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 ...

Climate change and the introduction of exotic species that compete with the indigenous ones put the native species under stress, and as a result they are more likely to succumb to pathogens and parasites. [6] As of 2017, at least 66 insect species extinctions had been recorded in the previous 500 years, which generally occurred on oceanic ...
Handbooks for the Identification of British Insects is a series of books produced by the Royal Entomological Society (RES). The aim of the Handbooks is to provide illustrated identification keys to the insects of Britain, together with concise morphological, biological and distributional information.
The insect-symbiont interactions generate morphological adaptations and mechanism that insects use to protect, nourish, and transport their microbial partners. Examples include fermentation chambers, bucal pockets, blind sacs, crypt guts, diverticula, crypt cells, bacteriocytes, mycetocytes, and mycetomes, as well as instances where bacterial ...
In insects, tympanal organs are used to hear distant sounds. They are located either on the head or elsewhere, depending on the insect family. [25] The tympanal organs of some insects are extremely sensitive, offering acute hearing beyond that of most other animals. The female cricket fly Ormia ochracea has tympanal organs on each side of her ...
