Parasitoids in Pest Management
Pests cause economic damage to crops and stored products, while vectors are responsible for the transmission of disease-causing agents in human beings and livestock. Although the application of synthetic pesticides in agriculture has given immediate relief, it has also caused well-known side effects, leading to a general consensus among entomologists and agriculturists to shift towards other ecofriendly pest management. Insect natural enemies consisting of predators, parasitoids, and pathogens have attracted the attention of scientists across the globe. These natural enemies exist in agroecosystems and suppress the populations of pests. Parasitoids are farmers’ friends and the most success...
Insect Predators in Pest Management

Industrial Entomology
This book is a compilation of writings focused on conventional and unconventional insect products.

Commercial Insects
Despite being the biggest group of organisms inhabiting Earth in both diversity and sheer numbers, insects are barely commercialized. Most of the standard textbooks of applied entomology talk about insect pest management, and when it comes to commercial aspects of insects, only apiculture, sericulture, and lac culture are talked about. This book will help bring other commercial uses of insects and their economic potential to the fore. This will generate interest in further research on the commercial potential of insects, thereby harnessing a much-found resource. The book has the following salient features: 1. Encompasses all major aspects of beneficial and commercial insects. 2. Deals with edible insects and mass culture of natural enemies and beneficial insects. 3. Emphasis on the mass cultivation of beneficial insects for obtaining yields. 4. Discusses stingless bees and their products. 5. Helps to solve the problem of food scarcity and improve food security.
The Indo-Aryan Languages
The Indo-Aryan languages are spoken by at least 700 million people throughout India, Pakistan, Bangladesh, Nepal, Sri Lanka and the Maldive Islands. They have a claim to great antiquity, with the earliest Vedic Sanskrit texts dating to the end of the second millennium B.C. With texts in Old Indo-Aryan, Middle Indo-Aryan and Modern Indo-Aryan, this language family supplies a historical documentation of language change over a longer period than any other subgroup of Indo-European. This volume is divided into two main sections dealing with general matters and individual languages. Each chapter on the individual language covers the phonology and grammar (morphology and syntax) of the language and its writing system, and gives the historical background and information concerning the geography of the language and the number of its speakers.

Learning Abroad
Commonwealth scholarships began in 1959. They have since moved over 30,000 people across borders, launching them into influence as politicians, poets, painters, professors – and the rest. Their stories illuminate the sociology and politics of higher education, of the Commonwealth, and of its member countries: they include the last scholar before apartheid took South Africa out of the Commonwealth, who became a high court judge, and the first after it came back, now a vice-chancellor. The second edition of this book, revised and updated since it was first published to mark the scholarships’ jubilee, sets out the narrative of the scholarship plan from its unlikely conception in a Commonwea...
