title: Teratological examination of Wofatox 50 EC (50% methylparathion) on pheasant embryos.
abstract: Wofatox 50 EC is a widely used experimental insecticide, which can expose the pheasants (non-target organisms) during the plant protection practice. The test material was employed in 4 different aqueous emulsions, of which the 2 lowest level (0.2 and 0.4%) corresponded to the concentrations used in plant protection. The total volume of injected emulsions was 0.1 ml per egg on the 12th d of incubation. The macroscopic results showed a dose-dependent maldevelopment (generally cervical lordosis and scoliosis, cyllosis and sporadic thoraco-gastroschisis).
