EXPOSURE TO A COMMON ANTIHISTAMINE DOES NOT STRONGLY INFLUENCE PREDATOR-PREY INTERACTIONS IN LARVAL ODONATES
Analyses of surface water have documented the presence of trace amounts of many pharmaceutical and personal care products (PPCPs). While some studies have determined the toxicity of some PPCPs to model organisms in the laboratory, ecotoxicologists are only beginning to consider the effects of these compounds on communities and ecosystems. We examined the effects of an antihistamine (fexofenadine) on predator-prey interactions between nymphs of the dragonfly Anax junius and the damselfly Ischnura verticalis. We expected that exposure to fexofenadine would reduce activity levels of both A. junius and I. verticalis resulting in fewer predator-prey interactions and promoting prey survival. Both were exposed to the presence/absence of fexofenadine for 24 hours in a factorial treatment design. Each predation trial included 1 A. junius and 10 I. verticalis, lasted two hours, and was recorded on video. There were no significant effects of fexofenadine exposure on Ischnura survival or Anax behavior. Studies such as this further our understanding of the effects of pharmaceuticals on aquatic insects. Future studies should how exposure duration influences behavior.
