Parasitic Wasps & Flies (Parasitoids)

Adult of a caterpillar-killing parasitoid

General Information:

Many insects are preyed upon by specialized parasites known as “parasitoids.” A parasitoid lives in or on its host, leading inevitably to host death. Most pest insects in potato fields are attacked by parasitoids, especially in organic fields or conventional fields with few insecticide applications (generally, parasitoids are very sensitive to insecticides).

About The Northwest Potato Research Consortium

In February 2012 the state potato commissions in Washington, Idaho, and Oregon officially launched a new cooperative effort in research. The aim of this initiative is to increase cooperation and efficiency of the research programs funded by the three potato commissions that total about $1.5 million annually. It will also work toward comprehensive research results reporting process that aims to get useful information to the growers and industry members who need it. This website is a big part of that effort. Research results, integrated pest management guidance, and production information of many kinds will be presented here. For feedback or suggestions on this site, please contact Andy Jensen, Manager of the Consortium.
