A devastating examination of how collapsing insect populations worldwide threaten everything from wild birds to the food on our plate. From ants scurrying under leaf litter to bees able to fly higher than Mount Kilimanjaro, insects are everywhere. Three out of every four of our planet’s known animal species are insects. In The Insect Crisis, acclaimed journalist Oliver Milman dives into the torrent of recent evidence that suggests this kaleidoscopic group of creatures is suffering the greatest existential crisis in its remarkable 400-million-year history. What is causing the collapse of the insect world? Why does this alarming decline pose such a threat to us? And what can be done to stem the loss of the miniature empires that hold aloft life as we know it? With urgency and great clarity, Milman explores this hidden emergency, arguing that its consequences could even rival climate change. He joins the scientists tracking the decline of insect populations across the globe, including the soaring mountains of Mexico that host an epic, yet dwindling, migration of monarch butterflies; the verdant countryside of England that has been emptied of insect life; the gargantuan fields of U.S. agriculture that have proved a killing ground for bees; and an offbeat experiment in Denmark that shows there aren’t that many bugs splattering into your car windshield these days. These losses not only further tear at the tapestry of life on our degraded planet; they imperil everything we hold dear, from the food on our supermarket shelves to the medicines in our cabinets to the riot of nature that thrills and enlivens us. Even insects we may dread, including the hated cockroach, or the stinging wasp, play crucial ecological roles, and their decline would profoundly shape our own story. By connecting butterfly and bee, moth and beetle from across the globe, the full scope of loss renders a portrait of a crisis that threatens to upend the workings of our collective history. Part warning, part celebration of the incredible variety of insects, The Insect Crisis is a wake-up call for us all.

Leading experts in the field bring together diverse aspects of insect timing mechanisms. This work combines three topics that are central to the understanding of biological timing in insects: circadian rhythms, photoperiodism, and diapause. The common theme underlining each of the contributions to this book is an understanding of the timing of events in the insect life cycle. Most daily activities (emergence, feeding, mating, egg laying, etc.) undertaken by insects occur at precise times each day. Likewise, seasonal events such as the entry into or termination from an overwintering dormancy (diapause) occur at distinct times of the year. This book documents such events and provides an up-to-date interpretation of the molecular and physiological events undergirding these activities. The study of circadian rhythms has undergone a flowering in recent years with the molecular dissection of the components of the circadian clock. Now that many of the clock genes have been identified it is possible to track daily patterns of clock-related mRNAs and proteins to link the entraining light cycles with molecular oscillations within the cell. Insect experiments have led the way in demonstrating that the concept of a "master clock" can no longer be used to explain the temporal organization within an animal. Insects have a multitude of cellular clocks that can function independently and retain their function under organ culture conditions, and they thus offer a premier system for studying how the hierarchical organization of clocks results in the overall temporal organization of the animal. Photoperiodism, and its most obvious manifestation, diapause, does not yet have the molecular underpinning that has been established for circadian rhythms, but recent studies are beginning to identify genes that appear to be involved in the regulation of diapause. Overall, the book presents the rich diversity of challenges and opportunities provided by insects for the study of timing mechanisms.

Chances are that just under a nearby rock, you'll spot a roly-poly pill bug. Encourage a child to take a close look, and introduce a fascinating creature. Gently pick it up and watch as it rolls into a ball and unrolls to take a walk. This cousin to lobsters and crabs sheds its crusty skin and will tickle your hand with its 14 (count 'em ) wiggly legs. Awaken a sense of wonder in a child with the Next Time You See series from NSTA Kids. The books will inspire elementary-age children to experience the enchantment of everyday phenomena, such as pill bugs, fireflies, seashells, and sunsets. Free supplementary activities are available on the NSTA website. Especially designed to be experienced with an adult--be it a parent, teacher, or friend--Next Time You See books serve as a reminder that you don't have to look far to find something remarkable in nature.

For decades fruit growers have sprayed their trees with toxic chemicals in an attempt to control a range of insect and fungal pests. Yet it is possible to grow apples responsibly, by applying the intuitive knowledge of our great-grandparents with the fruits of modern scientific research and innovation. Since The Apple Grower first appeared in 1998, orchardist Michael Phillips has continued his research with apples, which have been called "organic's final frontier." In this new edition of his widely acclaimed work, Phillips delves even deeper into the mysteries of growing good fruit with minimal inputs. Some of the cuttingedge topics he explores include: The use of kaolin clay as an effective strategy against curculio and borers, as well as its limitations Creating a diverse, healthy orchard ecosystem through understory management of plants, nutrients, and beneficial microorganisms How to make a small apple business viable by focusing on heritage and regional varieties, value-added products, and the "community orchard" model The author's personal voice and clear-eyed advice have already made The Apple Grower a classic among small-scale growers and home orchardists. In fact, anyone serious about succeeding with apples needs to have this updated edition on their bookshelf.

In this landmark volume, an international group of scientists has synthesized their collective expertise and insight into a newly unified vision of insect societies and what they can reveal about how sociality has arisen as an evolutionary strategy. Jürgen Gadau and Jennifer Fewell have assembled leading researchers from the fields of molecular biology, evolutionary genetics, neurophysiology, behavioral ecology, and evolutionary theory to reexamine the question of sociality in insects. Recent advances in social complexity theory and the sequencing of the honeybee genome ensure that this book will be valued by anyone working on sociality in insects. At the same time, the theoretical ideas presented will be of broad-ranging significance to those interested in social evolution and complex systems.
