Insect Metamorphosis


Book Description

Insect Metamorphosis: From Natural History to Regulation of Development and Evolution explores the origin of metamorphosis, how it evolved, and how it is it regulated. The book discusses insect metamorphosis as a key innovation in insect evolution. With most of the present biodiversity on Earth composed of metamorphosing insects—approximately 1 million species currently described, with another 10-30 million still waiting to be discovered, the book delves into misconceptions and past treatments. In addition, the topic of integrating insect metamorphosis into the theory of evolution by natural selection as noted by Darwin in his On the Origin of Species is also discussed. Users will find this to be a comprehensive and updated review on insect metamorphosis, covering biological, physiological and molecular facets, with an emphasis on evolutionary aspects. - Features updated knowledge from the past decade on the mechanisms of action of juvenile hormone, the main doorkeeper of insect metamorphosis - Aids researchers in entomology or developmental biology dealing with specialized aspects of metamorphosis - Provides applied entomologists with recently updated data, especially on regulation, to better face the problems of pest control and management - Gives general evolutionary biologists context on the process of metamorphosis in its larger scope

The Transformations (or Metamorphoses) Of Insects, (Insecta, Myriapoda, Arachnida, and Crustacea)


Book Description

Excerpt from The Transformations (or Metamorphoses) Of Insects, (Insecta, Myriapoda, Arachnida, and Crustacea): Being an Adaptation, for English Readers, of M. Emile Blanchard's "Metamorphoses, Moeurs Et Instincts Des Insects"; And a Compilation From the Works of Newport, Charles Darwin, and Others The articulate animals comprise those which the great Linnaeus called insects -that is to say, the true insects, the hundred-legs, the spiders, and the crabs. Insects existed in very remote geological ages, and their wings have been found beautifully preserved in the remains of those old forests and swamps which have been formed into coal. Thus early in the world's history the beetle droned at eventide, and the merry chirp of the grasshopper was added to the song of Nature. Moreover, the hundred-legs of the period enjoyed the quietude of the great tree stems, and many a spider spread its web on the ferns and the close underwood. Coal is dug up from depths of hundreds of fathoms, and is covered by sediments which are the remains of old continents, and sea bottoms, the thickness of which is a measure of the time they took to form; yet so far back in the annals of Nature the tiny insects came from the egg, lived as gormandising grubs, changed into sleepy pupae, and burst forth into lively winged creatures. Ever since, and during all the successive changes of the world's surface, insect life has manifested itself, and now articulate animals are found everywhere.

Metamorphoses


Book Description

The discussions about the ethical, political and human implications of the postmodernist condition have been raging for longer than most of us care to remember. They have been especially fierce within feminism. After a brief flirtation with postmodern thinking in the 1980s, mainstream feminist circles seem to have turned their back on the staple notions of poststructuralist philosophy. Metamorphoses takes stock of the situation and attempts to reset priorities within the poststructuralist feminist agenda. Cross-referring in a creative way to Deleuze's and Irigaray's respective philosophies of difference, the book addresses key notions such as embodiment, immanence, sexual difference, nomadism and the materiality of the subject. Metamorphoses also focuses on the implications of these theories for cultural criticism and a redefinition of politics. It provides a vivid overview of contemporary culture, with special emphasis on technology, the monstrous imaginary and the recurrent obsession with 'the flesh' in the age of techno-bodies. This highly original contribution to current debates is written for those who find changes and transformations challenging and necessary. It will be of great interest to students and scholars of philosophy, feminist theory, gender studies, sociology, social theory and cultural studies.
