  2. 6. 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

  4. 7. Bed filters for phosphorus removal in on-site wastewater treatment : Removal mechanisms and sustainability

    Author : David Eveborn; Jon Petter Gustafsson; Gunno Renman; Erik Kärrman; Lars Lövgren; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; On-site wastewater treatment; Eutrophication; Environmental impact assessment; Phosphorus removal mechanisms; Soil infiltration; Reactive bed filters; Environmental engineering; Miljöteknik; Water engineering; Vattenteknik; Soil chemistry; Markkemi;

    Abstract : For many surface waters, phosphorus (P) leaching is a serious problem that should be minimized to prevent eutrophication. In Sweden there is a demand for physical and technical development of high-performance P removal techniques to reduce phosphorus leaching from on-site wastewater treatment systems to the Baltic Sea.

    Abstract : Norway spruce [Picea abies (L.) Karst.] is a main tree species in European forests and is important both ecologically and economically. The root rot fungus Heterobasidion annosum sensu lato (s. READ MORE

  6. 9. Genomic variation and molecular mechanisms of the host response to gastrointestinal nematodes in small ruminants

    Author : Hadeer Moursy Aboshady; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : Gastrointestinal nematode (GIN) infections are one of the major constrains for sheep and goat production worldwide. One of the promising control strategies is the genetic selection for resistant animals as there are no issues due to anthelmintic resistance and it aligns to demands for chemical-free food.
