Book Description
Insects are the most numerous class of animals or earth, both in terms of their number and their variety. There are 800,000 recognized species, with between 1 and 10 million estimated species yet to be classified. This book will discuss, mechanics of flight, Wing structure, Hovering flight, flight in smaller and larger insects and wing polars.

Book Description
From the rain forests of Borneo to the tenements of Manhattan, winged insects are a conspicuous and abundant feature of life on earth. Here, Robert Dudley presents the first comprehensive explanation of how insects fly. The author relates the biomechanics of flight to insect ecology and evolution in a major new work of synthesis. The book begins with an overview of insect flight biomechanics. Dudley explains insect morphology, wing motions, aerodynamics, flight energetics, and flight metabolism within a modern phylogenetic setting. Drawing on biomechanical principles, he describes and evaluates flight behavior and the limits to flight performance. The author then takes the next step by developing evolutionary explanations of insect flight. He analyzes the origins of flight in insects, the roles of natural and sexual selection in determining how insects fly, and the relationship between flight and insect size, pollination, predation, dispersal, and migration. Dudley ranges widely--from basic aerodynamics to muscle physiology and swarming behavior--but his focus is the explanation of functional design from evolutionary and ecological perspectives. The importance of flight in the lives of insects has long been recognized but never systematically evaluated. This book addresses that shortcoming. Robert Dudley provides an introduction to insect flight that will be welcomed by students and researchers in biomechanics, entomology, evolution, ecology, and behavior.

Book Description
The flight muscles of gian water bugs provide the best material for a study of the peculiar properties of insect fibrillar muscle. Although little was previously known about the biology of these insect, three species, Lethocerus maximus, L. annulipes and B. Malkini have now been extensively studied in the field in Trinidad and the techniques for breeding L. maximus and B. malkini worked out. Against the background of studies carried out in Oxford in the last four years (Pringle, 1967) special attention was given to the biochemistry of the ATPase activity of actomyosin and myofibrils prepared from fibrillar flight muscles (Maruyama and Allen, 1967; Maruyama, Pringle and Tregear, in press). This enzyme is similar to that from vertebrate muscle in its sensitivity to ionic strength and its requirements for MgATP as substrate but its dependence on the concentration of Ca(2+) is different and this is related to the stretch activation shown by intact glycerinated muscle preparations (Ruegg and Tregear, 1966). Previous studies (Chaplain, 1966) suggested an important role for ADP in the control of ATPase activity of insect actomyosin. Further studies show that the ionic strength of the medium has an important effect on the inhibition or activation produced by ADP (Maruyama and Pringle, 1967). (Author).
