Hardcover. Zustand: New. Contents: I. Insects. II. Morphology of insects. III. Anatomy of insects. IV. Classification. Insects are ubiquitous and are found all over the world, in the Lithosphere, Hydrosphere and Biosphere. According to evidences insects appeared on this planet Earth some 440 million years ago, long before the appearance of man in this world. Because of their dynamic adaptational traits insects have escaped extinction all these years. Insects have the innate ability to adapt themselves to any kind of adverse environmental conditions. The morphology and anatomy of insects, as well as their mode of life are quite important factors that help in the development of traits for adaptation. In this book the authors have given a detailed account of the general aspects of insects, as well as morphology and anatomy of insects. Studies on such aspects about insects are ultimately aimed at devising and adopting physical, mechanical, chemical or biological control measures to combat the insects, which have turned into pests and pose a serious problem to mankind. The text is substantiated with many fine, hand-drawn figures that will help better understanding of the book and make the reading more interesting.

Hardcover. Zustand: New. Contents: 1. Introduction. 2. Diseases of spice crops. 3. General characters of pathogens affecting spice crops.

Hardcover. Zustand: New. This book provides a comprehensive introduction to the history, development, and application of pest control methods, with a particular focus on chemical pesticides and plant protection technologies. Designed primarily for undergraduate students of agriculture, it also serves as a valuable resource for postgraduate students of entomology, professionals in plant protection, and enthusiasts in the field. The text traces the evolution of pest management, from the early use of natural and inorganic compounds to the advent of synthetic pesticides like DDT and the development of modern formulations with reduced mammalian toxicity and quick knockdown effects. It also covers advancements in plant protection appliances, from hand-operated sprayers to aerial spraying techniques for large-scale pest control. Enriched with hand-drawn illustrations and insights from both Indian and international sources, the book combines scientific rigor with practical relevance. The authors extend their gratitude to colleagues and publishers for their support in bringing this resource to fruition.
