Residual toxicity of some fluoroaliphatic sulfones to the red imported fire ant, solenopsis invicta (Hymenoptera: Formicidae)

Thirty-six fluoroaliphatic sulfones were tested to determine their residual toxicity to Solenopsis invicta Buren in soil. Six of the compounds gave >90% kill of the ants after they were exposed for 4 days at 10 ppm. When tested at 1.0 ppm, only one compound, AI3-10841, gave appreciable mortality....

Description
Summary:Thirty-six fluoroaliphatic sulfones were tested to determine their residual toxicity to Solenopsis invicta Buren in soil. Six of the compounds gave >90% kill of the ants after they were exposed for 4 days at 10 ppm. When tested at 1.0 ppm, only one compound, AI3-10841, gave appreciable mortality. This compound was tested at 10 ppm in soil held outdoors under ambient summer conditions. Mortality 8 days following initial exposure to samples of this soil was 100% for 12 wks and 91 to 100% from 20 to 36 wks. /// Treinta y seis fluoroaliphatic sulfones fueron examinados para determinar su residúo tóxico a Solenopsis invicta Buren en la tierra. Seis de los compuestos químicos dieron >90% de mortalidad de las hormigas después de 4 dias de exposicion a 10 ppm. Cuando tratadas a 1.0 ppm, solo un compuesto, AI3-10841, dió motalidad apreciable. Este compuesto fue examinado a 10 ppm en tierra mantenida al ambiente libre durante el verano. La mortalidad 8 dias después de la exposición initial a muestras de esta tierra fue 100% por 12 semanas y 91 a 100% de 20 a 36 semanas.
