"Immediate and short-term consequences of trials upon selected non-target organisms were studied. Phosphamidon employed as a larvacide at dosage rates in excess of 0.140 kg AI/ha proved to be harmful to the small forest bird complex but did not affect this group when applied as a budworm adulticide in multiple applications of 0.070 kg AI/ha. Aquatic organisms in streams and native small mammals were not affected by the phosphamidon trials. Acephate and carbaryl did not affect birds when applied as a larvacide at varying dosage rates. Aminocarb applied as an adulticide did not cause any mortality to the avian complex or affect benthic organisms in a test stream. Four operational blocks treated with two applications of fenitrothion at the emitted dosage rate of 0.210 kg AI/ha were monitored. Breeding bird populations were not affected but variations in age, class structure and sex ratio of Clethrionomys gapperi (Vigors) were recorded. Benthic organisms in a fenitrothion treated stream decreased after the first application but showed partial recovery after the second application"--Abstract. Includes abstracts in French and English.
