General Information:

Damsel Bugs (a.k.a. “Nabids”) — Nabis spp. are generalist predators in crops and natural settings, with specialized front legs for grappling prey, and piercing-sucking mouth parts for sucking body fluids of prey.

Biology and Life History:

  • Damsel bugs are common nearly everywhere potatoes are grown in the Pacific Northwest.
  • Adult damsel bugs colonize potato fields in later spring, and nymphs can be found during the summer months.
  • In addition to aphids and Lygus, damsel bugs will feed on caterpillars like loopers and armyworms, and the eggs and young larvae of Colorado potato beetle.
  • Like all beneficial insects in potatoes, damsel bugs are very sensitive to broad-spectrum insecticides such as pyrethroids.

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 Raina Spence, Manager of the Consortium.
