  1. 21. Biological control of plant-parasitic nematodes by the fungus Clonostachys rosea

    Författare :Mudassir Iqbal; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : Plant diseases caused by plant-parasitic nematodes are serious constraints to sustainable crop production due to high yield losses, the persistent nature of these nematodes and a lack of efficient control methods. Biological control is a promising approach to reduce plant diseases caused by nematodes. LÄS MER

  3. 22. Fruit and microbial cues in the behavioural ecology and management of Drosophila suzukii

    Författare :Guillermo Rehermann Del Rio; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Investigating the factors that determine the behaviour of new pests is essential for understanding, predicting and managing their impact on natural and agricultural ecosystems. The spotted wing drosophila (SWD), Drosophila suzukii (Matsumura; Diptera: Drosophilidae), is a worldwide spreading polyphagous pest of soft fruit and berries. LÄS MER

  4. 23. Odor perception in three Coleoptera: molecule, receptor & neuron

    Författare :Jonas Bengtsson; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : In this thesis, the sense of olfaction and its links to behavior was studied in the cetoniid chafers Pachnoda interrupta and P. marginata, and the bark beetle Ips typographus. P. interrupta is a pest on sorghum in Ethiopia, and I. LÄS MER

  5. 24. Diversified agroecosystems for biodiversity and ecosystem services : Ecological intensification of faba bean cropping under land use and climate change

    Författare :Chloë Raderschall; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Loss of natural habitats and lack of continuous floral resources in intensive agricultural landscapes limit the population growth of ecosystem service providers, such as pollinators. Weakened ecosystem service delivery and climate change stressors contribute to crop yield instability. LÄS MER

  7. 25. Insect pollination of oilseed rape

    Författare :Sandra Lindström; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Ecological intensification of agriculture is suggested as a way to reach higher crop yields without increasing inputs that may degrade the environment. Increased insect pollination in crops, such as oilseed rape, Brassica napus, has been suggested to increase yields, but is rarely integrated in crop management. LÄS MER
