Secondary production of chironomid communities in insecticide-treated and untreated headwater streams. Lugthart, G. Freshwater Biology, 1990. Paper abstract bibtex Annual production on non-Tanypodinae chironomids in three first order AppalachianMountain streams during a no-treatment year ranged from 1366 to 3636 mg/m2, while production of Tanypodinae chironomids ranged from 48 to 116 mg/m2. Production/biomass ratios ranged between 19 and 23 for non-Tanypodinae and from 6to 7 for Tanypodinae chironomids. Insecticide applications significantly lowered chironomid densities and biomass in the treated stream relative to the pretreatment year and reference stream. Annual production of non-Tanypodinae(703 mg/m2) and Tanypodinae (32 mg/m2) chironomids in the treated stream decreased by 64% and 67%. In the same year, production of non-Tanypodinae (2084 mg/m2) increased by 34% and production of Tanypodinae (96 mg/m2) by 57% in the reference stream.
