This book achieves an invaluable, contemporary picture of the phylum as a whole - Derek Wakelin - Parasitology
This book is mainly directed towards postgraduate students and
professionals in the field of research and implementation of
integrated pest and disease management programmes in greenhouse
crops. After presenting the major pests and diseases that affect
greenhouse vegetable and ornamental crops, several chapters deal
with the tools for designing and implementing IP&DM in
protected cultivation with particular emphasis on biological
control. Current implementation and the future of IP&DM in the
most important protected crops world-wide are presented in the
concluding chapters. Protected cultivation is practised in many
hundreds of thousands of hectares throughout the world under quite
different social, economic and technical conditions. Contributions
to the book reflect such a diversity of situations: from the
high-technology glasshouses of northern Europe and America to the
simple plastic tunnels of the Mediterranean area and temperate
eastern Asia. Furthermore, the editors have entrusted each chapter
to authors whose activity and perspectives could be complementary:
pathologists and entomologists, from private and public sectors,
and from differentiated geographical regions. Probably no book
published to date has offered such a diverse yet integrated
approach to pest and disease control in greenhouse crops. The book
originated from an international course taught at the International
Centre for Advanced Mediterranean Agronomic Studies in Zaragoza,
Spain. The authors are specialists from universities, research
institutions and companies in Europe, America, Asia, Africa and
Oceania.
Volumes I and II of this world catalogue of dragon flies provide a
survey about the system of the group, their geographic distribution
and the most important specific literature. In this catalogue, taxa
are methodized on supraspecific level, below which specific and
intraspecific taxa are presented in alphabetical order.
Proceedings of the 6th International Symposium on Insect-Plant
Relationships (Pau 1986)
The 2nd International Symposium on Trichoptera was held at the
University of Reading, England, 25-29 July 1977. It attracted 68
participants from 22 countries, which was a gratifying response to
the circulation of about 250 workers on caddis flies. It was H.
MALICKY who appreciated the need for a specialized meeting of this
kind and organized the 1st International Symposium on Trichoptera,
which was held at Lunz am See, Austria, 16-20 September 1974. This
volume of Proceedings includes 38 papers; all except one were
presented and discussed in the sessions listed in the programme.
The papers were given in a lecture theatre of the Palmer Building,
and demonstrations were laid out in a laboratory of the Department
of Zoology where members met for their mprning and afternoon
breaks. Members were accommodated in St Patrick's Hall, one of the
University Halls of Residence. They were the guests of the
University at an informal reception on 25 July. On the afternoon of
27 July an excursion was made to the River Lambourn at Bagnor near
NeWbUry. This chalk stream has been the subject of an ecological
study by a team from the Department of Zoology since 1970. The
excursion was also an opportunity to see something of the local
caddis fauna, and to do some collecting. The final session on 29
July, under the chairmanship of G. B. WIGGINS, was followed by a
discussion on future plans."
The papers in this volume have been grouped according to the main
sub-themes of the congress and primarily deal with the biodiversity
issues of invasive crustacea, ecology and behaviour and fisheries
and aquaculture.
Acridids (grasshoppers and locusts) can range from being rare
curiosities to abundant menaces. Some are threatened with
extinction and become subjects of intensive conservation efforts,
while others are devastating pests and become the objects of
massive control programmes. Even within a species, there are times
when the animal is so abundant that its crushed masses cause the
wheels of trains to skid (the Rocky Mountain grasshopper,
Melanoplus spretus Walsh in western North America in the 1860s and
I 870s), while at other times the animal is alarmingly scarce (the
Rocky Mountain grasshopper went extinct in the early 1900s). Why
are there these extremes in one insect family, and even in a single
species? The NATO workshop examined this paradox and its
implications for Environmental Security, which must address both
the elements of land use (agricultural production and pest
management) and conservation of biodiversity. The reconciliation of
these objectives clearly demands a critical assessment of current
knowledge and policies, identification of future research, and
close working relationships among scientists. Insects can present
two clear faces, as well as the intervening gradation. These
extremes require us to respond in two ways: conservation of scarce
species and suppression of abundant (harmful) species. But perhaps
most important, these opposite poles also provide the opportunity
for an exchange of information and insight.
The behaviour of these bees has been adapted to some extent to meet
beekeeping requirements but few advances have been made in altering
their behaviour so that honey and wax production is increased. Bee
pheromone research aims to identify the pheromones and make
analogous synthetic chemicals thus allowing the control of the
colony's activities and enhancing honey production. This book
evaluates the present state of knowledge of each known pheromone,
discusses the pheromones of the stingless bees and describes the
effect of pheromones on the social organization and mating
behaviour of bumblebees. Suggestions are made for further and
different types of research into pheromones. The book should be of
interest to zoologists, entomologists and general biologists.
