“Silkworm and Its Genetics: A Model for Lepidopteran Biology” explores the biology, genetics, and practical significance of the silkworm (Bombyx mori), one of the most studied insects in scientific research. The book highlights how silkworms serve as an ideal model for understanding Lepidopteran biology, including development, physiology, and genetic regulation. It connects fundamental science with applied aspects, making it valuable for students, researchers, and 
professionals in genetics, entomology, and sericulture. The book examines the silkworm's life cycle, anatomy, and physiology in detail, emphasizing traits that make it suitable for genetic studies. It discusses inheritance patterns, gene mapping, molecular genetics, and the use of silkworms in studying gene expression, mutation, and transgenesis. Additionally, the text highlights how silkworm genetics informs breeding programs, disease resistance, and silk production, bridging 
basic science with practical sericulture applications. This text is designed for students and researchers in genetics, entomology, biotechnology, and sericulture, as well as professionals in silk production. Through clear explanations, illustrative diagrams, and real-world examples, it provides readers with a deep understanding of silkworm biology and genetics.
