An insect uses its digestive system to extract nutrients and other substances from the food it consumes. [3]Most of this food is ingested in the form of macromolecules and other complex substances (such as proteins, polysaccharides, fats, and nucleic acids) which must be broken down by catabolic reactions into smaller molecules (i.e. amino acids, simple sugars, etc.) before being used by cells ...
icipe's commercial insect-technology packages are designed to assist communities in East Africa to improve their livelihoods through income-generating activities like silk and honey production. The center hosts the African Reference Laboratory for Bee Health, the first laboratory of its kind in sub-Saharan Africa that centers on insect ...
Insects have spiracles on their exoskeletons to allow air to enter the trachea. [1] [page needed] In insects, the tracheal tubes primarily deliver oxygen directly into the insects' tissues. The spiracles can be opened and closed in an efficient manner to reduce water loss. This is done by contracting closer muscles surrounding the spiracle.
Entomology (from Ancient Greek ἔντομον (entomon) 'insect' and -λογία 'study') [1] is the branch of zoology that focuses on insects. Those who study entomology are known as entomologists. Those who study entomology are known as entomologists.
The discipline of medical entomology, or public health entomology, and also veterinary entomology is focused upon insects and arthropods that impact human health. Veterinary entomology is included in this category, because many animal diseases can "jump species" and become a human health threat, for example, bovine encephalitis.
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.
Insect cooking oil, insect butter and fatty alcohols can be made from such insects as the superworm (Zophobas morio). [199] Insect species including the black soldier fly or the housefly in their maggot forms, and beetle larvae such as mealworms , can be processed and used as feed for farmed animals including chicken, fish and pigs.

Anautogeny and consequent blood-feeding is seen mainly among the dipteran insects, including mosquitoes, black flies, sand flies, horse flies, and biting midges.Most anautogenous dipterans possess sharp, blade-like mandibles for extracting blood, though these mouthparts are often underdeveloped in the male.
