Abstract

Kills of arthropods in three streams containing fenitrothion up to 6.38 ppb were measured using drift nets. Stoneflies and some species of mayflies were most affected. The drift responses of various taxa to the insecticide and to stream discharge are documented. The benthos was not seriously depleted.

Résumé

Des arthropods morts furent prit aux filets dans trois ruisseaux contenant du fenitrothion jusqu’au niveau 6,38 ppb. Des plécoptères et certains éphéméroptères étaient le plus touchés. L’auteur décrit les réactions des différents taxons à l’insecticide et au débit des ruisseaux. La faune du fond ne fut pas épuisée.
