We quantitatively collected chironomid larvae from samples of the 4 species of angiosperms present in the lakes: the emergent plants phragmites australis (a reed) and Zizani latifolia; the floating plant Nymphoides peltata; and the submerged plant Potamogeton malaianus. Collections were made from all 4 plant zones in Lake Suwa from April 2000 to November 2000 and from the reed zone in Lake Kitaura from April 2000 to March 2001. In both lakes the most abundant chironomid Larvae on the reed stems from late May to September were Chironominae (especially, Dicrotendipes pelochloris and Glyptotendipes tokunagai). On the leaves of submerged and floating plants in Lake Suwa, Orthocladinae larvae (especially, Cricotopus trifasciatus) dominated during the sampling period. On the reed stems in Lake Suwa, mean larval density was 0.4 ind cm\u207b\u00b2 and biomass of epiphytic chironomids was 12.9\u03bcgcm\u207b\u00b2; these values were 23% and 22%, respectively, of those in Lake Kitaura.

内容記述タイプ Abstract
内容記述 We studied the population dynamics of epriphytic chironomid larvae in the vegetated areas of Lakes Suwa and Kitaura. We quantitatively collected chironomid larvae from samples of the 4 species of angiosperms present in the lakes: the emergent plants phragmites australis (a reed) and Zizani latifolia; the floating plant Nymphoides peltata; and the submerged plant Potamogeton malaianus. Collections were made from all 4 plant zones in Lake Suwa from April 2000 to November 2000 and from the reed zone in Lake Kitaura from April 2000 to March 2001. In both lakes the most abundant chironomid Larvae on the reed stems from late May to September were Chironominae (especially, Dicrotendipes pelochloris and Glyptotendipes tokunagai). On the leaves of submerged and floating plants in Lake Suwa, Orthocladinae larvae (especially, Cricotopus trifasciatus) dominated during the sampling period. On the reed stems in Lake Suwa, mean larval density was 0.4 ind cm⁻² and biomass of epiphytic chironomids was 12.9μgcm⁻²; these values were 23% and 22%, respectively, of those in Lake Kitaura. The differences in chironomid abundance observed in the lakes seemed to be caused by differenes in food availability (i.e., abundance of algae attached to reed stem). The average of diversity index (1/λ,λ:Simpson's index) of chironomid larvae on each plant was 2.7-3.3 on reed and Z.latifolia. 1.8 on N. Peltata and 1.8 on P. malaianus from June to August. The differnces in diversity index may be correlated with the conditions of DO concentration during this period.
