The biological side-effects of fenitrothion in forest ecosystems / by C.H. Buckner. : Fo64-37/67-1974E-PDF
"Fenitrothion, applied as recommended for aerial control of forest insects in a single application of 3 oz/acre or in 2 applications of 2 oz/acre causes insect pest mortality for about 4-7 days. It degrades rapidly in water and soil, but may remain in trace amounts in certain plant foliage for several months. Although laboratory studies indicate that this insecticide is extremely toxic to honey bees, it causes no significant damage to commercial apiaries if applied as recommended. Forest amphibians are relatively insensitive to fenitrothion even at dosages several times the recommended level. Some species of small forest birds show slight mortality at applications above 4 oz/acre, and species in exposed niches such as yellowthroats, kinglets, Nashville and Tennessee warblers, and chipping sparrows show an increase in susceptability as dosages increase. Other spcies, notably the white-throated sparrow, are relatively insensitive to treatments even four times the recommended levels. Small mammals are less sensitive than birds. Shrews first indicate impact at dosages beyond 6 oz/acre and rodents react at levels beyond 15 oz/acre. It is concluded that this insecticide presents only negligible environmental impact if used as directed"--Abstract, page 1.
