Pyrethroid insecticides are widely detected in aquatic ecosystems due to their extensive use agriculture and horticulture, which could pose a potential risk non-target organisms. While previous ecotoxicological studies have been conducted mainly with standard tests local species under temperate conditions, scarce information is available on the effects of pyrethroid communities (sub-)tropical conditions.
