This work takes a fresh, modern approach to investigate and explain the predator and prey relationships of insects and spiders, the major terrestrial fauna on earth. Devoted to broad and in-depth analysis of arthropod defenses against predators, the book's approach is both experimentally and theoretically based with major emphasis on evolution, predator strategies and tactics, and prey defensive adaptations and behaviors. The authors explain such topics as cryptic and aposematic coloration, the conflict between sexual and survival needs, web spider prey choice and evolution of prey counter defenses, predator-prey interactions and the origins of intelligence, bird predatory tactics, and caterpillar defense strategies. Also examined is the use of timing for fitness and survival, evolutionary gamesmanship in the predatory bat-moth relationship, colony defense by aper wasps, startle as a defense by moths, aggregation as a defense, chemicals as defenses, plant chemicals as defenses, and venoms as defenses. The authors illustrate each topic with numerous specific well-documented examples presented in a clear, readable style.
Insects live all over the world and are food for many animals, including other insects! Children will be fascinated to learn about the many ways these tiny creatures defend themselves against predators. Well-written text, full-color photographs, and clearly labeled illustrations help children discover - The senses insects use to avoid predators - How insects bite and sting to defend themselves - How insects blend in with their surroundings in order to remain unnoticed - How the brightly colored bodies of some insects warn predators to stay away Teacher's guide available.
Mostly tiny, infinitely delicate, and short-lived, insects and their relatives—arthropods—nonetheless outnumber all their fellow creatures on earth. How lowly arthropods achieved this unlikely preeminence is a story deftly and colorfully told in this follow-up to the award-winning For Love of Insects. Part handbook, part field guide, part photo album, Secret Weapons chronicles the diverse and often astonishing defensive strategies that have allowed insects, spiders, scorpions, and other many-legged creatures not just to survive, but to thrive. In 69 chapters, each brilliantly illustrated with photographs culled from Thomas Eisner’s legendary collection, we meet a largely North American cast of arthropods—as well as a few of their kin from Australia, Europe, and Asia—and observe at firsthand the nature and extent of the defenses that lie at the root of their evolutionary success. Here are the cockroaches and termites, the carpenter ants and honeybees, and all the miniature creatures in between, deploying their sprays and venom, froth and feces, camouflage and sticky coatings. And along with a marvelous bug’s-eye view of how these secret weapons actually work, here is a close-up look at the science behind them, from taxonomy to chemical formulas, as well as an appendix with instructions for studying chemical defenses at home. Whether dipped into here and there or read cover-to-cover, Secret Weapons will prove invaluable to hands-on researchers and amateur naturalists alike, and will captivate any reader for whom nature is a source of wonder.
Insect-Plant Interactions and Induced Plant Defence Chair: John A. Pickett, 1999 This book examines the sophisticated mechanisms that plants use to defend themselves against attack by insects and pathogens, focusing on the networks of plant signalling pathways that underlie these defences. In response to herbivory, plants release a complex blend of as many as 100 volatile chemicals, known as semiochemicals ('sign chemicals'). These act as an airborne SOS signal, revealing the presence of the herbivore to the predators and parasitoids that are its natural enemies. Plants also have endogenous defence mechanisms that can be induced in response to pathogens, and separate chapters deal with systemic acquired resistance, phytoalexins, and the interacting pathways in pathogen and pest resistance. The book discusses underlying biochemical mechanisms by which plant stress leads to the biosynthesis of chemical signals from pools of secondary metabolite precursors, or even from the primary metabolism source. Finally, consideration is given to the possibilities for exploiting these signalling pathways by plant molecular genetics. The use of plant signals and their analogues to switch on defence pathways in crop plants is covered in depth. Bringing together contributions from entomologists, chemical ecologists, molecular biologists and plant physiologists this book is truly interdisciplinary, and will be essential reading for anyone with an interest in agricultural pest control.
This series presents critical reviews of the present position and future trends in modern chemical research.
Examines how insects have been used as weapons in wartime conflicts throughout history, presenting as examples how scorpions were used in Roman times and hornets nests were used during the MIddle Ages in siege warfare and how insects have been used in Vietnam, China, and Korea.
Watch out for these masters of defense—stick insects! Their secret weapon is being able to hide in plain sight. To protect themselves from predators, they have developed long, narrow bodies. They blend right in to the branches they live on. Some stick insects even have extra growths that look like leaves for more camouflage. Stick insects also protect themselves by being most active at night when it is even harder to see them. They escape from predators by dropping to the forest floor, where they look like fallen sticks and leaves. In this exciting book, you can learn what makes stick insects similar to and different from other insects. Close-up photographs and diagrams reveal extraordinary details about stick insects' bodies, both inside and out. And you can perform activities that help you observe how stick insects live and how they hide by keeping still. Learn more about this exciting member of nature's fascinating Insect World!
Chemical Defenses of Arthropods charts the significant progress in the study of chemical defenses in arthropods, a rapidly expanding area of chemical ecology. The book groups the defensive compounds secreted by arthropods based on their main functionalities and sequentially lists them according to their carbon numbers. Organized into 19 chapters, this volume begins with an overview of the defensive exudates of arthropods and how arthropods have exploited these compounds to deter the ubiquitous and omnipresent predators around them. The next chapters introduce the reader to the defensive compounds produced in the exocrine glands of arthropods, ranging from alcohols and ketones to hydrocarbons, carboxylic acids, esters, 1,4-quinones and hydroquinones, lactones, phenols, steroids, and proteinaceous venoms. The book also discusses the taxonomic value of arthropod defensive compounds, with emphasis on factors affecting the composition of defensive secretions and taxonomic correlations that utilize them. Later chapters focus on arthropod biosynthesis of exocrine compounds, how insects tolerate the presence of plant toxins in their diets, and identified defensive compounds in arthropods. The book concludes with an analysis of the properties and characteristic distributions of arthropod natural products, along with their adaptiveness as defensive agents. This book is a valuable resource for biologists and chemists.
An examination of the characteristics, habitat and behavior of insects, including comprehensive picture keys for insect identification.
Never leave a bug behind -- Collect all the Battle Bugs books! Max Darwin is called back to Bug Island urgently. Lizards have been spotted making landfall on the banks of the Roaring Rapids river. Max soon realizes that the lizards are just a small nuisance compared to the giant that's been ferrying them across from Reptile Island. Admiral Longtooth, a huge saltwater crocodile, is determined to show the bugs that the battle may be over, but they'll never win the war.
