LONDON AND TONBRIDGE PREFACE DURING recent years the study of insect pests has received an increasing degree of attention, an attention which is in every way justified when the effects produced by this type of nuisance is taken into consideration. Now, with the onset of hostilities and the altered, indeed revolutionized conditions associated therewith, the problem has assumed even greater magnitude. What was formerly and far too often considered little more lian a nuisance, has now been finally recognized as a definite menace. The evacuation problem, the herding together of Military, Naval and Air Force personnel in emergency quarters, the mobilization of Civil Defence Units, even the necessary alterations in the sanitary staffs of local authorities all these factors have played and are still playing an important part in bringing the insect pest into the foreground of our national conscience. For this reason the authors hope that the present volume will prove of some definite and practical use to those authorities and individuals who have the responsi bility of insect pest control placed in their charge. An attempt has been made to cover the necessarily extensive field as adequately as possible, but in a volume such as this it will be evident that some aspects of the problem have had to receive less extensive treatmentthan others which appeared to possess more urgent and important claims. In a practical handbook such as this, summarised treatment is probably an advantage, VI PREFACE and it will also be appreciated that in no other way could the material at the authors disposal have been compressed into adequate space. The authors trust that the essentials have been given requisite attention, and that no fundamental aspect of the problem has been omitted. The authors wish to tender their most grateful thanks to L. Peverett, Esq., and his associates for numerous courtesies and expert assistance at various stages in the preparation of this volume and to Dr. Fenton, Royal Borough of Kensington, and Dr. Dart, of the Metropoli tan Borough of Hackney, for permission to reproduce various forms and office records. They are also indebted to Dr. Vynne Barland, Metropolitan Borough of Bethnal Green, for permission to reproduce propaganda leaflets. Acknowledgment is also made to H. M. Stationery Office for permission to include extracts from certain Acts of Parliament, Statutory Rules and Orders. They are prevented, through circumstances over which they have no control, from acknowledging their indebtedness to an eminent authority on insect pests, but they would never theless like it to be known that their gratitude is none the less sincere.
