Download or read book Insect Mouthparts written by Harald W. Krenn and published by Springer Nature. This book was released on 2019-12-09 with total page 688 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the first comprehensive book focusing on the form and function of insect mouthparts. Written by leading experts, it reviews the current knowledge on feeding types and the evolution of mouthparts and presents new research approaches. The richly illustrated articles cover topics ranging from functional morphology, biomechanics of biting and chewing, and the biophysics of fluid-feeding to the morphogenesis and genetics of mouthpart development, ecomorphology in flower-visiting insects as well as the evolution of mouthparts, including fossil records. Intended for entomologists and scientists interested in interdisciplinary approaches, the book provides a solid basis for future scientific work.

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.

Available in PDF, EPUB and Kindle. Book excerpt: Insects are the most diverse group of organisms in the 3 billion-year history of life on Earth, and the most ecologically dominant animals on land. This book chronicles for the first time the complete evolutionary history of insects: their living diversity, relationships and 400 million years of fossils. Whereas other volumes have focused on either living species or fossils, this is the first comprehensive synthesis of all aspects of insect evolution. The book is illustrated with 955 photo- and electronmicrographs, drawings, diagrams, and field photos, many in full colour and virtually all of them original. The book will appeal to anyone engaged with insect diversity: professional entomologists and students, insect and fossil collectors, and naturalists.
