First edition of Darwin's primary work on plant fertilization. Detailing the relationship between the sexual structure of orchids and the insects that fertilize them, this was the first of three volumes that followed the publication of the Origin which contained supporting evidence for the author's theory of natural selection. Darwin concludes that plants are equal to animals in the marvels of their adaptation; for example, he observes that wind-pollinated flowers have no colours; it is only those insect-pollinated varieties that have bright coloured petals and sweet smelling nectars.

A quorum of scientists offer reviews and results to celebrate the 150th anniversary of 'On The Various Contrivances By Which British And Foreign Orchids Are Fertilised By Insects, And On The Good Effects Of Intercrossing' (1862). Authors of the first ten chapters follow research on the pollination and breeding systems of the same orchid lineages that interested Darwin, including temperate and tropical species. Authors on the last two chapters provide information on the floral attractants and flowering systems of orchids using protocols and technologies unavailable during Darwin's lifetime.

"Half of all insect species are dependent on living plant tissues, consuming about 10% of plant annual production in natural habitats and an even greater percentage in agricultural systems, despite sophisticated control measures. Plants are generally remarkably well-protected against insect attack, with the result that most insects are highly specialized feeders. The mechanisms underlying plant resistance to invading herbivores on the one side, and insect food specialization on the other, are the main subjects of this book. For insects these include food-plant selection and the complex sensory processes involved, with their implications for learning and nutritional physiology, as well as the endocrinological aspects of life cycle synchronization with host plant phenology. In the case of plants exposed to insect herbivores, they include the activation of defence systems in order to minimize damage, as well as the emission of chemical signals that may attract natural enemies of the invading herbivores and may be exploited by neighbouring plants that mount defences as well." "Insect-Plant Biology discusses the operation of these mechanisms at the molecular and organismal levels, in the context of both ecological interactions and evolutionary relationships. In doing so, it uncovers the highly intricate antagonistic and mutualistic interactions that have evolved between plants and insects. The book concludes with a chapter on the application of our knowledge of insect-plant interactions to agricultural production." "This multidisciplinary approach will appeal to students in agricultural entomology, plant sciences, ecology, and indeed anyone interested in the principles underlying the relationships between the two largest groups of organisms on earth: plants and insects."--BOOK JACKET.Title Summary field provided by Blackwell North America, Inc.

By now you've probably heard that bees are disappearing--but they aren't the only species at risk. Populations of fireflies, butterflies, and ladybugs have all been declining in recent years, too. This middle grade nonfiction explains the growth, spread, and recent declines of each of these four types of insects. Exploring human causes, like the Baltimore electric company that collected fireflies to attempt to harness their phosphorescent lighting source, to natural occurrences, like the mysterious colony collapse disorder that plagues bee populations, master nonfiction storyteller Mark Kurlansky shows just how much bugs matter to our world.
