Freshwater macroinvertebrates were comparatively sensitive to diazinon. Results of large-scale experimental stream studies showed that dose levels of 0.3 p,g diazinon/L caused a 5-8-fold reduction in emergence of mayflies and caddisflies within 3 weeks after 12 weeks, mayflies, damselflies, caddisflies, and amphipods were absent from benthic samples. Elevated (and catastrophic) drift of stream invertebrates was also documented in diazinon-treated streams, especially for amphipods, leeches, and snails. Short-term tests of 5-h duration with rotifers (Brachionus calyciflorus) show a 50% reduction in feeding rate on alga (Nannochloris oculata) at 14.2 mg/L, with long-term implications to population stability.
