  1. 16. Co-developing pest management for organic apple production : combining participatory action research, activity theory, laboratory and field trials in a Swedish context

    Författare :Weronika Swiergiel; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : Participatory Action Research (PAR) is an interventionist, action-orientated and transdisciplinary approach to applied research that strives for the collaborative development of any practice together with relevant stakeholders. It enhances the relevance of research to practice by active stakeholder involvement in all research steps, including the spaces in which the practice is conducted, its iterative knowledge construction and the recognition that knowledge exists in practice and is created when attempting to transform reality.

  2. 17. Acute pesticide poisonings in Nicaragua : underreporting, incidence and determinants

    Författare :Marianela Corriols Molina; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Pesticide poisonings; surveillance system; underreport; incidence; economic costs; determinants; integrated pest management;

    Sammanfattning : Background: Acute pesticide poisonings (APP) are a public health problem in Nicaragua. The quality and coverage of APP´s register, the real incidence of APP, the main determinants, the economic cost of treating cases and the effectiveness of educational intervention are not well known.

  3. 18. Local and landscape-level impacts of agricultural intensification on arthropod communities and their interaction networks

    Författare :Guillermo Aguilera Nuñez; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Arthropods play a central role in agricultural landscapes being responsible for the delivery of many ecosystem services such as pollination, biological pest control, and nutrient cycling. But the current global decline of arthropods is intensified by habitat modification, loss and fragmentation, pesticide use and other intensive management practices. LÄS MER

  4. 19. Plant resistance ecology - the role of resistance in plant-insect mutualisms

    Författare :Daniela Weber; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : 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.

  5. 20. Biological control of diamondback moth : the roles of predators, parasitoids and insecticides

    Författare :Freddy Miranda; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : The diamondback moth Plutella xylostella L. (Lepidoptera: Plutellidae) is a serious pest of economically important crucifer crops such as cabbage. The moth has developed resistance to all tested insecticides and further studies on the potential role of factors affecting P. xylostella survival, including natural enemies, are urgently needed.
