Agricultural Entomology is a vital branch of agricultural science that deals with the study of insects and other arthropods that affect agricultural crops either directly or indirectly. This includes not only harmful pests such as insect pests, nematodes, and mites, but also beneficial insects that contribute to pollination and biological control. The subject encompasses a comprehensive understanding of the morphology, taxonomy, physiology, and ecology of agriculturally important arthropods. This helps in accurate identification and classification of pests at various stages of their life cycles, which is crucial for planning effective control strategies.
Identification and Bionomics: Understanding the life cycle, habits, habitats, and behavior of insect pests that attack field crops, horticultural crops, and stored produce.
Nature of Damage and Symptoms: Studying the specific ways in which pests damage crops—such as boring, sap-sucking, defoliation, or root feeding—and recognizing the symptoms they cause, such as wilting, yellowing, stunted growth, or leaf spots.
Integrated Pest Management (IPM): Emphasis is placed on eco-friendly, cost-effective, and sustainable pest control through an integration of biological, cultural, mechanical, and chemical methods. IPM aims to minimize pesticide use, protect beneficial organisms, and reduce environmental hazards.
