The arthropods are a phylum of animals with jointed legs; they include the insects, arachnids such as spiders, myriapods, and crustaceans. [1] Insects play many roles in culture including their direct use as food, [2] in medicine, [3] for dyestuffs, [4] and in science, where the common fruit fly Drosophila melanogaster serves as a model organism for work in genetics and developmental biology.
The intentional cultivation of insects and edible arthropods for human food is now emerging in animal husbandry as an ecologically sound concept. Several analyses have found insect farming to be a more environmentally friendly alternative to traditional animal livestocking.
The eggs, larvae, pupae, and adults of certain insects have been eaten by humans from prehistoric times to the present day. [8] Around 3,000 ethnic groups practice entomophagy. [9] Human insect-eating (anthropo-entomophagy) is common to cultures in most parts of the world, including Central and South America, Africa, Asia, Australia, and New ...
Extant marine arthropods range in size from the microscopic crustacean Stygotantulus to the Japanese spider crab. Arthropods' primary internal cavity is a hemocoel, which accommodates their internal organs, and through which their haemolymph - analogue of blood - circulates; they have open circulatory systems. Like their exteriors, the internal ...
Likewise, the relationships between various arthropod groups are still actively debated. Today, arthropods contribute to the human food supply both directly as food, and more importantly, indirectly as pollinators of crops. Some species are known to spread severe disease to humans, livestock, and crops. (Full article...
The "Spanish fly", Lytta vesicatoria, has been considered to have medicinal, aphrodisiac, and other properties. 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 damage to crops and extensive efforts to control insect pests.
Scientists have solved a long-standing mystery about how the extinct arthropod Odaraia alata snipped, gripped and ripped its way to ancient survival. Ancient swimming ‘taco’ had ‘bug jaws ...
Humans also unintentionally eat arthropods in other foods, [148] and food safety regulations lay down acceptable contamination levels for different kinds of food material. [ Note 4 ] [ Note 5 ] The intentional cultivation of arthropods and other small animals for human food, referred to as minilivestock , is now emerging in animal husbandry as ...
