Resumen:
Ivermectin (IVM) is an antiparasitic extensively employed in cattlebreeding for decades. It can reach aquatic ecosystems and produce negativeeffects on non-target organisms. So, the aim was to evaluate the effects onsurvival and behaviour of a commercial formulation of IVM on Physalaemussantafecinus larvae. Behavioural parameters were assessed at 72 h and 96 h.The 96h-LC50 was 3.48 μg/L decreasing significantly to 0.74 μg/L at 120 h.The Risk Quotient for IVM was 167.56 at 120 h, which indicates the highenvironmental risk. At 72 h of exposure, only the 100 μg/L IVM concentrationproduced alterations on the behavioural parameters such as swim speed and distance, and the exploration and mobility rate, while at 96 h, even the lowestconcentration (1 μg/L) altered some parameters. The lethal and behaviouraleffects were time dependent. Ivermectin was highly toxic to P. santafecinuslarvae, causing alterations on their behaviour at acute exposure times andlethality at environmentally relevant concentrations.
