FOREWORD

Mosquitoes have generally been credited as the worst pests of man and animals, but ticks, in spite of their lack of wings, could truly be considered to run them a close second both as pests and as vectors of an even wider variety of diseases of man and animals. Because of the varied habits of different species of ticks, of first importance to an understanding of the problems they create is an accurate knowledge of their taxonomy and biology.

Among the continents, Africa in particular is burdened with more than its share of species. This first in a series of volumes, with emphasis on the Sudanese tick fauna, will provide the basic systematic and biological information that can safely be said to bear in a major way on the entire continent. Many of these species occur far beyond the region under discussion.

It will be evident to the specialized reader that the author not only has a scholarly command of the pertinent literature based on exhaustive library work and liaison with competent authorities, but an unusual field experience of personal collecting in Africa and elsewhere in the world. More than this, he has been able to straighten out a number of knotty problems, particularly in the genera Argas, Ornithodoros, Haemaphysalis, and Hyaloma, which contain important disease carrying species, through study of his own and of various museums' extensive collections. This expansion of our knowledge of African ticks will be a major contribution, and provide authoritative reference work for years to come. For example, here for the first time is brought together the extensive literature on Ornithodoros moubata, the relapsing fever tick, notorious since Livingstone's vividly described, evil encounters with it in the Congo.

Most of the important species of African ticks are found in the Sudan. The few that are not, plus such aspects as relationships to disease, will be treated in companion volumes to follow so that the future student of any phase of the entire continental tick fauna will undubitably resort to these elegant contributions as his major reference.

The United States Navy is to be congratulated for its foresightness in supporting this timely and continuing work through its Naval Medical Research Unit Number Three in Cairo, Egypt.
