Chironomid Midges Emerged from Aquatic Macrophytes in Reservoirs

Abstract

Chironomid fauna emerging from aquatic macrophytes in reservoirs was investigated in summer 1982 and 1983. Aquatic macrophytes surveyed were six species of floating-leaved and four species of submerged plants. Twelve genera, twenty-seven species and one tribe were identified. Pentapedilum tigrinum was largely collected from many plants. This species was more abundantly recovered from floating-leaved plants than submerged ones. Distinctive variations were observed in the number of species and the relative abundance among plants. Moreover, the seasonal variations of chironomid fauna living on leaves and stems of Nymphoides indica were also studied. Copyright © 1985, The Japanese Society of Limnology. All rights reserved.
