736 and, consequently, make them valuable in teaching and research. Even at the pre-college level, these attributes, plus their remarkable diversity of form and habits, make insects an important resource both in and outside the classroom (Matthews et al., 1997). The fruit fly, Drosophila melonagaster with its array of mutants, is familiar to all who take an elementary college genetics class, though it must also be appreciated that the insect continues to have an important role in advanced genetic research. Studies on other insects have provided us with much of our basic knowledge of animal and cell physiology, particularly in the areas of nutrition, metabolism, endocrinology, and neuromuscular physiology. Investigations into the population dynamics of some pest insects, especially forest species, led to the formulation of some important concepts in population ecology (Gillott, 1985).

With the development of microbial resistance to many antibiotics, there has been a revival in the use of maggot therapy, the use of fly larvae to clean wounds and promote healing (Sherman et al., 2000). Maggot therapy has been used for centuries in some societies and probably developed as a result of casual observations that the larvae of some myiasis-causing flies had beneficial effects on infected wounds. Myiasis, the infestation of animal tissues (living or dead) by maggots, appears to have evolved in some Dipteran families that were originally saprophagous, that is, bred in carrion. Currently, it is mostly seen in three families: Oestridae (all 150 species), Sarcophagidae, and Calliphoridae (about 80 species in total) (Chapter 9, Section 3). However, most of these species are unsuitable for use in maggot therapy because they feed on healthy tissue, are highly host-specific, and have other disadvantages. Of the 10 or so species of "medicinal maggots," the most common are larvae of the greenbottle fly, Lucilia sericata. Curiously, in the United Kingdom, continental Europe, and New Zealand, this fly is a major sheep pest, causing "strike," which may be fatal in heavy infestations (Sherman et al., 2000).

Many insects give us pleasure through their aesthetic value. Because of their beauty, certain groups, especially butterflies, moths, and beetles, are sometimes collected as ahobby. Some are embedded in clear materials from which jewelry, paperweights, bookends, place mats, etc., are made. Others are simply used as models on which paintings and jewelry are based.
