Abstract

The organophosphorus insecticide fenthion was applied to experimental ponds and its effects on phyto- and zooplankton communities were analysed. The sensitivity to fenthion differed among cladoceran and rotiferan species according to the following order: Daphnia galeata > Monia micrura > Bosmina fatalis >/= Polyarthra trigla > Keratella valga. The results suggest that large zooplankton species tend to be more sensitive to fenthion than small ones, large cladocerans more sensitive than small cladocerans, and cladocerans more sensitive than rotifers. The application of fenthion induced an increase in the density of rotifers and phytoplankton. This was a secondary effect of the chemical, which directly depressed cladoceran populations and consequently released rotifers and phytoplankton from competition with, and grazing by cladocerans.
