  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. Quantity and quality of oaks (Quercus) as suitable habitats for the longhorn beetle species Plagionotus detritus : An inventory study in Stockholm and Uppsala County, Sweden

    Master-uppsats, Uppsala universitet/Institutionen för biologisk grundutbildning

    Författare :Ida Widegren; [2023]
    Nyckelord :Plagionotus detritus; P. detritus; Cerambycidae; Cerambycinae; longhorn beetle; insects; habitat; oak; Quercus; conservation; ecology; endangered; threatened;

    Sammanfattning : The longhorn beetle Plagionotus detritus is associated with newly dead oak wood and is declining throughout its distribution range. In Sweden, P.detritus has displayed one of the most dramatic reductions in distribution recorded for insect species and is near regional extinction. LÄS MER

  4. 3. Biologisk framställning av insektsferomon med enzymer från japansk feberbuske

    Kandidat-uppsats, SLU/Dept. of Plant Breeding (from 130101)

    Författare :Felicia Edman; [2022]
    Nyckelord :Lindera obtusiloba; DGAT; PDAT; ovanliga fettsyror; fettsyrasyntes; transformation; Gateway-kloning; råolja;

    Sammanfattning : Sedan klimatförändringarna fått större plats i dagens forskning har även kraven på förbättrade metoder i vår livsmedelsförsörjning ökat. Feromonfällor är idag en välkänd och uppskattad metod för att undvika användning av farliga insekticider. LÄS MER

  5. 4. Can Saccharomycopsis vini and Z4-11Al be used in a push-pull system against the invasive pest Drosophila suzukii?

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

    Författare :Hedda Andersson; [2022]
    Nyckelord : Z -4-undecenal; pheromone; yeast; volatiles; pest management; spotted wing drosophila;

    Sammanfattning : Drosophila suzukii is a pest with global spread that lays its eggs in soft fruits. It has been deemed potentially invasive to Sweden. Contrary to other Drosophila species, D. suzukii possess a serrated ovipositor which makes it possible for it to lay its eggs in ripening fruits. LÄS MER

  7. 5. Training dogs to indicate synthetic pheromones from Plagionotus detritus, Coleoptera, Cerambycidae to detect living beetles

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

    Författare :Matilda Apelqvist; [2022]
    Nyckelord :Detection dog; indicate synthetic pheromone; coleoptera; conservation biology; endangered species;

    Sammanfattning : Using dogs to detect insects’ emitted volatiles is a non-invasive procedure, and a trained detection dog is potentially a fast and accurate method to search for saproxylic insects. The longhorn beetle Plagionotus detritus is categorized as Endangered in the Swedish Red List of Threatened Species. LÄS MER
