Abstract

Systemic pesticides, such as the neonicotinoid imidacloprid, can be introduced into aquatic ecosystems through contaminated plant material, which is the basis for detrital (brown) aquatic food-webs. With the aim of exemplarily assessing for indirect effects on the level of predators, we first offered imidacloprid contaminated and uncontaminated alder leaves to the stonefly shredder Protonemura sp. for 72 h. Shredder survival, leaf decomposition, body length and biomass were all between 20% and 50% lower under imidacloprid exposure compared to uncontaminated conditions, indicating physiological implications. Subsequently, these shredders were provided as prey to stonefly predators (Isoperla sp.) kept in cages in a stream. Predator biomass and length decreased by up to 11% and 4.3%, respectively, when feeding on imidacloprid exposed prey. Our study hence suggests that plant material contaminated with systemic pesticides can exert adverse effects in aquatic predators when preying on shredders consuming such leaves, which warrants a further consideration of this pathway.

Additional information

Editor’s Note: The paper by Lima-Fernandes et al. that appears in this issue describes the results of a multi-tiered study designed to evaluate the effects of the systemic pesticide imidocloprid on stream-dwelling invertebrates. In this study, detritivorous stoneflies were fed imidacloprid-contaminated leaves from a previous study in a static laboratory exposure. Survivors were fed to predatory stoneflies housed in situ, which resulted in reduced predator biomass and length. The paper did not fully satisfy the requirements of BECT; it lacks adequate documentation of exposure concentrations, and control survival in the laboratory phase of the study was comparatively poor. It was nevertheless accepted as a “Concept Note” due to the novel nature of the study and because it calls attention to the potential hazards of systemic pesticides in detrital stream communities.
