    Wageningen PhD theses


    This database contains bibliographic descriptions of all Wageningen University PhD theses from 1920 onwards. It is updated on a daily basis by WUR Library.

    Author abstracts and/or summaries are added to all descriptions. A link to the full text dissertation is added to the bibliographic description. In a few cases, no electronic version is available, mostly because of copyright issues.

    Hard copies of all theses are available for loan at WUR Library. To request them, click the link Request this publication in the full record presentation. This is a fee based service.

Regulation of cucumber (Cucumis sativus) induced defence against the two-spotted spider mite (Tetranychus urticae) [PhD thesis]
He, Jun \ 2016
cucumis sativus - cucumbers - induced resistance - plant pests - tetranychus urticae - mites - defence mechanisms - herbivore induced plant volatiles - herbivory - metabolomics - terpenoids - genomics

Abstract:
This study, using cucumber (Cucumis sativus) and the two-spotted spider mite (Tetranychus urticae) as model, aimed to reveal the molecular mechanisms underlying the induced defence during herbivory, with emphasis on transcriptional changes and the involved TFs, the enzymatic function of the genes associated with volatile biosynthesis, and their promoters which regulate their expression.

Economic impact assessment of invasive plant pests in the European Union [PhD thesis]
Soliman, T. \ 2012
plant pests - plant diseases - plant parasitic nematodes - invasive species - economic impact - assessment - european union

Abstract:
According to the International Plant Protection Convention (IPPC) and the Agreement on the Application of Sanitary and Phytosanitary measures (SPS Agreement) of the World Trade Organization (WTO), phytosanitary measures should be economically justifiable. The economic impact assessments within a pest risk analysis are currently based on a framework with qualitative questions and not on an explicit quantification of costs. Available quantitative methodologies to assess plant health risks, and in particular economic impacts, are currently hardly applied in the assessment of plant health risks for the EU, restricting the economic justification of plant health policies.
