Neurochemical Techniques in Insect Research properly emphasizes the
insect. It only scratches the surface of the exploding repertoire
of general neuro chemical techniques that can be applied to insect
research in 1985. But it al so presents the advantages of using
insects for studying certain biological questions that are
approachable by neurochemical techniques. Even more so, it
summarizes the long list of unique problems encountered in
attempting to study insects by neurochemical techniques. As in
other volumes of this series, the contributors to this volume are
the authorities in the field. They themselves have developed much
of the material presented. Thus the sum effort provides a true
description of the state of the art; and, pleasantly, it does so in
a very complete and clear manner. Readers of this series will not
need to be reminded that, despite the fact that vertebrates make up
only about 3% of all animal species, research in in vertebrates
such as insects has lagged behind that on vertebrates, at least in
the neurochemistry area; the relative simplicity and large cell
size of the in sect nervous system has always provided incentive
for work in neurophysiol ogy and neuroanatomy. Toxicology interests
will always stimulate a certain amount of work on insect
neuropharmacology, and insects are extremely suitable for several
areas of toxin research. Last but not least, the insects are
beautiful organisms for which the applications of genetics can be
made to the study of nervous system function."
Insects as a group occupy a middle ground in the biosphere between
bacteria and viruses at one extreme, amphibians and mammals at the
other. The size and general nature of insects present special
problems to the student of entomology. For example, many
commercially available instruments are geared to measure in grams,
while the forces commonly encountered in stUdying insects are in
the milligram range. Therefore, techniques developed in the study
of insects or in those fields concerned with the control of insect
pests are often unique. Methods for measuring things are common to
all sciences. Advances sometimes depend more on how something was
done than on what was measured; indeed a given field often
progresses from one technique to another as new methods are
discovered, developed, and modified. Just as often, some of these
techniques find their way into the classroom when the problems
involved have been sufficiently ironed out to permit students to
master the manipulations in a few laboratory periods. Many
specialized techniques are confined to one specific research
laboratory. Although methods may be considered commonplace where
they are used, in another context even the simplest procedures may
save considerable time. It is the purpose of this series (1) to
report new developments in methodology, (2) to reveal sources of
groups who have dealt with and solved particular entomological
problems, and (3) to describe experiments which may be applicable
for use in biology laboratory courses.
Most neurobiological research is performed on vertebrates, and it
is only natural that most texts describing neuroanatomical methods
refer almost exclusively to this Phylum. Nevertheless, in recent
years insects have been studied intensively and are becoming even
more popular in some areas of research. They have advantages over
vertebrates with respect to studying genetics of neuronal
development and with respect to studying many aspects of
integration by uniquely identifiable nerve cells. Insect central
nervous system is characterized by its compactness and the rather
large number of nerve cells in a structure so small. But despite
their size, parts of the insect eNS bear structural comparisons
with parts of vertebrate eNS. This applies particularly to the
organization of the thoracic ganglia (and spinal cord), to the
insect and vertebrate visual sys tems and, possibly, to parts of
the olfactory neuropils. The neurons that make up these areas in
insects are often large enough to be impaled by microelectrodes and
can be injected with dyes. Added to advantages of using a small
eNS, into which the sensory periphery is precisely mapped, are the
many aspects of insect behaviour whose components can be quan
titized and which may find both structural and functional
correlates within clearly defined regions of neuropil. Together,
these various features make the insect eNS a rewarding object for
study. This volume is the first of two that describe both classic
and recent methods for neuroanatomical research on insect eNS."

Due to the worldwide importance of rice as a crop plant, the
biology of rice pests is of great interest to agricultural
research. This timely book brings together contributions from the
fields of entomology, agronomy, population ecology, and
biostatistics to provide a comprehensive survey of rice-insect
interaction. Among the topics discussed are - crop loss assessment
- economic thresholds and injury levels for incest pests - mosquito
leafhoppers and planthoppers population dynamics - pheromone
utilization - techniques for predator evaluation - chemical based
for insect resistance - applications of tissue culture - systems
analysis and - rice pestmanagement. With its emphasis on
experimental techniques of pest analysis and control, Rice Insects:
Management Strategies will be a valuable reference for researchers
and practitioners alike.
