Reproduction by an altricial songbird, the red-winged blackbird, in fields treated with the organophosphate insecticide fenthion Reproduction by an altricial songbird, the red-winged blackbird, in fields treated with the organophosphate insecticide fenthion
(1) Breeding red-winged blackbirds were used as a model to study the effects of a single application of an organophosphate insecticide, fenthion, on reproduction of altricial songbirds. (2) The insecticide had no significant effect on frequency of nest abandonment, clutch size, hatching success, or fledgling success. (3) Growth rates of young nestlings were lower in nests on one of two...

Comparative toxicity of acephate in laboratory mice, white-footed mice, and meadow voles Comparative toxicity of acephate in laboratory mice, white-footed mice, and meadow voles
The LD50 (95% confidence limits) of the organophosphorus insecticide acephate was estimated to be 351, 380, and 321 mg/kg (295–416, 280–516, and 266–388 mg/kg) for CD-1 laboratory mice (Mus musculus), white-footed mice (Peromyscus leucopus noveboracensis), and meadow voles (Microtus pennsylvanicus), respectively. In a second study, these species were provided mash containing 0, 25, 100...
