For several years Mr. William Opp hinted broadly to me that a book on standard methods for mosquito control should be written, a sort of manual for mosquito-control workers. I think he intended something like an engineering manual, with a series of formulas and descriptions of techniques. Gradually the hints turned into a more-direct request, amply decorated with assurances of the need for such a book, until my resistance broke down, and I accepted the challenge with a great deal of reservations. I am not certain that the results of my labors turned out to be quite what was expected, but I hope they will be of some use, anyway. According to Webster's Dictionary, a manual is a handy book for use as a guide. As long as we are dealing with exact sciences such as chemistry, physics and mathematics, it is possible to make such a guide of standard methods. A manual for mosquito control deals only in part with exact sciences when it gives standard methods, e.g. pesticide mixes, calibration of equipment and application rates. But the most important ingredient of efficient mosquito control is knowledge of the biology of mosquitoes, and there are very few universal laws that cover biology. The behavior of a mosquito species may change from one end of its distribution to the other. Although no absolute standards can be given for biology, it is essential for a manual on mosquito control to mention various biological traits of the mosquitoes, but it must be kept in mind that we are dealing with living animals who will adapt to different localities. Each control district has its own set of mosquito problems, and each district is dealing with them in a different way. This manual is meant as a general guide, but each district must adapt it to the individual circumstances. For many, this book will contain nothing new, but it is hoped that the manual may at least help those training to conduct some phase of mosquito control.