Initially, this work was designed to document and study the
diversification of modern mammalian groups and was quite successful
and satisfying. However, as field and laboratory work continued,
there began to develop a suspicion that not all of the Eocene story
was being told. It became apparent that most fossil samples,
especially those from the American West, were derived from similar
preservational circumstances and similar depositional settings. A
program was initiated to look for other potential sources of fossil
samples, either from non-traditional lithologies or from geographic
areas that were not typically sampled. As this program of research
grew it began to demonstrate that different lithologies and
different geographic areas told different stories from those that
had been developed based on more typical faunal assemblages. This
book is conceived as an introduction to non-traditional Eocene
fossils samples, and as a place to document and discuss features of
these fossil assemblages that are rare or that come from rarely
represented habitats.
Fruit flies (Diptera: Tephritidae) are among the most destructive agricultural pests in the world, eating their way through acres and acres of citrus and other fruits at an alarming rate and forcing food and agriculture agencies to spend millions of dollars in control and management measures. But until now, the study of fruit flies has been traditionally biased towards applied aspects (e.g., management, monitoring, and mass rearing)-understandable, given the tremendous economic impact of this species. This work is the first that comprehensively addresses the study of the phylogeny and the evolution of fruit fly behavior. An international group of highly renowned scientists review the current state of knowledge and include considerable new findings on various aspects of fruit fly behavior, phylogeny and related subjects. In the past, the topics of phylogeny and evolution of behavior were barely addressed, and when so, often superficially. Fruit Flies (Tephritidae): Phylogeny and Evolution of Behavior is a definitive treatment, covering all behaviors in a broad range of tephritids. This volume is divided into eight sections:
When Franklin published her book on cyst nematodes in 1951, the
cyst nematodes were already known as serious pests of brassicas,
cereals, potatoes and sugar beets. However, at that time this group
of nematode, with about 12 species, was considered tobe largely
temperate in distribu tion. Now a total of 105 species (including
those that are considered as synonyms or species inquirende by some
or all) within six genera of cyst nematodes have been described
from temperate, tropical, and subtropical regions and at least five
species are important constraints to crop produc tion in tropical
agriculture. The previous impression of localization of cyst
nematodes in the temperate region was seemingly an artifact due to
a greater concentration of nematologists in the temperate regions.
Based on my own experience of working in several Asian and African
countries, I believe that many more undescribed species are present
in the tropical countries of Asia and Africa, and probably in other
tropical regions. Most growers, extension workers, and research
managers in these regions are still not aware of the possible harm
of presence of these nematodes in their agricultural soils. The
cyst nematodes are perhaps smaller than the smallest available
computer chip but they are very well programmed to survive and pro
pagate despite severe hardships. These nematodes are very selective
in their choice of food; about 50% of known species are parasites
of plants mainly in the families Poaceae and Fabaceae."
This volume of the Subcellular Biochemistry series is the result of
the long-standing research interest of the editor in the molecular
mechanism underlying Alzheimer's disease and other amyloid
diseases, indicated also by the earlier book in the series (Volume
38), devoted to Alzheimer's disease. The broad coverage within the
present amyloidogenesis book represents an attempt to collate
current knowledge relating to the proteins and peptides involved in
most of the known amyloid diseases, together with some
amyloid/fibril-forming proteins and peptides that are not involved
in diseases. Thus, the range of topics included is comprehensive
and furthermore it was thought appropriate to include both basic
science and clinical presentation of the subjects under discussion.
In aquatic ecosystems, the oligochaetes are often a major component
of the community. Their relevance in sediment quality assessment is
largely related to their benthic and detritivorous life habit. In
this book, we aim to present the state of the art of Pollution
Biology using oligochaete worms in laboratory and field studies.
Future research will require the combination of a variety of
methodological approaches and the integration of the resulting
information, avoiding fragmented and often conflicting visions of
the relationships of the species with their environment. Current
approaches to ecotoxicology and bioaccumulation using ecological
risk assessment provide the opportunity to relate community studies
with probability of effects. This book addresses three main themes:
Ecological and Field Studies using the composition and structure of
oligochaete communities, Toxicology and Laboratory Studies, and
Bioaccumulation and Trophic Transfer Studies. Two appendices list
values of toxicological parameters (LC50, EC50) and several
bioaccumulation variables (bioaccumulation factors, biological
half-life, toxicokinetic coefficients, and critical body residues)
for different oligochaete species. Additional information is
provided on Methodological Issues and on the Taxonomy of several
oligochaete families, with information on the most recent taxonomic
debates. Each chapter includes a critical view, based on the
authors experience, of a number of current issues which have been
raised in the literature.
