    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.

Sections of the text are on the systematics and the fully illustrated morphology of the species (with description of N. dalbergiae n.sp.), postembryonic development of the individuals, formation of the soldier caste, details of swarming habits, sex attraction, and foundation of new colonies (in old snags at some height in standing trees), method of estimating the approximate age of the colonies, factors controlling the appearance of sexuals, peculiar 2nd instar larva with thoracic lobes in mature colonies (still unexplained), advanced habit of using excrement for such purposes as building. Graphs show the course of development of the colonies during the first 21 years (in artificial nests and in the forest), the rapid growth to about the 6th year (top size 2800 individuals), and the ensuing natural decline. Twenty plates with 50 illustrations cover the outward appearance of infested trunks, devices for caging nests on trees or severed from the trunk and placed in the open; cross sections of infested portions, breeding experiments in specially constructed artificial nests, the 7 larval and nymphal stages, soldiers of different size and their pseudonymphs, neoteinics, a complete incipient colony, method of trapping sexuals, experiments on the radius of flight, predators and inquilines.

* The species has since been classified as Neotermes tectonae Damm.
