Preface Immunity in insects is different from immunity in vertebrates. Insects lack immunoglobulins even though they are capable of reacting against foreign components with effective defense mechanism. There has been a marked advancement in most of the fields of science in the past two decades. Insect immunity is also one of them. It is a developing subject which is now established as a new branch in insect study. This treatise is an attempt to compile meaningful articles of leading workers in this field, nevertheless we do not claim that leadership in insect immunity is by any means restricted to them. The idea is to provide a vibrant description of various aspects of "Insect Immunity". With the rapid development of the subject, it is difficult for any one author to discuss all the aspects of an area in a limited number of pages, even then they have done their utmost to include the entire development of the subject in their articles. The treatise deals with insect haemocytes, their population, isolation and role in defense mechanism, humoral encapsulation, inducible humoral antibacterial immunity, cellular immune reactions, role of endocrines, role of prophenol oxidase system in cellular communication, haemagglutinins and impact of parasite on insect immune system. Some topics could not be covered because experts in those area though willing could not complete their commitment within time limits. Variation in approach, style and form is bound to be there in different chapters as no restriction was placed on the authors to organise their views in the manner they liked best. Author was also free to use the terminology, definitions and concepts which he regarded the best. We have no hesitation in admitting that readers may find a different opinions regarding a few topics in the existing literature as I, as the editor, have not interfered with the opinions and expression of the authors. My gratitude to the authors for their kind cooperation and immense patience. I am grateful to Dr. A.B. Saxena, Professor, School of studies in Zoology, Vikram University, Ujjain and to my colleagues and students whose advice and suggestions were gratefully received.
