  • In the study of population dynamics of non-biting midges (Diptera: Chironomidae) emerging from reclaimed rice fields in Seosan, Chungchongnam-do, Korea, a new species, Tanytarsus seosanensis sp. nov. and an unrecorded species from Korea, Chironomus javonus (Kieffer) were found. T.seosonensis was the third dominant species among the non-biting midges found in the reclaimed rice fields, whereas C.javanus was a rare species. They are fully described with illustrations.

  • To recognize the species composition and community of chironomid midge in agroecosystem and evaluate removal capacity of organic matter using the dominant species among them. Chironomid midge and invertebrate cohabitants were quantitatively collected at 78 representative stations of five habitat types (in arable land during 2004$\sim$2006) A, paddy fields of the large scale arable land; B, paddy fields of the environmental friendly arable land; C, influent of domestic waste water; D, influent of waste water by livestock; E, the irrigation ditch of paddy area. The total sixteen species of chironomid midges at arable land were presented. And also chironomid midges were recognized by five habitat types: eleven species in D, eight in A, seven in E, six in B, and two in C. We confirmed dominant species in each habitat types as followings: Chironomus nipponensis in A, C, and D; Cricotopus sylvestris in E; Tanytarsus seosanensis in B. Water quality and community index were high in E, but low in A, B, C, and D. Comparing with non-treatment, removal activities of organic matter in bottom by C. nipponensis were increased 18% in 90 individuals treatment.
