Acquiring comprehensive knowledge of entomology is of paramount importance in implementing effective measures for controlling pests and in utilizing beneficial insects for the betterment of human society. This book focuses on the fundamental concepts of entomology, including the morphology, anatomy, adaptations, and classification of insects, particularly parasitic ones that cause harm to plants, livestock, and even humans. The economic role of insects is also discussed in detail, such as productive insects like honeybees, silkworms, and lac insects, as well as beneficial ones like parasitoids, predators, and pollinators.

The book covers pest management, which includes the usage of various plant protection chemicals, plant protection equipment, toxicology of pesticides, and compatibility of pesticides. Non-insect pests, such as nematodes and mites, are also discussed along with their economic role and control measures. The text is enhanced with numerous fine, hand-drawn figures and illustrations to aid in a better understanding of the subject matter.

This book is primarily intended for undergraduate students of agriculture, but will also be of use to postgraduate students of agriculture, officials working in the agriculture department, especially those involved in plant protection work, and the general public who have an interest in scientific agriculture.
