Insect ecology is the interaction of insects, individually or as a community, with the surrounding environment or ecosystem. [1] This interaction is mostly mediated by the secretion and detection of chemicals ( semiochemical ) in the environment by insects. [ 2 ]
Single-species insect conservation can preserve other species indirectly; this preservation-by-default is referred to as the umbrella effect. Showy insects such as butterflies or large, colourful beetles serve as flagship species, and can expand public awareness and financial contributions for conservation efforts. Wealthy nations such as the ...
Insects with population trends documented by the International Union for Conservation of Nature, for orders Collembola, Hymenoptera, Lepidoptera, Odonata, and Orthoptera. A 2020 meta-analysis found that globally terrestrial insects appear to be declining in abundance at a rate of about 9% per decade, while the abundance of freshwater insects appears to be increasing by 11% per decade.
Aquatic macroinvertebrates are insects in their nymph and larval stages, snails, worms, crayfish, and clams that spend at least part of their lives in water. These insects play a large role in freshwater ecosystems by recycling nutrients as well as providing food to higher trophic levels.
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.
Buforaniidae grasshoppers from the Australian National Insect Collection. The conservation and restoration of insect specimens is the process of caring for and preserving insects as a part of a collection. Conservation concerns begin at collection and continue through preparation, storage, examination, documentation, research and treatment when ...
Insects play many critical roles in ecosystems, including soil turning and aeration, dung burial, pest control, pollination and wildlife nutrition. [133] For instance, termites modify the environment around their nests, encouraging grass growth; [ 134 ] many beetles are scavengers ; dung beetles recycle biological materials into forms useful to ...
