Cultural entomology

Human interactions with insects include both a wide variety of uses, whether practical such as for food, textiles, and dyestuffs, or symbolic, as in art, music, and literature, and negative interactions including serious damage to crops and extensive efforts to eliminate insect pests. Academically, the interaction of insects and society has been treated in part as cultural entomology, dealing mostly with 'advanced' societies, and in part as ethnoentomology, dealing mostly with 'primitive' societies, though the distinction is weak and not based on theory. Both academic disciplines explore the parallels, connections and influence of insects on human populations, and vice versa. They are rooted in anthropology and natural history, as well as entomology, the study of insects. Other cultural uses of insects, such as biomimicry, do not necessarily lie within these academic disciplines. More generally, people make a wide range of uses of insects, both practical and symbolic. On the other hand, attitudes to insects are often negative, and extensive efforts are made to kill them. The widespread use of insecticides has failed to exterminate any insect pest, but has caused resistance to commonly-used chemicals in a thousand insect species. Practical uses include as food, in medicine, for the valuable textile silk, for dyestuffs such as carmine, in science, where the fruit fly is an important model organism in genetics, and in warfare, where insects were successfully used in the Second World War to spread disease in enemy populations. One insect, the honey bee, provides honey, pollen, royal jelly, propolis and an anti-inflammatory peptide, melittin; its larvae too are eaten in some societies. Medical uses of insects include maggot therapy for wound debridement. Over a thousand protein families have been identified in the saliva of blood-feeding insects; these may provide useful drugs such as anticoagulants, vasodilators, antihistamines and anaesthetics. Symbolic uses include roles in art, in music (with many songs featuring insects), in film, in literature, in religion, and in mythology. Insect costumes are used in theatrical productions and worn for parties and carnivals. Culture consists of the social behaviour and norms found in human societies and transmitted through social learning. Cultural universals in all human societies include expressive forms like art, music, dance, ritual, religion, and technologies like tool usage, cooking, shelter, and clothing. The concept of material culture covers physical expressions such as technology, architecture and art, whereas immaterial culture includes principles of social organization, mythology, philosophy, literature, and science. This article describes the roles played by insects in human culture so defined. Ethnoentomology developed from the 19th century with early works by authors such as Alfred Russel Wallace (1852) and Henry Walter Bates (1862). Hans Zinsser's classic Rats, Lice and History (1935) showed that insects were an important force in human history. Writers like William Morton Wheeler, Maurice Maeterlinck, and Jean Henri Fabre described insect life and communicated their meaning to people 'with imagination and brilliance'. Frederick Simon Bodenheimer's Insects as Human Food (1951) drew attention to the scope and potential of entomophagy, and showed a positive aspect of insects. Food is the most studied topic in ethnoentomology, followed by medicine and beekeeping. In 1968, Erwin Schimitschek  claimed cultural entomology as a branch of insect studies, in a review of the roles insects played in folklore and culture including religion, food, medicine and the arts. In 1984, Charles Hogue covered the field in English and from 1994 to 1997, Hogue's The Cultural Entomology Digest served as a forum on the field. Hogue argued that 'Humans spend their intellectual energies in three basic areas of activity: surviving, using practical learning (the application of technology); seeking pure knowledge through inductive mental processes (science); and pursuing enlightenment to taste a pleasure by aesthetic exercises that may be referred to as the 'humanities.' Entomology has long been concerned with survival (economic entomology) and scientific study (academic entomology), but the branch of investigation that addresses the influence of insects (and other terrestrial Arthropoda, including arachnids and myriapods) in literature, language, music, the arts, interpretive history, religion, and recreation has only become recognized as a distinct field through Schimitschek's work.Hogue set out the boundaries of the field by saying: 'The narrative history of the science of entomology is not part of cultural entomology, while the influence of insects on general history would be considered cultural entomology.' He added: 'Because the term 'cultural' is narrowly defined, some aspects normally included in studies of human societies are excluded.'
