Insects as a group occupy a middle ground in the biosphere between bacteria and viruses at one extreme, amphibians and mammals at the other. The size and general nature of insects present special problems to the study of entomology. For example, many commercially available instruments are geared to measure in grams, while the forces commonly encountered in studying insects are in the milligram range. Therefore, techniques developed in the study of insects or in those fields concerned with the control of insect pests are often unique. Methods for measuring things are common to all sciences. Advances sometimes depend more on how something was done than on what was measured; indeed a given field often progresses from one technique to another as new methods are discovered, developed, and modified. Just as often, some of these techniques find their way into the classroom when the problems involved have been sufficiently ironed out to permit students to master the manipulations in a few laboratory periods. Many specialized techniques are confined to one specific research laboratory. Although methods may be considered commonplace where they are used, in another context even the simplest procedures may save considerable time. It is the purpose of this series (1) to report new developments in methodology, (2) to reveal sources of groups who have dealt with and solved particular entomological problems, and (3) to describe experiments which may be applicable for use in biology laboratory courses.

This text book aims at to provide an up to date, general and applied account of Entomology which is written in a simple and lucid language keeping in view the syllabi of Entomology in M.Sc. Zoology & M.Sc. (Ag.) of various Indian Universities. The book will also be useful to those who are preparing for competitive examinations conducted by various central & state Government agencies for recruitment. The book is equally useful to those dealing with pests and pest control. It is hoped the book will be useful not only to students but also to agriculturist, horticulturist, foresters, veterinary and clinical doctors and laymen dealing with pest control.

Keeping the requirements of teachers and researchers in mind, this encyclopedic dictionary presents the terminology in entomology and pest management in the most authentic and comprehensive way. It also includes terms related to the close relatives of insects, such as mites and ticks and some other organisms which are pests of crops.

Insects, when studied from the ecological perspective, provide a great opportunity for scientific studies emphasizing population theory. The simple fact of being successful organisms for their ability to colonize different habitats or even for their high reproductive potential, increases the interest of ecologists in conducting studies focused on population and community level. Mathematical models are powerful tools that can capture the essence of many biological systems and investigate ecological patterns associated to ecological stability dependent on endogenous and exogenous factors. This proposal comes from the idea of adding experiences of researchers interested in working at the interface between mathematical and computation theory and problems centered on entomology, showing how mathematical modelling can be an important tool for understanding population dynamics, behavior, pest management, spatial structure and conservation.

Excerpt from Applied Entomology: An Introductory Text-Book of Insects in Their Relations to Man If one can judge from the answers to about fifty letters of inquiry sent to teachers of Entomology in colleges in the United States, the teaching of Entomology in this country at the present time is in a rather chaotic condition. Very few of the answers received show much in harmony in subject matter, methods of presentation, or even the line of training the students should receive by a course in the subject. The author believes that in agricultural colleges at least, two distinct groups of students need a knowledge in Entomology, and rather early in their course. One of these groups is composed of students who will never specialize in the subject but need it as part of an agricultural education, and particularly as a tool which they can use wherever insects are related to their special lines of work. They are not particularly interested in such details as the number of antennal segments in insects, the number of branches of the radial vein, or how important a pest on pigweed the insect is: they do not expect to identify insects beyond the order or family at most, relying on specialists available at the State Experiment Stations for such information. But they do desire a general knowledge of the broad outlines of the subject, and a rather complete knowledge of, and if possible, the ability to recognize particularly import ant insect pests they are liable to meet in the course of their work. The other group consists of those who expect to specialize in the subject, becoming professional entomologists. Their needs will, of course, be different from those of the other group, but an introductory survey such as will meet the requirements of the rest will give the members of this group an excellent foundation for further and more detailed work. The present book is therefore Offered as a classroom text for an introductory course in the subject, which shall give a general idea of insects, their structure, life histories, and habits, with methods for the control of insect pests in general, followed by a more thorough study of the more important ones found in this country. For use, the writer believes that in few places will all of the text be assigned. Instead, the pests of the country as a whole (treated in large type) and those of the particular region concerned (selected from among those printed in smaller type) would naturally be the parts used in any one place, though the book as a whole should be fairly well applicable to all sections of the country.
