    Abstract : Den intensifiering av jordbruket som pågått under de senaste decennierna har lett till en förlust av biodiversitet i jordbrukslandskapet, bland annat till följd av att andelen naturliga habitat minskar. En förlust av biodiversitet innebär också en förlust av de ekosystemtjänster vi kan få från olika nyttodjur, såsom naturlig biologisk bekämpning, pollinering och ogräsfröpredation. READ MORE

    Keywords : natural pest control; natural enemies; landscapes; agricultural diversification; pesticide reduction; mapping; ecosystem service; ecological intensification; agroecology;

    Abstract : Natural pest control describes the process of natural enemies suppressing pests and thus reducing crop damage and stabilizing yields. How well these beneficial arthropod predators and parasitoids can thrive in a landscape is influenced by the land-use types in the vicinity, such as forest patches, pastures, or agricultural fields, and their ability to provide resources.
