Natural and human-made disasters such as floods and logging occur in and around rivers. Stream-dwelling
aquatic insects respond to these disturbances in various ways. Primary consumers among them rely greatly
on algae and leaf litter from riparian vegetation as food. Therefore, once a disturbance such as a flood has
occurred, insects may find it difficult to find food in a stream, and the aquatic insect assemblage can be
impacted greatly as a result. Disturbances in riparian areas also increase fine sediment loads into streams,
damaging habitat and altering the aquatic insect assemblage. Deforestation impacts not only terrestrial but
also aquatic animals. In this review paper, aquatic insect assemblages are assessed according to alterations
in land use in and around streams. Following this paper, it is expected that clarification of aquatic insect
fauna and their life cycles will progress and that the distribution and habitat use of aquatic insects will be
afforded greater attention in forest management.
