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 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 ...
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.
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...
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 ...
These compounds are synthesized in arthropods from dietary cholesterol upon metabolism by the Halloween family of cytochrome P450s. [ 6 ] Compounds with ecdysteroid activity in arthopods are not only produced by these animals ( zooecdysteroids ).
Whether snipping, ripping or gripping, mandibles help arthropods get the job done, and mandibulates diversified so successfully that today they make up more than half of all animal species ...
