  2. 16. Evaluation of plant resistance in field pea by host plant choice behaviour of pea weevil (Bruchus pisorum L.) : implications for pest management

    Author : Esayas Mendesil; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : Field pea (Pisum sativum L.) is an important grain legume crop due to its nutritional value and role in improving soil fertility in cropping systems. Insect pests are one of the main production constraints for field pea, with pea weevil (PW), (Bruchus pisorum L.) being an economically important pest of field pea worldwide. READ MORE

  4. 17. Natural enemies: Functional aspects of local management in agricultural landscapes

    Author : Helena Hanson; Biodiversitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Agricultural intensification; sustainable agriculture; land use; management intensity; landscape scale; ecosystem services; biological control; species trait; pesticides; predatory arthropods; parasitoids; pollen beetles;

    Abstract : Agricultural intensification has raised the global food production but also caused major concerns about environmental and health effects, including contamination by pesticides. Pesticide applications may induce toxicity not only on the target pest species but especially on non-target species. READ MORE

  5. 18. Food webs in agroecosystems : implications for biological control of insect pests

    Author : Eve Roubinet; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : The management of insect pests in modern agriculture is dominated by chemical control, despite wide recognition of its detrimental impact on the environment and human health. As a sustainable alternative, the service of biological control of insect pests is provided by a diversity of natural enemies, such as ground dwelling carabids and spiders. READ MORE

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

    Author : Guillermo Aguilera Nuñez; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : 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. READ MORE

  7. 20. Biological control of plant-parasitic nematodes by the fungus Clonostachys rosea

    Author : Mudassir Iqbal; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : 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. READ MORE
