This volume contains the proceedings of the Third International
Conference on Insect Neurochemistry and Neurophysiology (ICINN'89),
which was held at the University of Maryland at College Park, Maryland,
on July 10-12, 1989. The ICINN meetings were ini- tiated in 1983 at a
time when insect neurobiology was emerging as a vigorous sector of
entomology, requiring a degree of attention and autonomy long before
granted to its sister field, vertebrate neurobiol- ogy. The distinctly
medical aspects of the latter were replaced by potentiali ties for
developing new approaches to insect control, and the difference was
reflected in the kind of sponsorship that has made the ICINNs possible.
It is to the credit of the sponsors of the present con- ference, i. e.,
Agricultural Research Service, US Department of Agri- culture, American
Cyanamid, BASF, Dow Chemical USA, E. I. DuPont de Nemours, Monsanto,
Nippon Soda, Rohm and Haas, and Sandoz Crop Protection, that they
recognized the need for providing a forum for specialized scientific
presentations as well as a medium by which ideas and information could
be exchanged directly and cooperation could be planned. As in the
previous conferences in 1983 and 1986, the ICINN'89 program contained
state-of-the-art plenary lectures or reviews by invited speakers as well
as shorter research communications pre- sented orally or as posters. The
latter two are included here in three sections: neuroanatomy,
neurochemistry, and neurophysiology.
