Book Synopsis Life History and Notes on the Biology of Stelidota Octomaculata (Coleoptera by : Jimmy R. Galford
Download or read book Life History and Notes on the Biology of Stelidota Octomaculata (Coleoptera written by Jimmy R. Galford and published by . This book was released on 1991 with total page 12 pages. Available in PDF, EPUB and Kindle. Book excerpt: S2The life history of Stelidota octomaculata (Say) was studied in Ohio and Pennsylvania. This insect damages acorns and affects the establishment of oak seedlings. Acorns deployed in wire cages and pitfall traps plus a sampling of naturally occurring acorns were used to monitor insect activity. Adults overwinter in forest litter and begin feeding on undamaged germinating or damaged acorns in spring. Acorns damaged by the beetles may fail to produce seedlings. Beetle reproduction occurs in spring and early summer inside acorns both above and below ground. Reproduction ceases in late July to early August. Adult activity may continue until early December in some years. In the laboratory, a life cycle was completed in about 34 days at 220 to 26%. The maximum number of offspring from a female was 933 and the maximum lifespan at: room temperature was 238 days. Acorns of all oak species tested plus seeds of 28 other species were suitable for larval development. S3.

Download or read book The Nemonychidae, Anthribidae and Attelabidae (Coleoptera) of Northern Europe written by Hans G2nget and published by BRILL. This book was released on 2003-01-01 with total page 150 pages. Available in PDF, EPUB and Kindle. Book excerpt: This monograph deals with the species of the families Nemonychidae, Anthribidae and Attelabidae (Curculionoidea, Coleoptera) of Continental Europe north of 52 ° N and of the British Isles. 50 species are included. For each species a short diagnosis and detailed information on the taxonomy, nomenclature, geographic distribution, life habits, hosts and parasites is given.The book contains keys from family level to species and is finely illustrated with over 100 black and white drawings, almost all of which are originals drawn by the author and furthermore with four plates showing 35 representative species skilfully depicted in colour by Birgitte Rubæk.The introductory part provides general information on the taxonomic history, morphology of all life stages, life history and economic importance, comments on phylogeny and classification and some practical hints on how to collect, preserve and identify specimens. In addition lists of hosts and parasites, a catalogue of occurrence by province for the 33 species found in Fennoscandia and Denmark, an extensive list of literature and an index are given.The main objective of the book is to provide a comprehensive systematic treatment of the North European Nemonychidae, Anthribidae and Attelabidae based on richly illustrated identification keys and descriptions combined with up-to-date information on the distribution and biology of individual species. Volume 34 of this series treated the Brentidae. These volumes thus complete the treatment of the four orthocerous weevil families (weevils with straight antennae) within the superfamily Curculionoidea, and are indispensable for anyone - professional or amateur - working with or interested in weevils.
Book Synopsis The Origin and Evolution of Larval Forms by : Brian K. Hall
Download or read book The Origin and Evolution of Larval Forms written by Brian K. Hall and published by Gulf Professional Publishing. This book was released on 1999-01-12 with total page 466 pages. Available in PDF, EPUB and Kindle. Book excerpt: A classic problem in evolutionary biology is the origin of larvae - how and why did they occur? Indeed, it has often been suggested that many entirely unique body plans first originated as retained larvae of ancestral organisms. But what of the larvae themselves? What developmental and evolutionary forces shape and constrain them? These questions and others are dealt with by this international team of leading zoologists and developmental biologists. Intended to contribute to a continuing dialectic, this book presents diverse opinions as well as manifold conclusions. Certain to challenge and intrique, The Origin and Evolution of Larval Forms should be a part of the library of every evolutionary and developmental biologist interested in larvae and their significance.
Book Synopsis The Origins of Larvae by : Donald Williamson
Download or read book The Origins of Larvae written by Donald Williamson and published by Springer Science & Business Media. This book was released on 2003-12-31 with total page 284 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many biological facts are irreconcilable with the assumption that larvae and adults evolved from the same genetic stock. The author of this book draws attention to these, and presents his alternative hypothesis that larvae have been transferred from one taxon to another. In his previous book (Larvae and Evolution, 1992), the author used larval transfer to explain developmental anomalies in eight animal phyla. In the present book, he claims that the basic forms of all larvae and all embryos have been transferred from foreign taxa. This leads to a new, comprehensive theory on the origin of embryos and larvae, replacing the discredited 'recapitulation' theory of Haeckel (1866). Metamorphosis, previously unexplained, represents a change in taxon during development.

Download or read book Skeletal Musculature in Larval Phases of the Beetle Epicauta Segmenta (Coleoptera, Meloidae) written by A. Berrios-Ortiz and published by Springer. This book was released on 1979-07-31 with total page 122 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study, the first in an intended series of anatomical investigations of the blister beetles, was undertaken primarily for the purpose of determining the changes that occur in the skeletal musculature during postembryonic larval development. The species studied, Epicauta segmenta (Say), like others belong ing to the coleopterous family Meloidae, is characterized by hypermetamor phosis (SELANDER and WEDDLE, 1969). The egg develops into an active, well sclerotized larva that searches for grasshopper eggs, which, as in the case of all species of Epicauta, serve as the sole larval food. This triungulin phase of the larval stage, as it is called, is followed by the first grub phase (Fig. 1), during which the larva continues to feed and undergoes several molts. After feeding is completed the larva commonly enters a sessile, diapausing coarctate phase in which the integument is heavily sclerotized and the appendages, including the legs, are vestigial (Fig. 2). Following this the larva attains an active second grub phase (Fig. 3) closely resembling the first grub phase in external anatomy. Normally, the second grub phase leads directly to pupation and the formation of the adult. An alternate, abbreviated developmental pattern, involving pupation immediately after the first grub phase, is also recorded in this and many other species of Epicauta.

This book was released on 2018-09-08 with total page 164 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from The Argasidae of North America, Central America and Cuba The taxonomic study of the Argasidae has been beset with difficult problems, some of which are still unsolved. The principal difficulty has been and still is the lack of adequate generic characters. Some of the earlier species were described from very few specimens and frequently with very little knowl edge Oi their biologies. By 1908, Neumann and Nuttall had notably improved the situation by better generic definitions and the use of new specific characters. Both retained as genera only Argas and Ornithodoros. In 1912 Banks added the genus Otobius, and in 1942 Antricola was added by the authors. In 1908 only some twenty species were known. Now in North America alone there are at least twenty-five species and about thirty new species have been described from other countries. The characters exhibited by these new species have served to clarify certain of the taxonomic problems; they have made others more confusing. Some specific distinctions have found corrobora tive support in the biologies. With the increasing number of new species, it has become more and more difficult to separate Arga; and Ornithodoros and we have found it necessary to change the previous conceptions of these genera. However, no genera have been synonymized. It is probable that subsequent workers will find Others necessary but it is earnestly hoped that none will be erected until reliable generic criteria have been clearly established. The present names serve the purpose and should be changed only for permanent reasons. In a previous paper1 the senior author emphasized the importance of variation within species. This occurs principally in the ornamentation, and the morphology is reasonably constant. In the Argasidae it is perhaps too early to evaluate fully the variation within species, but at least it is evident that it is of little importance in the genus Ornithodoros. Ornamentation is absent in the known species of the Argasidae except in Ornithodoros coriaceus. Where confusion has arisen in specific identities, it has been due largely to overlooking characters in the mammillae and hypostome, some Of which are not very easily detected, and the very distinct ones found in the larval stage which heretofore has not been thoroughly studied.
