Résumé :

Insect Sampling in Forest Ecosystems highlights the problems faced by entomologists working in forest ecosystems. It suggests ways in which their methodology can be modified so as to be understood by ecologists and become accepted within the general fields of ecology and entomology.Insect sampling, although firmly based on standard ecological census techniques, presents special problems that are not faced by other ecologists. With the small size, varied life cycles, rapid rates of increase, and ingenious adaptations to habitats of insects, ecological entomologists face problems that are somewhat different to those faced by vertebrate or plant ecologists. Furthermore, forest ecosystems, whether natural or manmade, present special problems to the ecologists working beneath their canopies.This book will be essential reading for advanced students and researchers as well as teachers across the whole spectrum of education. Insects play a major part in all aspects of ecology. It brings together the methodology needed to investigate insects through the various strata of the forest canopy. It covers techniques associated with various specialised groups of forest insects. Each chapter is backed up by a sound approach to experimental design and data analysis. It presents the following chapters : 1- Sampling theory and practice 2- Sampling insects from roots: 3- Pitfall trapping in ecological studies 4- Sampling methods for forest understorey vegetation 5- Sampling insects from trees: shoots, stems, and trunks 6- Insects in flight 7- Techniques and methods for sampling canopy insects 8- Sampling methods for water-filled tree holes and their artificial analogues 9- Sampling devices and sampling design for aquatic insects 10- Methods for sampling termites 11- Parasitoids and predators
