Only four short decades ago, the control of insect pests by means
of chemicals was in its early infancy. The pioneers in the area
consisted largely of a group of dedicated applied entomologists
working to the best of their abilities with a very limited arsenal
of chemicals that included inorganics (arsenicals, fluorides,
etc.), some botanicals (nicotine), and a few synthetic organics
(dinitro-o-cresol, organothiocyanates). Much of the early research
was devoted to solving practical problems associated with the
formulation and application of the few existing materials, and
although the discovery of new types of insecticidal chemicals was
undoubtedly a pipe dream in the minds of some, little or no basic
research effort was expended in this direction. The discovery of
the insecticidal properties of DDT by Paul Miiller in 1939 has to
be viewed as the event which marked the birth of modern insecticide
chemistry and which has served as the cornerstone for its subse
quent developement. DDT clearly demonstrated for the first time the
dramatic potential of synthetic organic chemicals for insect
control and provided the initial stimulus which has caused
insecticide chemistry to become a field not only of immense
agricultural and public health importance but also one that has had
remarkable and unforseeable repercussions in broad areas of the
physical, biological, and social sciences. Indeed, there can be few
other synthetic chemicals which will be judged in history to have
had such a broad and telling impact on mankind as has DDT."
Arthropods are invertebrates that constitute over 90% of the animal
kingdom, and their bio-ecology is closely linked with global
functioning and survival. Arthropods play an important role in
maintaining the health of ecosystems, provide livelihoods and
nutrition to human communities, and are important indicators of
environmental change. Yet the population trends of several
arthropods species show them to be in decline. Arthropods
constitute a dominant group with 1.2 million species influencing
earth's biodiversity. Among arthropods, insects are predominant,
with ca. 1 million species and having evolved some 350 million
years ago. Arthropods are closely associated with living and
non-living entities alike, making the ecosystem services they
provide crucially important. In order to be effective, plans for
the conservation of arthropods and ecosystems should include a
mixture of strategies like protecting key habitats and genomic
studies to formulate relevant policies for in situ and ex situ
conservation. This two-volume book focuses on capturing the
essentials of arthropod inventories, biology, and
conservation.Further, it seeks to identify the mechanisms by which
arthropod populations can be sustained in terrestrial and aquatic
ecosystems, and by means of which certain problematic species be
managed without producing harmful environmental side-effects. This
edited compilation includes chapters contributed by over 80
biologists on a wide range of topics embracing the diversity,
distribution, utility and conservation of arthropods and select
groups of insect taxa. More importantly, it describes in detail the
mechanisms of sustaining arthropod ecosystems, services and
populations. It addresses the contribution of modern biological
tools such as molecular and genetic techniques regulating gene
expression, as well as conventional, indigenous practices in
arthropod conservation. The contributors reiterate the importance
of documenting and understanding the biology of arthropods from a
holistic perspective before addressing conservation issues at
large. This book offers a valuable resource for all zoologists,
entomologists, ecologists, conservation biologists, policy makers,
teachers and students interested in the conservation of biological
resources.
Arthropods are one of the most concerning threats in poultry
industries due to both direct and indirect pathogenic effects. One
of the most important arthropods affecting poultry production is in
the genus Dermanyssus (Acari: Dermanyssidae) with Dermanyssus
gallinae (De Geer) the most important (Fletcher and Axtell 1991;
Maurer and Baumga rtner 1992). Dermanyssus gallinae, also known as
'poultry red mite' or 'red mite' is a direct pest

and hatch into six-legged larvae in 2-3 days. The chicken mite is
seldom seen on the birds because of its intermittent feeding at
night but skin lesions (especially on the breast and lower legs)
are evidence of the feeding (Baker 1999).

Machine learning is a novel discipline concerned with the analysis
of large and multiple variables data. It involves computationally
intensive methods, like factor analysis, cluster analysis, and
discriminant analysis. It is currently mainly the domain of
computer scientists, and is already commonly used in social
sciences, marketing research, operational research and applied
sciences. It is virtually unused in clinical research. This is
probably due to the traditional belief of clinicians in clinical
trials where multiple variables are equally balanced by the
randomization process and are not further taken into account. In
contrast, modern computer data files often involve hundreds of
variables like genes and other laboratory values, and
computationally intensive methods are required. This book was
written as a hand-hold presentation accessible to clinicians, and
as a must-read publication for those new to the methods.
This text provides an introductory account of the physiology of
insects, intelligible to any reader with an elementary knowledge of
biology. It should be of interest to undergraduate students of
biology, entomology and agriculture.
