Acquiring knowledge about different aspects of entomology is of vital importance in adopting appropriate measures for the control of pests and also for utilizing the beneficial insects for the benefits of man. This book deals with the basic concepts of entomology, which include: - Morphology, anatomy, adaptation and classification of insects, especially the parasitic ones, which do harm to plants, livestock and even to man. Economic role of insects with special reference to productive ones such as, honeybee, silk worm and lac insect as well as beneficial ones such as, parasitoids, predators pollinators etc. Pest management that covers usage of various plant protection chemicals, plant protection equipments, toxicology of pesticides, compatibility of pesticides etc. Non-insect pests viz., nematodes and mites, their economic role and control measures. The text is substantiated with many fine, hand-drawn figures and illustrations that will help better understanding of the text. The book, which is primarily intended for the undergraduate students of agriculture, will be of use to the postgraduate students of agriculture, to the officials working in the department of agriculture, especially those involved in plant protection work and also to the elite public who are interested in scientific agriculture.

Larry Pedigo and Marlin Rice have produced the top pest management textbook on the market for decades. New co-author Rayda Krell has helped bring the book into the twenty-first century. The successful core concepts of the book—understanding pests in their environment and using an ecological approach to combat them—remain as robust as ever. Features that instructors have come to rely on have been retained, including insect diagnostic boxes with detailed information on important species and species groups and an appendix with keys to major insect orders. New material on genetically modified plant species and regional pest technologies complement concepts in basic and applied entomology. Taxonomies and systematics of insects have been updated throughout the book.

Excerpt from Elements of Entomology: An Outline of the Natural History and Classification of British Insects Amongst the numerous works published on Entomology, it appeared to the author that there was none which gave, in a popular and readable form, an outline of the principal groups into which Insects are usually divided. It was with the object of filling up this gap in our Entomological literature that the present little book was written. The plan which the author laid down for himself at starting, and to which he has endeavoured to adhere closely throughout, consisted in passing lightly over the surface of the subject, avoiding details as much as was consistent with giving a true picture of the principal phænomena of Insect life; and with the view of bringing the subject home to his readers as closely as possible, he has always endeavoured to select, as examples of each group, those common insects which occur almost everywhere.
