  1. 1. Pheromone-based mating disruption to control Spodoptera frugiperda in Tanzania: Possibilites and Constraints for smallholders

    Master-uppsats, SLU/Dept. of Biosystems and Technology (from 130101)

    Författare :Thomas O'Malley; [2024]
    Nyckelord :pheromone; mating disruption; fall armyworm; Tanzania; smallholder; Spodeptera frugiperda; integrated pest; management;

    Sammanfattning : Despite a growing interest in the use of pheromones as a more sustainable form of pest control, their use remains unstudied in the smallholder context. This paper is one of the first to study their use by small scale Tanzanian maize farmers to control the invasive pest Spodoptera frugiperda (known as fall armyworm). LÄS MER

  3. 2. Miljöfaktorers påverkan på nettoförflyttning hos mördarsnigel, Arion vulgaris

    Kandidat-uppsats, Karlstads universitet/Institutionen för miljö- och livsvetenskaper (from 2013)

    Författare :Richard Danielsson; [2024]
    Nyckelord :Arion vulgaris; dispersal movement; pit tagging; Arion vulgaris; förflyttning; mördarsnigel; telemetri;

    Sammanfattning : The Spanish slug, Arion vulgaris, is an invasive species in Sweden and the rest of northern Europe, dispersing rapidly and widely and it has become a significant pest for both gardening enthusiasts and commercial farmers. In this study, I examined the relationship between dispersal movements and temperature, relative humidity, illuminance, and individual body mass of the slugs. LÄS MER

  4. 3. How distributional equity affects evolutionarily sustainable landscape management

    Master-uppsats, Göteborgs universitet / Institutionen för biologi och miljövetenskap

    Författare :Malin Johansson; [2023-12-14]
    Nyckelord :;

    Sammanfattning : As the human population rapidly grows, ensuring food availability for everyone will require substantial agricultural intensification in a sustainable manner.

  5. 4. ANALYS OCH IDENTIFIERING AV BEKÄMPNINGSMEDEL I HISTORISKA TEXTILIER

    Kandidat-uppsats, Göteborgs universitet/Institutionen för kulturvård

    Författare :Stina Johansson; [2023-06-15]
    Nyckelord :XRF-analysis; FTIR-analysis; Pesticide Identification; Historical Textiles;

    Sammanfattning : This essay will investigate the risks associated with pesticide contamination in textile collections and how information about pesticide content can be found. Uniforms from the collection of the now closed Gothenburg military museum was analysed using Dosa test strips for chloride content, XRF-analysis and ATR-FTIR analysis. LÄS MER

  7. 5. Exploring patterns in risk factors for bark beetle attack during outbreaks triggered by drought stress with harvester data on attacked trees: A case study in Southeastern Sweden

    Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Nikolaos Kouskoulis; [2023]
    Nyckelord :Geography; GIS; Geographic Information Science; Forest ecosystems; Bark beetle outbreak; Southeastern Sweden; Predisposing factors; Triggering factors; Drought stress; Earth and Environmental Sciences;

    Sammanfattning : ABSTRACT Raising temperatures and climate variability have intensified extreme weather events worldwide. These extremes can enhance and trigger possible pest outbreaks. Bark beetle attacks have become a major concern in regions with extensive spruce forest areas. Southeastern Sweden has faced repeated outbreaks resulting in widespread tree loss. LÄS MER
