termisiä

Termisiä is a Finnish-language term that refers to termites, a group of eusocial insects known for their wood-destroying feeding habits and their role as decomposers in many ecosystems. In biological classification, termites are part of the order Blattodea and the infraorder Termitoidea. They are commonly divided into lower termites and higher termites, with higher termites belonging to the family Termitidae. Termite colonies are organized into castes, typically including workers, soldiers, and reproductives, with a primary queen and king driving reproduction. Colony sizes can range from thousands to millions of individuals, depending on species and habitat. Termites feed primarily on cellulose from wood, leaf litter, and plant fibers, assisted by symbiotic bacteria and protozoa in their guts that digest cellulose.

Termites construct nests and, in many tropical species, large earthen mounds that help regulate temperature and humidity. Subterranean termites live mainly in soil and require contact with the ground, while dry-wood termites infest wood above ground without soil contact. Foraging behavior is coordinated within the colony through chemical signals, tactile cues, and vibrations. Reproduction often occurs via winged alates during swarming, followed by pair formation and colony founding.

Human interactions include ecological benefits as nutrient recyclers, but many termite species are significant pests with the potential to damage buildings, furniture, and crops. Management typically relies on integrated pest management strategies, including moisture control, physical barriers, bait systems, and carefully applied termiticides.
