    Union Catalogue of Agricultural Libraries in the Netherlands

    The WUR Library Catalogue contains bibliographic data on books and periodicals held by the libraries of Wageningen University and Research Centre and some 15 associated libraries. Holding data are added to each record.

    Subjects covered include Agrotechnology, Food and Food Production, Plant and Animal Sciences, Soil Science, Geo-information, Landscape and Spatial Planning, Water and Climate, Ecosystem Studies, Economics and Society.

    The joint collections of the participating libraries cover a substantial part of the internationally available scientific literature in these disciplines.

    As far as Dutch scientific literature in these fields is concerned, coverage can be considered near 100%, including much of the so-called "grey literature".

    All titles are entered in their original language. Keywords are added to facilitate subject searching.

    The database is updated every day and now contains over 830.000 records.

The extensive literature concerning leafroll virus, virus Y and their vector Myzus persicae Sulz. was surveyed. The relations between virus, aphid and plant were discussed. In virus spread, endogenous infection (spread of virus within the field whereby virus diseased plants act as sources of infection) was distinguished from exogenous infection (virus introduced in the crop from outside by winged aphids). The main object of field experiments in seven years was to check the spread of virus in potato crops by spraying systemic aphicides. This vector control eliminated endogenous leafroll infection entirely.

The exogenous infection, was mostly far less extensive and was partially eliminated. Prevention by vector control of the spread of virus Y in potato crops gave varying results.

Endogenous infection by wingless aphids could indeed be eliminated entirely.

The endogenous and exogenous infections, sometimes so important, often mainly caused by winged non-potato aphids, when making their feeding punctures on the host plant without colonizing it, was however only partially eliminated. Yet vector control with aphicides was successful where in a crop virus-diseased plants occurred, which showed the symptoms of infection only after a considerable time.
