Captures the full scope of the literature, integrating ecological and molecular mechanisms that enable insects to enter a dormant state.
Our highly seasonal world restricts insect activity to brief portions of the year. This feature necessitates a sophisticated interpretation of seasonal changes and enactment of mechanisms for bringing development to a halt and then reinitiating it when the inimical season is past. The dormant state of diapause serves to bridge the unfavourable seasons, and its timing provides a powerful mechanism for synchronizing insect development. This book explores how seasonal signals are monitored and used by insects to enact specific molecular pathways that generate the diapause phenotype. The broad perspective offered here scales from the ecological to the molecular and thus provides a comprehensive view of this exciting and vibrant research field, offering insights on topics ranging from pest management, evolution, speciation, climate change and disease transmission, to human health, as well as analogies with other forms of invertebrate dormancy and mammalian hibernation.
Many authors of this new book were participants at the workshop on diapause in aquatic invertebrates (Pallanza, Italy 2003). This book consists of two major parts: phenomenology of diapause and significance of this adaptation in scientific and practical uses. It combines the theoretical part with the application of knowledge on diapause in the wide spectrum of scientific and applied fields.
This volume is an outgrowth of a Symposium entitled "Evolution of Escape in Space and Time" held at the XV International Congress of Entomology in Washington, D. C., USA in August, 1976. The choice of topic was prompted by recent advances in evolutionary ecology and the apparent suitability of insect migration and dia pause as appropriate material for evolutionary studies. In the event, that choice seems amply justified as I hope a perusal of these papers will show. These Sympos ium papers hardly cover the topic of the evolution of escape mechanisms exhaustively, and I am sure everyone will have his favorite lacuna. Some of the more obvious ones are indicated by Professor Southwood in his Co...

They Dine in Darkness by Arthur Leo Zagat is a spellbinding tale of suspense and supernatural dread that will keep you on the edge of your seat. When a series of gruesome disappearances plague a quiet town, the locals whisper about a hidden society that meets under the cover of darkness. As an intrepid reporter delves deeper into the mystery, he uncovers a chilling truth about the sinister rituals that occur each night. With danger lurking at every corner and time running out, can he expose the malevolent forces before they claim their next victim? Enter the world where shadows conceal unspeakable horrors and uncover the truth behind the chilling dinners held in darkness.
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.
This balanced comprehensive account traces the alterations in body form undergone by insects as they adapt to seasonal change, exploring both theoretical aspects and practical issues. Topics explored include natural history, genetics, evolution, and management of insect adaptations.
