Chemical signals among organisms form "a vast communicative interplay, fundamental to the fabric of life," in the words of one expert. Chemical ecology is the the discipline that seeks to understand these interactions-to use biology in the search for new substances of potential benefit to humankind. This book highlights selected research areas of medicinal and agricultural importance. Leading experts review the chemistry of * Insect defense and its applications to pest control. * Phyletic dominance--the survival success of insects. * Social regulation, with ant societies as a model of multicomponent signaling systems. * Eavesdropping, alarm, and deceit--the array of strategies used by insects to find and lure prey. * Reproduction--from the gamete attraction to courtship nd sexual selection. * The chemistry of intracellular immunosuppression. Topics also include the appropriation of dietary factors for defense and communication; the use of chemical signals in the marine environment; the role of the olfactory system in chemical analysis; and the interaction of polydnaviruses, endoparasites, and the immune system of the host.

Imagine beetles ejecting defensive sprays as hot as boiling water; female moths holding their mates for ransom; caterpillars disguising themselves as flowers by fastening petals to their bodies; termites emitting a viscous glue to rally fellow soldiers--and you will have entered an insect world once beyond imagining, a world observed and described down to its tiniest astonishing detail by Thomas Eisner. The story of a lifetime of such minute explorations, For Love of Insects celebrates the small creatures that have emerged triumphant on the planet, the beneficiaries of extraordinary evolutionary inventiveness and unparalleled reproductive capacity.To understand the success of insects is to appreciate our own shortcomings, Eisner tells us, but never has a reckoning been such a pleasure. Recounting exploits and discoveries in his lab at Cornell and in the field in Uruguay, Australia, Panama, Europe, and North America, Eisner time and again demonstrates how inquiry into the survival strategies of an insect leads to clarifications beyond the expected; insects are revealed as masters of achievement, forms of life worthy of study and respect from even the most recalcitrant entomophobe. Filled with descriptions of his ingenious experiments and illustrated with photographs unmatched for their combination of scientific content and delicate beauty, Eisner's book makes readers participants in the grand adventure of discovery on a scale infinitesimally small, and infinitely surprising.

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 sixty-nine 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.