This book reviews the latest research on bioproducts from various
economically important insects, such as silkworms, honey bees, lac
and drosophila, and termites, and discusses their general,
biomedical and industrial applications in detail. It includes
chapters focusing on insects as a food source, probiotics,
silk-based biomaterials, insect pheromones, insects as biomedicine
source, pupa oil chemistry, non-protein compounds from Lepidopteran
insects, insect chitin and chitosan, polyphenols and flavonoids.
Model insects like Bombyx mori or bees were domesticated in Asian
countries thousands of years ago. Over time, natural products from
these animals became industrialized and today they attracting
increasing attention thanks to their sustainability and their
manifold applications in agriculture and biomedicine. The book is
intended for entomologists, material scientists, natural product
researchers and biotechnologists.
A survey of the development and practice of butterfly conservation
in south east Australia, tracing evolution of the science through a
series of cases from focus on single subspecies through increasing
levels of ecological complexity to critical biotopes and
communities. The book summarises much previously scattered
information, and provides access to much regional information of
considerable interest to practitioners elsewhere.
Provides new insights into the persistent species "problem."
Focuses on conceptual history and identifies pivotal landmarks in
the history of the concept of species Argues for a scientific
consistency of species pluralism. Discusses the "evolving
species-hood" in the context of new essentialism.
This timely volume presents a comprehensive overview of the
behavioral and physiological mechanisms underlying insect feeding.
The single source for up-to-date information on the subject, it
features contributions from the most authoritative scientists in
the field worldwide. Taking an accessible approach focusing on the
sequential stages of the feeding process, Regulatory Mechanisms in
Insect Feeding explores the principles regulating feeding, and it
offers information necessary for the development of more effective
and environmentally safe methods to control the feeding of pest
insects. The authors incorporate a spectrum of information in areas
ranging from neurophysiology to insect control. An inclusive
reference that reflects recent expansion and advances in the field,
this book considers the problems encountered by insects when
feeding on different types of food, as well as their adaptations
for dealing with the problems introduces the cyclic nature of
feeding activity and its components and provides the framework for
the discussion of various control mechanisms discusses the
underlying regulatory mechanisms of feeding in both the short and
long terms in insects with a diversity of feeding habits
synthesizes concepts and details of the basic mechanisms underlying
insect feeding behavior that are essential for the development of
pest management methods. Regulatory Mechanisms in Insect Feeding is
the ideal text for graduate courses in entomology and zoology with
a special focus on insect behavior, physiology, neurobiology, and
control. It is also a valuable resource for ecologists interested
in insect-plant and insect-animal interactions, for scientists
concerned with the mechanismsbehind the physiology and behavior of
feeding, and for those working in crop protection and pest
management.
While we may have always assumed that insects employ auditory
communication, our understanding of it has been impeded by various
technical challenges. In comparison to the study of an insect's
visual and olfactory expression, research in the area of acoustic
communication has lagged behind. Filling this void, Insect Sounds
and Communication is the first multi-author volume to present a
comprehensive portrait on this elusive subject. The text includes
32 chapters written by top experts from all corners of the globe.
Divided into two major sections, this groundbreaking text starts
with a general introduction to insect sounds and communication that
leads into a discussion of the technical aspects of recording and
analyzing sounds. It then considers the functioning of the sense
organs and sensory systems involved in acoustic behavior, and goes
on to investigate the impact that variables such as body size and
temperature have on insect sounds and vibrations. Several chapters
are devoted to various evolutionary and ecological aspects of
insect communication, and include rare information on
seldom-studied groups, including Neuropterida and Plecoptera. The
second section of the book includes chapters on communication and
song repertoires of a wide diversity of insects, including
Heteroptera, Auchenorrhyncha, Psylloidea, Diptera, Coleoptera, and
Hymenoptera . Insect Sounds and Communication is packaged with a
DVD, which holds sound and video recordings of many of the insects
discussed throughout the text, as well as many full color
illustrations not included in the printed text. The DVD also
features an unabridged discussion in French of the contribution of
the famous French cicadologist, MichelBoulard.
Planthoppers include some of the most devastating pests of major
agricultural crops throughout the world. One species, the rice
brown planthopper, is among the most economically important pests
in Asia. In past decades, government policies encouraged the
control of rice planthoppers with synthetic pesticides, a tactic
which promoted insecticide resistance and often led to the
pesticide-induced resurgence of pest populations. To deter
planthopper outbreaks, a more ecologically sound management
strategy is being implemented, one based on a thorough
investigation of population dynamics, natural enemies, and the
genetics of host plant and insecticide adaptation. In the natural
habitats of North America and Europe, scientists have also used
planthoppers as model organisms to test ecological and evolutionary
theory. The consequence of these diverse studies is an extremely
scattered literature on planthoppers that has never been
synthesized from an ecological perspective. This volume summarizes
what is known about planthopper ecology and biological control. It
takes a theoretical approach yet is deeply concerned with the
application of theory to the practical problems of pest management.
