description

Abstract 1. Rotifers Brachionus calyciflorus were exposed to endosulfan and diazinon to determine the effect on nitration and ingestion rates. 2. The experiments were carried out with the algae Nannochloris oculata in a density of 5 × 105 cell/ml. 3. Rates of filtration and ingestion were decreased significantly at sublethal concentrations of pesticide tested after 5 hr exposure. 4. The effective concentration at which filtration and ingestion rates were reduced to 50% of those in controls ( ec 50) were calculated for both toxicants.
