    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.

For practical control, a study was made of Scirpophaga innotata Wlk., a noxious rice stalk borer in certain regions of Java.

Caterpillars normally developed and pupated in stalks that had not reached the stage of ear formation. In paddy from before flowering, however, caterpillars entered into a resting stage (diapause), induced by food rich in carbohydrates and proteins.

After harvest diapausing caterpillars remained in the stubble. Further development started after at least 3 months diapause and the stubble and the soil were wetted. This was usually with the first heavy rainfall in the west monsoon. The longer the diapause the sooner moths appeared; with a 3 months' diapause moths emerged 80 days after rainfall began, with a 6 months' diapause after a mean of 33 days.

The cultural practice of timed rice sowing was introduced. Sowing started not earlier than one month after the first rains had fallen. Thus infestation of the young fields was prevented for the greater part.
