E-book Collecting and Preserving Insects and Mites : Techniques and Tools
The Class Arthropoda, which includes insects, spiders, mites, and their relatives, is without question the most successful group of organisms on the planet. Insects alone account for nearly 55% of all species known to science (Barrowclough 1992). Spiders, mites and insects inhabit every terrestrial habitat on the planet and play a major role in the evolution and maintenance of biotic communities. They are the primary pollinators of flowering plants; they are important consumers and recyclers of decaying organic matter; and they are integral components in the foodwebs of vertebrates and other invertebrates. For these reasons, and many others, the study of insects and their relatives is of increasing importance as society faces increased challenges to preserve and enhance environmental quality, reduce pesticide usage, increase crop productivity, control food costs, and increase trade in the global community. Pest species are responsible for enormous economic losses annually, attacking crops and ornamental plants, causing damage to our food and clothing, and vectoring diseases that effect cultivated plants, our pets and livestock, and ourselves. The damage cause by pests species is far outweighed by the positive effects of beneficial species. Pollinators ensure the production of fruit, parasitoids and predators help control pest species, some species contain chemicals of pharmaceutical value, and a large number of species contribute to the decomposition and recycling of dead and decaying matter.
