  3. 2. What is the view of the black coffee twig borer (Xylosandrus compactus (Eichhoff)) among farmers, advisers and experts, and is the infestation on robusta coffee trees (Coffea canephora) higher or lower when grown close to a Ficus natalensis?

    Kandidat-uppsats, SLU/Dept. of Ecology

    Författare :Julia Dahlqvist; [2016]
    Nyckelord :Xylosandrus compactus; black coffee twig borer; robusta coffee; Coffea canephora; Uganda; Ficus natalensis; Natal fig;

    Sammanfattning : The coffee industry in Uganda employs over 3.5 million families, and the exportation of coffee generates about 20 % of the foreign exchange earnings. Over the course of the past two decades a pest called the Black Coffee Twig Borer, Xylosandrus compactus (Eichhoff), has invaded the coffee plots. LÄS MER

  5. 4. The effect of non-host plant volatiles on the reproductive behaviour of the Egyptian cotton leafworm, Spodoptera littoralis

    Master-uppsats, SLU/Dept. of People and Society

    Författare :Altaf Hussain; [2012]
    Nyckelord :Adhatoda vasica; electrophysiology; Justicia adhatoda; Lepidoptera; Noctuidae; non-host plants; reproductive behaviour; semiochemical diversity; socioeconomics; Spodoptera littoralis; spruce;

    Sammanfattning : Spodoptera littoralis is a major pest of cotton in Egypt, causing serious economic losses. Egyptian farmers highly appreciate biological control of the pest as synthetic pesticides are very unsustainable. Phytophagous insects rely on plant volatiles to locate oviposition, feeding and, mating sites. We tested newly emerged S. LÄS MER

  7. 5. Effect of patch heterogeneity on oviposition in two lepidopteran Brassica pests

    Kandidat-uppsats, SLU/Dept. of Ecology
