide at planting, border crops, biological control exists but it is limited.
  • What kinds of projects is your lab working on to manage CPB?
    • Pahoua Yang was a graduate student in my program; she graduated late December 2019. Her work focused on establishing baseline information about NW CPB population against common pesticides. Michael Crossley, a student from Univ. of Wisconsin, studied the effect of landscape on the evolution of CPB in the PNW and midwest. Find out more here: http://blogs.Oregonstate.Edu/iaep/
  • Is potato the only crop that is affected by CPB?
    • CPB affects solanaceous crops including tomato, eggplants, but CPB has a strong affinity for potatoes. I am conducting some field evaluations to determine the preference of CPB to some common potato varieties. Next year, I am enrolling a PhD student to study chemical reasons CPB prefers some varieities compared to others. Occasionally, you see them nibbling on other crops like hemp.
  • Tell us one really cool fact about CPB:  
    • Although CPB are “loyal” to potatoes, you can find them feeding on flowers of goat head. This is a very common weed in eastern oregon. I think that is super cool ..Adaptation? Evolution? We will see! 

      Silvia recently posted a couple of videos showing the huge CPB populations in Eastern Oregon and adults feeding on goat head.

New Faculty and Recent Awards

New Faculty
Dr. Christine Dodge, Faculty Reseach Assistant, Department of Crop and Soil Science

Chrissy received her Ph.D. in Entomology in 2019 from the University of California, Riverside, where she worked on invasive ambrosia beetles and their fungal symbionts. Although she’ll always hold insects (especially beetles) close to her heart, she is excited to join the Mc Donnell Lab, where her research will focus on biocontrol and management of pest snails and slugs.



Awards and Recognition
Emily Carlson, Ph. D. Student, Department of Horticulture

Emily Carlson, a PhD student at Oregon State University, studies how pesticide exposure differs between honey bees and native bees with varying landscape context. Emily  was selected for the ESA Policy Fellows Class of 2020. Notably, Emily was the only non-faculty member selected for the Policy Fellows Class. The Science Policy Fellows program is a two-year active training program to teach entomologists the skills needed to successfully advocate for the discipline.
