This book essentially covers all aspects of study of insects covering aspects of morphology, physiology, ethology, ecology, taxonomy with emphasis on bioecology and management of insects of economic importance in the fields of agriculture, horticulture, medicine and veterinary. About this edition With the factors controlling gene expression being better understood, interest in crop transformations resulting from transgenic is on the rise. The book emphasizes the increased involvement of interdisciplinary trends, the diversity of approaches as well as developments that make insect science truly integrated. • IPM or integrated Pest Management, a concept involving the optimum combination of control methods to reduce pest population to below a threshold level. Such an approach, which calls for an integration of crop production, combination of agronomic, genetic, chemical and biological methods in the crop production system has been outlined in the book. • The increased relevance of biopesticides involving plant-derived products, new molecules, which have replaced earlier insecticides, fungicides and herbicides, the increasing role of biological control as of host plant resistance have been emphasized. • The role of biodiversity in the effective functioning of ecosystems has been detailed. • The role of insect taxonomy, wherein while retaining the importance of insects of pestological value, has also let to the revision of existing terminologies of species, besides adding several new taxa. • Every aspect of insect science including industrial entomology.