"Handbook of Agricultural Entomology" by Helmut van Emden is a
landmark publication for students and practitioners of entomology
applied to agriculture and horticulture. It can be used as a
reference and as a general textbook.
The book opens with a general introduction to entomology and
includes coverage of the major insects (and mites) that cause harm
to crops, livestock and humans. The important beneficial species
are also included. Organisms are described in a classification of
insect Orders and Families. The emphasis is on morphological
characters of major taxonomic divisions, "spot characters" for the
recognition of Families, and the life histories, damage symptoms
and economic importance of the various pest species.
The book is beautifully illustrated in full colour with more
than 400 figures showing both the organisms and the damage caused
to plants with diagnostic characters indicated by arrows. Coverage
is world-wide and includes much material stemming from the vast
personal experience of the author.A companion website with
additional resources is available at

This is the long, catalog/marketing description of the product.It's
often said that everyone goes through a "bug phase" -- typically
during childhood -- when they develop an immense interest in
insects and other invertebrates. Given the astounding diversity of
these life forms, it can be overwhelming for those looking to learn
more about their identification features and fascinating lives. The
12-panel folding pocket guide Bugs & Slugs is the perfect
educational tool for those looking to cut through the clutter and
get acquainted with 140 common species of beetles, bugs, flies,
aquatic insects, and spiders. It includes representatives from the
eight major groups of insects, many different types on non-insect
invertebrates, and tips for identifying species. Laminated for
durability, this rich collection is a portable and handy companion
for educators, learners, naturalists, and "bug" enthusiasts in the
midst of their "bug phase" or keen to return to it. Made in the
USA.
This book provides the first monograph of Coccinellidae. Although
the group finds inclusion both in Clausen's (1940) "Entomophagous
Insects" and in Balduf's (1935) "Entomophagous Coleoptera",
reference in these works is limited to three and twenty pages
respectively. Moreover, the last thirty years since these books
appeared have ~een a great deal of work on the group. The use of
insecticides largely destroyed the early attempts at biological
control and interest remained low for as long as insecticides
appeared quite successfuL However, the problems of insecticides
soon became apparent, and in the last decade there have been
tremendous developments in biological control, particularly in
eombin
Proceedings of the 2nd Symposium held at Zvikovske podhradi,
September 2-8, 1984
This volume deals mainly with the biology of the American
cockroach, Periplaneta americana (1.). Contributors were urged to
emphasize recent findings, including unpublished data when
possible, a goal that would not have been feasible if it were not
for the two previously published books on the basic biology of
cockroaches, The Biology o/the Cockroach (1968) by D. M. Guthrie
and A. R. Tindall and The Cockroach, Volume 1 (1968) by P. B.
Cornwell. Those topics not included in The American Cockroach, such
as external morphology, are well covered in the two preceding
books. In addition, these books provided a broad background upon
which contributors to The American Cockroach have been able to
build with recent trends, new and established concepts and
integration. Although this book deals primarily with the American
cockroach, many chapters offer a comparative approach in sections
where the more recent and exciting research has been accomplished
on other species. Most contributors place the cockroach in
perspective with regard to its appropriateness or inappropriateness
for various types of biological investigations. Many questions are
realistically left unanswered when no acceptable or obvious
solution is apparent; an invitation to new researchers to consider
the cockroach as an experimental subject.
Few branches of the biological sciences have developed to such an
extent as has ecology in the recent decades. The successful
development of this science is directly related to need to create a
sound scientific basis by which we can control our diminishing
natural resources and integrate this with the control of biological
systems of the component species. Studies on the bioenergetics of
ecosystems, as well as on the home ostatic mechanisms functioning
at the populations and biocenoses levels are of great importance in
this respect. The results of these studies are very significant in
forestry management which deals with multiannual tree communities -
forest stands. It is particularly important in this of the
necessity for the possible respect for economic planning, in view
prolonged maintenance of forest biocenoses as stable systems.
Neither in the present nor in the immediate future can be
protection of forest ecosystems consisting of natural plant and
animal communities be achieved by the cultivation of resistant
forms or the intensification of chemical intervention."
