    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 effect of tri-ortho-cresylphosphate (TOCP) on poisoning by parathion and paraoxon in susceptible and resistant houseflies (Musca domestica L.) was investigated.

TOCP influenced the penetration of parathion and paraoxon, and this could explain the contradictory results of both an antagonistic and synergistic effect of TOCP on parathion and paraoxon poisoning, described in the literature.

Studies were also carried out on inhibition of cholinesterase (ChE) and aliesterase (AliE) from susceptible and resistant houseflies by TOCP, parathion or paraoxon in vivo and in vitro.

TOCP proved to be a poor ChE inhibitor, but 50 % of AliE in susceptible and 15 % in resistant houseflies were inhibited by this compound.

It was concluded that at least 2 aliesterases were present in houseflies, one sensitive to inhibition by organophosphorus compounds, and the other one almost insensitive. In vitro TOCP protected ChE against inhibition by parathion or paraoxon.

The importance of these findings for the explanation of resistance to organophosphorus compounds in insects was extensively discussed. It was concluded that penetration was an important factor in resistance of houseflies to parathion and paraoxon.
