Outline of Final Research Achievements

The impacts of two systemic insecticides, fipronil and imidacloprid, on aquatic organisms especialy two paddy dependent dragonflies, Sympetrum frequens and Orthetrum albistylum speciosum, was investigated on experimental rice paddy fields. Concentrations of these insecticides in the paddy water were reduced to the limit of detection as time proceeds. However, residuals of these insecticides in the paddy soil were detected even next year. Although both insecticides affect on both dragonfly species, the degree and pattern of these were different between two insecticides.
