Excerpt from Recent Advances in Entomology IN preparing a second edition of this book two reasons have led to the decision to confine its scope within the original limits. Firstly, in any attempt to discuss recent advances in entomology, at all exhaustively, several volumes, each the size of the present one, would be needed. Even to include adequate extra chapters the size of the book would need to be increased a good deal beyond its prescribed limits. Secondly, those other aspects of entomology that commend themselves for inclusion are, to a large extent, provided for elsewhere. In this connection, insect physiology, insects and climate, general morphology, insects and plant viruses, for example, have already formed the subjects of recent books or monographs. The writers of these several books have discussed such subjects far more adequately than could be expressed within the limits of single chapters. Certain aspects of entomology, naturally, have required more revision than others. Under morphology, while current Views on Wing Venation have undergone but little change, Head Segmentation and the Genitalia have needed considerable revision. Also, recent studies of the musculature have led to revision of views respecting the homologies of certain of the appendages and their parts. As regards Metamorphosis, discoveries in regard to the presence of hormones are discussed. Palaeontology has developed so rapidly as to require very full revision of the original chapter: several new illustrations, taken from recent papers by Dr. F. M. Carpenter, have been included in this chapter with the author's permission. In dealing with the Sense Organs the subject of response to visual stimuli has been extended so as to include the results of a good deal of recent investigation. In this connection valuable help has been given by Dr. M. Hertz, which is here gratefully acknowledged. The subject of Stimulatory Organs has also been included. With regard to Biological Races.

In recent years the field of entomology, due in part to the penetration of other disciplines, has made rapid progress. “Recent Advances in Entomological Research: From Molecular Biology to Pest Management” includes 25 chapters contributed by more than 40 distinguished entomologists and introduces the latest progress in entomology, from molecular biology, insect-plant interactions and insecticide toxicology, to emerging technologies in pest management. Not only is the book interesting and informative, but it provides useful, innovative research advances and will serve as a valuable resource for entomologists, zoologists, botanists and other researchers in the field of plant protection.
