This book conveys a wealth of information on pesticide chemistry, biochemical modes of action, biological activity, and theory of pesticide application for management programs. Emphasis is placed on novel biological insecticides which block certain stages in the development of pest insects. Special attention is given to insecticides with selective properties. Their role in integrated pest management programs and in insecticide resistance management strategies is discussed. The data and concepts presented are essential in establishing new technologies and developing novel groups of compounds which will determine our future agricultural practices. Everybody involved in crop protection and developing new insecticide chemistry from universities to chemical industries will benefit from this volume.

Professor Albert S. Perry passed away suddenly on February 18, 1992, leaving behind his grieving family, friends and colleagues. It was his aspiration to produce a comprehensive work on insecticides to summarize his lifelong dedication to the field of entomology and public health. On the day before his operation, he expressed his desire with the following words: . "1 am coming out of this surgery and will recuperate from it as soon as possible for the sake of my boy (then aged three) and the book". He also told me that he would like to add a chapter on IPM (Integrated Pest Management) and suggested that we write it together. The sad reality is that none of this took place the way he had planned and these became his last words. On my own, I found it difficult to proceed with the writing of the IPM chapter, since several chapters are required to cover· this subject and, in fact, several books. are already devoted to IPM. There was even an IPM article written in a journal (Awake 1983) for a general audience to which he commented that he would like to use it someday because it was well written for laymen, thus providing the readers a wide selection of journals and books to choose from.

The aim of this book is quite ambitious: here, we attempt to bridge the gap between soH physicists, agronomists, horticulturists, hydraulic engineers, de signers, manufacturers and users of drip irrigation systems. We believe that progress in drip irrigation hinges on the contributions of professionals made in all related disciplines and their cooperation. The last decade has seen great development in the field of drip irrigation, al though the drip-irrigated area has not increased at the same rate as in the pre vious decade. However, our understanding of the processes involved in water and solute distribution and in plant response has increased vastly. The tools for op timal design of drip systems have improved tremendously. The main progress has been in the development and in the manufacture of sophisticated equipment; not only improved types of emitters and laterals, but also auxiliary equipment such as new filtration systems, controllers and sensors. In this book we highlight the need to maintain a proper balance between the hydraulic design of drip systems and aspects of their management and maintenance. Drip irrigation has a potential for high water use efficiency, but many well-designed systems suffer from bad management. We are indebted to the late Eshel Bresler for his contribution to our under standing of water and solute movement under drip irrigation and its appli cation to system design.
