Abstract
Fenitrothion injected into a stream at 73 μg/L diminished to 23 μg/L 343 m downstream and resulted in a decline of standing crop of benthic arthropods between 343 and 375 m downstream. Large and small insect larvae were not affected differentially. Most of the kill consisted of Leuctra spp. (Plecoptera: Leuctridae) larvae. Benthos recovery was complete 50 days after the treatment.This publication has 2 references indexed in Scilit:
