Biography

Dr. Sanford Eigenbrode received a BS, MS and PhD from Cornell University. Sanford conducts research on chemical ecology of insects, plant-insect interactions, chemical and structural plant attributes affecting plant-insect and tritrophic interactions, insect behavior, plant surface waxes, with expertise in extraction and analysis of chemicals from plant tissues, scanning electron microscopy, host plant resistance, and integration of host plant resistance into pest management. Interests also include the effects of crop variety and management practice on arthropod communities in agroecosystems. Research in this area includes effects of tillage practices on ground-dwelling insect predators in wheat and pea and in the surrounding landscape. Similar questions are being addressed concerning ant communities in coffee systems in Costa Rica. These last two emphasis areas are part of a larger training and research project funded by NSF/IGERT at the University of Idaho and CATIE in Costa Rica. more info

Title: The Invasive Species Project: Spotted Knapweed (Centaurea stoebe)
Department: Plant, Soil & Entomological Sciences (PSES), and Forest Resources

Project Summary

Spotted knapweed is one of Idaho’s most environmentally invasive and aggressive non-native plants. In previous greenhouse experiments we have shown that knapweed and its competitors are affected by endophytes in the absence of mycorrhizae. In addition, we have found that certain endophyte isolates differ in their susceptibility to attack by aphids and by the flower-feeding weevil Larinus minutes. This weevil has been released in North America for management of the biologically invasive Centaurea spp. The goal of this long-term project is to improve the management of invasive spotted knapweed; in this phase of the project, the REU student will test the relationship between C. stoebe and Larinus minutes, a weevil used for biological control of invasive plants.
