  2. 11. Attract, reward and disrupt: combining habitat manipulation and semiochemicals to enhance pest control in apple orchards

    Author : Joakim Pålsson; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : Agricultural intensification entails negative effects on natural enemy populations and the pest regulation services they provide. Habitat manipulation holds potential to control pests with less negative effects on the environment than conventional methods. READ MORE

  4. 12. A tale of two blights

    Author : Sophie Brouwer; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : Potato is the third most important food crop for human consumption. However, the production is plagued by several pests and pathogens causing yield reducing diseases. Estimations indicate that 17% of the global potato yield is lost due to pests and pathogens. READ MORE

  5. 13. Revisiting push-pull technology: Below and aboveground mechanisms for ecosystem services

    Author : Aneth Bella David; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : Push-pull technology is an effective and ecological solution to suppressing major Lepidopteran pests of cereals, in particular stem-borers (Busseola fusca, Chilo partellus), the fall armyworm (Spodoptera frugiperda) and the parasitic weed Striga. The technology exploits plant-insect interactions in intercropping practices to manage the pests, increasing productivity while maintaining ecosystem resilience. READ MORE

  6. 14. The Scents of Nature : Identification and Synthesis of Bioactive Compounds Used in Insect Communication

    Author : Erika Wallin; Erik Hedenström; Anna-Karin Borg-Karlson; Mittuniversitetet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Semiochemicals; Sex pheromone; Bicyclus spp; Euglossa spp; Cimex hemipterus; Cimex lectularius; Kladothrips nicolsoni; Kladothrips rugosus; Drosophila melanogaster;

    Abstract : Pest insects cause great financial losses in the forest and food industry every year. To fight these pests industries have used insecticides, which are sometimes harmful to nature and humans. READ MORE

  7. 15. Plant resistance ecology - the role of resistance in plant-insect mutualisms

    Author : Daniela Weber; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : Global food security is largely dependent on the use of synthetic pesticides for pest control. This extensive reliance on pesticides, however, has promoted widespread loss of insect diversity; thereby jeopardizing the provision of insect ecosystem services like pollination and biological control.
