Manuscript Preparation

General: Manuscripts must be typewritten, double-spaced with wide margins on one side of white paper. Good quality printouts with a font size of 12 or 10 pt are required. The corresponding author should be identified (include telephone, fax number and E-mail address). Full postal addresses must be given for all co-authors. Authors should consult a recent issue of the journal for style if possible. An electronic copy of the paper should accompany the final version. The Editors reserve the right to adjust style to certain standards of uniformity. Authors should retain a copy of their manuscript since we cannot accept responsibility for damage or loss of papers. Original manuscripts are discarded one month after publication unless the Publisher is asked to return

Text: Follow this order when typing manuscripts: Title, Authors, Affiliations, Abstract, Keywords, Main text, Acknowledgements, Appendix, References, Illustrations, Figure Captions and then Tables. Do not import the Figures or Tables into your text. The corresponding author should be identified with an asterisk and footnote. All other footnotes (except for table footnotes) should be identified with superscript Arabic numbers.

Only standard abbreviations should be used. Subject specific abbreviations and jargon will not be accepted.

The Latin names should be given for all species used in the investigation, although taxonomic affiliation and authority need not be provided in the title.

Sequences should be accompanied by an accession number.

Abstracts: This should be a brief summary of the contents and conclusions of the paper, and should not be longer than 200 words and should not contain references.

Keywords: No more than five key word entries should be provided for rapid scanning of the contents of the paper and for compiling the index.

Introduction: This should contain a brief survey of the relevant literature and the reasons for doing the work.

Materials and Methods: Sufficient information should be given to permit repetition of the experimental work. The technical description of methods should be given only when such methods are new.

Results: These should be presented concisely. Only in exceptional cases will it be permissible to present the same set of results in both table and a figure. The results section should not be used for discussion.

Discussion: This should be separate from the results section and should deal with the significance of the results and their relationship to the object of the work.

References: All publications cited in the text should be presented in a list of references following the text of the manuscript. In the text refer to the author's name (without initials) and year of publication (e.g. "Since Peterson (1993) has shown that ...." or "This is in agreement with results obtained later (Kramer, 1994)". For three or more authors use the first author followed by "et al.", in the text. The list of references should be arranged alphabetically by authors' names. The manuscript should be carefully checked to ensure that the spelling of authors' names and dates are exactly the same in the text as in the reference list.

References should be given in the following form:

Slama, K., Coquillaud, M.S. 1992. Homeostatic control of respiratory metabolism in beetles. Journal of Insect Physiology. 38, 783-791.

Saunders, D.S., 1982. Insect clocks, 2nd edn. Pergamon Press, Oxford.

Pichon, Y., Ashcroft, F.M., 1985. Nerve and muscle: electrical activity. In: Kerkut, G.A., Gilbert, L.I. (Eds.), Comprehensive insect physiology, biochemistry and pharmacology, Vol. 5. Pergamon Press, Oxford, pp. 85-113.

References to papers "in press" must mean that the article has been accepted for publication.

References to "personal communications" and unpublished work are permitted in the text only; references to papers in preparation or submitted are not permissible.

Illustrations: All illustrations should be provided in camera-ready form, suitable for reproduction (which may include reduction) without retouching. Photographs, charts and diagrams are all to be referred to as "Figure(s)" and should be numbered consecutively in the order to which they are referred. They should accompany the manuscript, but should not be included within the text. All illustrations should be clearly marked on the back with the figure number and the author's name. All figures are to have a caption. Captions should be supplied on a separate sheet.

Line Drawings: Good quality printouts on white paper produced in black ink are required. All lettering, graph lines and points on graphs should be sufficiently large and bold to permit reproduction when the diagram has been reduced to a size suitable for inclusion in the journal. Dye-line prints or photocopies are not suitable for reproduction. Do not use any type of shading on computer-generated illustrations.

Photographs: Original photographs must be supplied as they are to be reproduced (e.g. black and white or colour). If necessary, a scale should be marked on the photograph. Please note that photocopies of photographs are not acceptable.

Colour: Authors will be charged for reproduction of full colour illustrations as follows: Dfl 800 for the first page, Dfl 400 for subsequent pages. Per year the Editors will award 12 articles with one page of free colour illustrations.

Tables: Tables should be numbered consecutively and given a suitable caption and each table typed on a separate sheet. Footnotes to tables should be typed below the table and should be referred to by superscript lowercase letters. No vertical rules should be used. Tables should not duplicate results presented elsewhere in the manuscript, (e.g. in graphs). Units of measure should always be indicated clearly.
