  4. 3. Preferences of the common garden ant (Lasius niger) in choice of aphid mutualist : Possibilities to increase biological control of the rosy apple aphid (Dysaphis plantaginea)

    Kandidat-uppsats, SLU/Dept. of Biosystems and Technology (from 130101)

    Författare :Olle Danielsson; [2015]
    Nyckelord :Aphid; ant; Lasius niger; mutualism; biological control; rosy apple aphid;

    Sammanfattning : The aim of this study is to acquire knowledge about the preferences regarding aphids of the ant Lasius niger (common garden ant), commonly found attending aphids and protecting them agains their natural enemies in apple orchards around the world. By knowing this, it is hypothesized that another plant can be brought into an orchard carrying another aphid, more suitable as an ant-mutualist, to compete with the pest aphid present on site. LÄS MER
