Résumé / Abstract

Because the larvivorous fish Pseudomugil signifer is native to southeastern Queensland and is abundant in shallow estuarine habitats, intertidal marshes, wetland habitats, and freshwater streams, it was chosen as an indicator species for toxicologic studies with pesticides. Acute toxicity studies with 2 organophosphorus pesticides (pirimiphos-methyl and temephos) and 3 alternate compounds under evaluation for registration in Australia (Bacillus thuringiensis var. israelensis, s-methoprene, and pyriproxyfen), were tested in 96-h laboratory trials. Pirimiphos-methyl was the most toxic compound, with a median lethal concentration (LC50) of 0.091 ppm (0.3 times the estimated field concentration [EFC] for a 15-cm-deep pool). Temephos had an LC50 value of 0.594 ppm (9.9 times the EFC). Bacillus thuringiensis var. israelensis and pyriproxyfen produced LC50 values of 6.1 x 10 International Toxic Units (477 times the EFC) and 0.854 ppm (106 times the EFC), respectively. s-Methoprene was the least toxic compound, with no mortality recorded at 500 times the EFC.
