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