This monograph represents the current status of neuro- ethological
research on the diurnal behavior of the stick in- sect, Carausius
morosus. The growing profusion of inter- related studies, many of which
are published only in German, makes an overview of this field
increasingly difficult. Many stick insect results contribute to general
problems like con- trol of catalepsy, control of walking,
program-dependent reactions and control of joint position. For this
reason I decided to compile and synthesize the results that are pre-
sently available even though the analyses are far from con- cluded. In
addition to both published and unpublished results of the group in
Kaiserslautern (Bassler, Cruse, Ebner, Graham, Pfluger, Storrer, as well
as doctoral and masters students), I have drawn upon the literature
which had ap- peared as of summer 1981. This includes above all the work
of Godden and of Wendler and his colleagues in Cologne. A summary of the
anatomical and physiological background, necessary for an understanding
of these investigations, is provided in an appendix (Chap. 6).
Methodological details must be obtained from the original publications.
Figures for which no source is given are from my own studies. I intend
to update this monograph on an annual basis. Requests for these
supplements should be directed to me in Kaiserslautern. I would like to
express my appreciation to all members of the group in Kaiserslautern
for their constructive discussions, their unflagging cooperation, and
their permission to include hitherto unpublished results.
