    Sammanfattning : Ips typographus (Coleoptera: Curculionidae, Scolytinae) is a pest species that mainly attacks Norway spruce (Picea abies L. Karst.) and can kill large volumes of spruce trees during outbreaks, leading to economic losses of great magnitude. A common practice to manage attacks is to remove recently killed trees and thereby remove the beetles. LÄS MER

  4. 13. Tritrophic interactions with Silphium integrifolium at the axis : elucidating the role of arbuscular mycorrhizal fungal species on plant phenotype

    Master-uppsats, SLU/Dept. of Plant Protection Biology

    Författare :Philipp Hansen; [2023]
    Nyckelord :Arbuscular mycorrhiza; mycorrhizal responsiveness; induced plant volatiles; Silphium integrifolium Silflower ; perennial grains; new crops; ecological intensification;

    Sammanfattning : A fundamental understanding of the intricate interactions between crops and their environment may help guide the development of ecologically intensified agriculture. Arbuscular mycorrhizal fungi (AMF) are root symbionts that can increase a plant’s access to soil resources and have been found to reprogram plant defensive mechanisms, potentially influencing the performance of plant antagonists.
