Book Description
Readers enter the intriguing world of invasive insect species with this text, a fun yet informative look at the insects whose goal is not just to survive, but to dominate new territories. Readers will be amazed at how the tiniest creatures can take down entire trees, fields of fauna, and even other insects by simply upsetting the delicate balance of the ecosystems they invade. Readers are encouraged to think critically about the relationships between living things. Colorful photographs accompany the age-appropriate text, and informative fact boxes offer even more fascinating information.

Book Description
Biological control of insect pests, plant pathogens, and weeds is the only major alternative to the use of chemical pesticides in agriculture and forestry. This book is the first comprehensive attempt at a balanced benefit/risk assessment of biological control. It covers classical biological control of pests and weeds, augmentation of natural enemies, and the use of biopesticides. Unique sections deal with genetic engineering of biocontrol agents and crop plants, economic analysis of biocontrol, and the ecological consequences of the introduction of organisms. The book will be of interest to researchers and postgraduate students in biotechnology, agriculture, forestry, and environmental sciences.

Book Description
This overview of the roles of alien species in insect conservation brings together information, evidence and examples from many parts of the world to illustrate their impacts (often severe, but in many cases poorly understood and unpredictable) as one of the primary drivers of species declines, ecological changes and biotic homogenisation. Both accidental and deliberate movements of species are involved, with alien invasive plants and insects the major groups of concern for their influences on native insects and their environments. Risk assessments, stimulated largely through fears of non-target impacts of classical biological control agents introduced for pest management, have provided valuable lessons for wider conservation biology. They emphasise the needs for effective biosecurity, risk avoidance and minimisation, and evaluation and management of alien invasive species as both major components of many insect species conservation programmes and harbingers of change in invaded communities. The spread of highly adaptable ecological generalist invasive species, which are commonly difficult to detect or monitor, can be linked to declines and losses of numerous localised ecologically specialised insects and disruptions to intricate ecological interactions and functions, and create novel interactions with far-reaching consequences for the receiving environments. Understanding invasion processes and predicting impacts of alien species on susceptible native insects is an important theme in practical insect conservation.

Book Description
The 11th International Symposium on Insect-Plant Relationships (SIP11), held on August 4-10, 2001, in Helsingør, Denmark, followed the tradition of previous SIP meetings and covered topics of different levels from chemistry, physiology, and ethology to ecology, genetics, and evolution of insect-plant relationships. The present volume includes a representative selection of fully refereed papers as well as a complete list of all the contributions which were presented at the meeting. Reviews of selected topics as well as original experimental data are included. The book provides valuable information for students and research workers interested in chemical and biological aspects of interactions between individuals and populations of different organisms.

Book Description
Nonindigenous plants and plant pests that find their way to the United States and become invasive can often cause problems. They cost more than $100 billion per year in crop and timber losses plus the expense of herbicides and pesticides. And this figure does not include the costs of invasions in less intensively managed ecosystems such as wetlands. Nonindigenous Plants and Plant Pests examines this growing problem and offers recommendations for enhancing the science base in this field, improving our detection of potential invaders, and refining our ability to predict their impact. The book analyzes the factors that shape an invader's progress through four stages: arriving through one of many possible ports of entry, reaching a threshold of survival, thriving through proliferation and geographic spread, and ultimate impact on the organism's new environment. The book also reviews approaches to predicting whether a species will become an invader as well as the more complex challenge of predicting and measuring its impact on the environment, a process involving value judgments and risk assessment. This detailed analysis will be of interest to policymakers, plant scientists, agricultural producers, environmentalists, and public agencies concerned with invasive plant and plant pest species.

Book Description
One of the world's most insightful writers on the subject brings together an array of important and readable information on the ways in which insects and plants coexist in nature. Interrelationship Between Insects and Plants is a rare and expansive look at the intertwining of these two vastly different species. Its aim is to summarize in a simple and understandable way the basis of food selection among insects, and to review the various sides of their relationships with plants.

Book Description
Insects are a group of abundant and diverse organisms that have successfully adapted to the most challenging conditions on earth. The success of insects in adverse environments indicates the advanced defense mechanisms employed by these organisms, but they are often targeted by specialized microorganisms (viruses, bacteria, nematodes, & fungi) and parasitoids. Insects exhibit both humoral and cellular immune responses against pathogens. The lack of an adaptive immune system has compelled insects to choose immediate non-specific but sophisticated responses that include the production of antimicrobial peptides, phenoloxidase, apoptosis, phagocytosis, encapsulation, and nodulation. In recent decades, technological advances have been made in decrypting the molecular and mechanistic basis of insect immunity. However, there is a need to understand the insect immune responses to single or mixed encounters. Future challenges include a better understanding of functional cooperation of various endosymbiotic microbes and their role in insect defenses. Post-transcriptional modulation of immune responses regulated by non-coding RNAs (microRNA & long non-coding RNAs) has become critically important to study by using modern bioinformatics and experimental tools. Therefore, investigating the dynamics of insect immune responses will substantially increase the capacity for confronting harmful agricultural and medical pests. Furthermore, most insect cellular immune activities have been conducted in a laboratory setting, therefore confirming the existing knowledge in a natural environment would provide crucial information.

Book Description
Reflects on insect pests' evolution by evaluating existing theories, documenting case studies of diverse pest species and presenting new concepts regarding the problem of variation and implications for pest management strategies. Leading experts offer contributions which deal with variations in genetic markers and ecologically meaningful traits as well as future perspectives in entomology and biosystematics.