A multi-authored work on the basic biology of Asian honeybees,
written by expert specialists in the field, this book highlights
phylogeny, classification, mitochondrial and nuclear DNA,
biogeography, genetics, physiology, pheromones, nesting,
self-assembly processes, swarming, migration and absconding,
reproduction, ecology, foraging and flight, dance languages,
pollination, diseases/pests, colony defensiveness and natural
enemies, honeybee mites, and interspecific interactions.
Comprehensively covering the widely dispersed literature published
in European as well as Asian-language journals and books,
"Honeybees of Asia" provides an essential foundation for future
research.
Insects are the major component of the world's biodiversity. By
their vast numbers of both species and individuals, they are vital
determinants of the terrestrial ecological processes.
Quantitatively, insects are important pointers for the species-rich
geographical areas. Qualitatively, they are also important, whether
the subjects of conservation themselves or as tools for identifying
biotic areas with high endemism. "Insect Conservation Biology"
covers a wide range of topics from single species to landscape
conservation, and from rare butterflies to the benefits-and-risks
of biocontrol agents. The approach is both positive and realistic,
with insects being discussed in the contexts of sustainable
development, agroecology and monitoring environmental change.
Ethical issues surrounding insects are also considered as well as
preservation technology and restoration ecology. Conservation
circles have given too little attention to the ecological
significance of insects, while entomologists have been employed
mostly to control a tiny minority of species of insect pests. The
realms of conservationist and entomologist are brought together in
this book. This book should be of interest to conservation
managers/biologists, entomologists, ecologists, and environmental
scientists interested in biological diversity.
This volume embraces the history of insect palaeontology, methods
for studying fossils, the taphonomic processes leading to their
formation, the diagnostic features of all insect orders, both
extant and extinct, the major fossils of each order, and the
implications that can be drawn from the palaeoentomological record
about past ecology and climates.
JOHN G. HILDEBRAND Research on insect olfaction is important for at
least two reasons. First, the olfactory systems of insects and
their arthropod kin are experi mentally favourable models for
studies aimed at learning about general principles of olfaction
that apply to vertebrates and invertebrates alike. Detailed
comparisons between the olfactory pathways in vertebrates and
insects have revealed striking similarities of functional
organisation, physiol ogy, and development, suggesting that
olfactory information is processed through neural mechanisms more
similar than different in these evolution arily remote creatures.
Second, insect olfaction itself is important because of the
economic and medical impact of insects that are agricultural pests
and disease vectors, as well as positive impact of beneficial
species, such as the bees and moths responsible for pollination and
production of honey. The harm or benefit attributable to an insect
is a function of what it does - that is, of its behaviour - which
is shaped by sensory information. Often olfaction is the key
modality for control of basic insect behaviour, such as ori
entation and movement toward, and interactions with, potential
mates, appro priate sites for oviposition, and sources of food. Not
surprisingly, therefore, much work on insect olfaction has been
motivated by long-term hopes of using knowledge of this pivotal
sensory system to design strategies for mon itoring and managing
harmful species and fostering the welfare of beneficial ones."
Intensive and extensive cultivation of grapes (Vitis vinifera L.)
leads to serious pest problem in vineyards in major grape growing
areas of the world. Climatic conditions in India are favorable for
high production of table and wine grapes, and thus also for
incidence of variety of pests. These include the sucking insect
pests namely thrips, hoppers, mealybugs etc., and beetle pests like
stem borer, stem girdler, flea beetles, chafer beetles, shot hole
borer and several lepidopteron, mites, nematodes and vertebrate
pests. Pests of grapes in other countries relevant to Indian
conditions are also dealt herewith since they may get introduced in
India in future. Up to date information on biology, damage,
seasonal development, management practices of the pests are covered
in this book. Some of the pest management practices followed in
other countries are also given, which will be useful to Indian
conditions. Pesticide residue is a serious problem both for export
and internal market in grapes. Guideline for pesticide residue
management in grapes is also given in this book. The authors have
tried to accommodate almost all the important information generated
on the grape pests up to 2012. A complete list of grape pests
(except disease) occurring in different grape growing regions of
the world is also covered in this book which will be ready reckoner
for the grape workers. The authors sincerely hope that this book
will provide useful information to many entomologists, students
working on grapes and the grape growers in the country. It is a
pleasure to thank all those people who gave help, suggestions and
encouragement in the preparation of our book "The Grape
Entomology".
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."
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.
