    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.

After discussion of the distribution of the insect and of its taxonomic classification, demonstrating the synonymy of S. hampei (Ferr.) and S. coffeae Haged., an attempt was made to analyse the factors playing a role in the epidemiology of the pest.

Of climatic factors temperature favoured speed of development, slowing it down when the berries ripen and accelerating it after harvest, thus leading to a rapid exhaustion of available food supply. The rainfall distribution determined the growth cycle of the coffee berries and the relative humidity affected the incidence of fungal parasites of the beetle.

The quantity of food available provided for the yearly fluctuations in attack. The suitability of the berries for food depended on their maturity, which could be distinguished by the beetle. Characteristics of the berries provided possible resistance factors.

Of the predators man was the most important. Regular picking prevented the outbreak of an epidemic. The bionomics and importance of a hitherto unknown Bethylid parasite of the beetle, Cephalonomia stephanoderi Betrem, were given. The flight muscle degeneration in the adult female beetle was described.
