Excerpt from Life Histories of Indian Insects, Vol. 5: Lepidoptera (Butterflies) The insects, the life-histories of which are described in this volume, are representatives of the principal families of that interesting group of insects, the Butterflies. With the exception of one (delias) the others are pests of more or less economic import ance, occurring on trees and plants either cultivated or grown for the garden. All are of interest and importance in that they are probably the first to attract the attention of the beginner in Ento mology, especially Economic Entomology. Also they occur so constantly and are so common that in all their stages, they ftc quently come under the notice of even the common people, but for want of a proper knowledge and observation ordinary people fail to see the connection between the caterpillar which eats the leaves, the dormant pupa and the butterfly which incessantly flies about under trees, over bushes and plants and not infrequently in houses or even over one's head. The hanging Nymphalid, Papilionid and Pierid pupae are frequently mistaken for fruits by many. For the progress of Economic Entomology in India it is essential that the people should become familiar with the insects and especially with their life-history. The greatest bar to progress in checking injurious insects here is the fact that a mysterious origin is usually assigned to them, simply because the elementary and essential facts of insect transformations are not known to those who suffer from the depre.

This is the first book devoted to the interest taken by amateur British collectors in Indian insects between 1750 and 1947, many employed as soldiers and medics by the East India Company. Initially confined to the building up of personal collections (many of which would later form the foundation of the London Natural History Museum’s collection), the early entomologists also donated specimens to the Asiatic Society of Bengal, the Bombay Natural History Society and local museums. Some published their findings in the journals of these institutions. Towards the end of the nineteenth century, interest in entomology shifted to focus on insect pests and their economic impact on forestry and horticulture. The result was the founding of the Institutes of Forestry and Horticulture at Dehra Dun and Pusa, where Indian scientists continue to conduct entomological research today. The present work elucidates this previously under-researched aspect of British insect history, documenting the people, places, publications and institutions associated with the exploration of the rich entomological fauna of the Indian subcontinent.

Pests cause damage to the economic value of crops and stored products, while vectors are responsible for the transmission of disease-causing agents in human beings and livestock. Although application of synthetic pesticides in agriculture gives immediate relief, it also causes well-known side effects, leading to a consensus among entomologists and agriculturists to shift towards other ecofriendly pest management methods. Natural enemies of insects including their 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 successful group of natural enemies. Highly specialized/generalized in their prey choice, active stages of predators search for a suitable prey, attack or kill the prey and consume prey within a short handling time. Predatory ability is known to increase with increase in prey density. A single predator may devour several prey individuals. Exploiting this potency of parasitoids may yield successful results in controlling notorious pests in an ecofriendly way. This book provides information on the important biocontrol agents that are effective in pest suppression. It starts with insect parasitic groups followed by specific group of parasitoids. It is hoped that the book presents a comprehensive account of beneficial parasitoids and will be useful to undergraduate and postgraduate students of Entomology, Biological Control, Plant Protection, Agricultural Zoology and Zoology, besides those involved in competitive examinations and policy planning. Features Each chapter has been authored by specialized senior professionals Every chapter contains Learning Objectives and Points to Remember This book offers comprehensive knowledge of parasitoids and their application in pest management in a lucid way
