Phytochemical responses to herbicide exposure and effects on herbivorous insects

Preface

The project presented in this report was carried out in the period from 1996 to 2000 as a collaborative work involving both The National Environmental Research Institute, Department of Terrestrial Ecology and The Royal Veterinary and Agricultural University, Chemistry Department.

The report consists of a summary in both Danish and English, an introductory chapter that presents the background and the scope of the report, a range of chapters presenting the experimental data and finally the results are discussed.

Two master students (Kristine Krogh and Annette Salomonsen) have written their thesis in connection with the project. Dr. Gerard A. J. M. Jagers op Akkerhuis took part in designing the experiment of Chapter 9. Their contribution is appreciated.

Results from the project has have been presented at the Tenth International Symposium on Insect-Plant Relationships in Oxford 4-10 July 1998 and at a research seminar organised by the Danish Environmental Protection Agency on May 28 1998 in Copenhagen.

We are indebted to the following persons, which in the course of the project skilfully carried out experiments and chemical analyses: Inge Lise Lauridsen, Inger Møller, Thomas Seigert, Dana Tvermoes, Celestin Gnahore.

We would also like to thank Bodil Thestrup and Lene B. Bødskov for taking care of many tasks concerning project accounting etc. and for work on the layout of the report.

The project was overseen by a steering committee. The members have made valuable contributions to the project. The committee consisted of:

Inge Vibeke Hansen, Environmental Protection Agency (chairman in the period between January 1996 and July 2000).

Claus Hansen, Environmental Protection Agency (joined the committee as Chairman in July 2000).

Thomas Secher Jensen, The Natural History Museum, Aarhus.

Jens Kvist Nielsen, The Royal Veterinary and Agricultural University, Chemistry Department.
