Available in PDF, EPUB and Kindle. Book excerpt: Homologies of the parts of the maxilla and the labium of mosquito larvae were studied. The name cardobasistipes is proposed for the triangular sclerite lateroposterior of the maxilla, previously known as the cardo or the palpifer. The numbers of serrations on the prementum and submentum were found to be of taxonomic value. The sequence of mouthpart movements of filter feeding and browsing species, and the progress of food particles from the feeding current into the mouth were observed. Differences in stiffness were found among the setae in different positions on the mouthparts. These differences were confirmed by staining the cuticle with Mallory's triple stain and are correlated with the functions of the setae during feeding. Flexible serrations at the tips of the labral brush hairs are used for raking food particles in most of the browsing species of Aedes and Culiseta studied. When in pond water neither the browsing nor the filter feeding larvae select the type of food they ingest. Feeding behavior of the predatory larvae of Chaoborus americanus (Johannsen) and Mochlonyx velutinus (Ruthe) was observed. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: The, structure and function of the mouthparts of mosquito larvae were studied. Emphasis was placed on the study of the controversial homologies of parts of the maxilla and the labium. The name cardobasistipes is proposed for the triangular sclerite posterior to the base of the maxilla, previously known as the cardo or the palpifer. The numbers of serrations on the plates of the prementum and the submentum were found to be of taxonomic value. The mechanism of movement of the hairs of the labral brushes was elucidated, central movement is musculated, lateral return is by elasticity. Various degrees of flexibility of the cuticle of the mouthparts were found by staining with Mallory's triple stain. This variation was confirmed by observing the mouthparts of several species in action. The serrated tips of the labral brush hairs, present in most of the browsing species of Aedes and Culiseta that were studied, are flexible in spite of their function which is raking of food particles from surfaces. Other larvae, Culex territans, Culiseta morsitans, whose labral brushes consist of long, simple hairs, do not browse, but filter out food from the water which is brought to the mouth by the labral brush current. Since the size range of food particles found in the guts of these larvae was similar to the size range of the spaces between the labral brush hairs, it is correct to refer to these larvae as filter feeders. After browsing larvae were kept in a suspension of charcoal in water, the particles from their guts were measured and were compared with the dimensions of the natural food particles. The particles of charcoal were smaller than those of the natural food in larvae of the same species. The filter feeding mechanism was employed by the browsers in the suspension of charcoal in water. No selection in the type of natural food ingested was found among the browsing and filter feeding larvae. The morphology of the mouthparts of the larvae of Aedes canadensis and A. cinereus was found to be intermediate between those of the typical filter feeding and typical browsing species. Both filter feeding and browsing were observed in each species. The feeding behavior of the predatory larvae of Chaoborus and Mochlonyx was observed. Cannibalism was observed among the larvae of M. velutinus.

Download or read book Manual of Techniques in Insect Pathology written by Lawrence A. Lacey and published by Academic Press. This book was released on 1997-02-27 with total page 441 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biological Techniques is a series of volumes aimed at introducing to a wide audience the latest advances in methodology. The pitfalls and problems of new techniques are given due consideration, as are those small but vital details not always explicit in the methods sections of journal papers. In recent years, most biological laboratories have been invaded by computers and a wealth of new DNA technology and this will be reflected in many of the titles appearing in the series. The books will be of value to advances researches and graduate students seeking to learn and apply new techniques, and will be useful to teachers of advanced undergraduate courses involving practical or project work. This manual describes the broad array of techniques that are used in insect pathology. It will provide biologists, insect pathologists, entomologists, and those interested in biological control, with the necessary information to work on a variety of pathogen groups. This book will be an essential laboratory reference for insect pathologists. Features include: * Step by-step instructions on how to isolate, identify, culture, bioassay and store the major groups of entomopathogens * Details of the practical knowledge needed by beginners to apply the techniques * Chapters written by an international group of experts * Discussion of safety testing of entomopathogens in mammals and also broader methods such as microscopy and molecular techniques * Provides extensive supplemental literature and recipes for media, fixatives and stains

Download or read book Biology of Blood Sucking Insects written by Mike Lehane and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 301 pages. Available in PDF, EPUB and Kindle. Book excerpt: Blood-sucking insects are the vectors of many of the most debilitating parasites of man and his domesticated animals. In addition they are of considerable direct cost to the agricultural industry through losses in milk and meat yields, and through damage to hides and wool, etc. So, not surprisingly, many books of medical and veterinary entomology have been written. Most of these texts are organized taxonomically giving the details of the life-cycles, bionomics, relationship to disease and economic importance of each of the insect groups in turn. I have taken a different approach. This book is topic led and aims to discuss the biological themes which are common in the lives of blood-sucking insects. To do this I have concentrated on those aspects of the biology of these fascinating insects which have been clearly modified in some way to suit the blood-sucking habit. For example, I have discussed feeding and digestion in some detail because feeding on blood presents insects with special problems, but I have not discussed respiration because it is not affected in any particular way by haematophagy. Naturally there is a subjective element in the choice of topics for discussion and the weight given to each. I hope that I have not let my enthusiasm for particular subjects get the better of me on too many occasions and that the subject material achieves an overall balance.
Download or read book Regulation Digestion Nutrition Excretion written by G. A. Kerkut and published by Elsevier. This book was released on 2013-10-22 with total page 656 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this volume, seven of the chapters deal with feeding and diet, which is reasonable since insects consume an estimated l5-20% of all the world's planted crops. Many insects even have a specialized larval feeding stage that usually occupies a different ecological niche to the adult and so does not compete for the adult's food stock. Other chapters describe the means by which insects maintain their water balance, nitrogen balance and temperature balance under a range of conditions. These involve regulation by hormonal and behavioural systems that are also described here. The l4 chapters are all extensively illustrated and referenced and therefore provide excellent summaries of current knowledge. They will be of great value to entomologists, zoologists and biologists in general.

Download or read book Principles of Insect Morphology written by R. E. Snodgrass and published by Cornell University Press. This book was released on 2018-05-31 with total page 684 pages. Available in PDF, EPUB and Kindle. Book excerpt: This classic text, first published in 1935, is once again available. Still the standard reference in the English language, Principles of Insect Morphology is considered the author's masterpiece. A talented artist as well as one of the leading entomologists of his day, Robert E. Snodgrass produced a wealth of publications that display an accuracy and precision still unsurpassed. The 19 chapters in this volume cover each group of insect organs and their associated structures, at the same time providing a coherent morphological view of their fundamental nature and apparent evolution. To accomplish this aim, Snodgrass compares insect organs with those of other arthropods. Each chapter concludes with a glossary of terms. The 319 multipart illustrations are an invaluable source of information and have never been duplicated. This edition includes a new foreword by George Eickwort, Professor of Entomology at Cornell University, which relates the book to today's courses in insect morphology. Republication of this textbook will provide another generation of students with an essential foundation for their studies in entomology.
