Abstract:The neurotoxic insecticide class of neonicotinoids has become one of the most widely used groups of insecticides in recent years. They exhibit long half-lives and have the potential to linger in the environment and affect arthropod communities long after application. Many studies have looked at the effects neonicotinoids have on arthropod communities in a lab setting, however comparatively few studies have looked at arthropod communities and neonicotinoid contamination in restored prairie habitats. This study was aimed towards better understanding the impact of the common neonicotinoid clothianidin, on native bee and beetle communities in restored prairie settings. For native bees, we found that nesting probability and nesting abundance increased in sites contaminated with clothianidin. Conversely, we did not see differences in beetle family assemblages between clothianidin contaminated and control sites; however, beetle feeding guild abundances and trophic interactions between feeding guilds were influenced by clothianidin contamination. These results suggest that neonicotinoid contamination of natural habitats can have a number of environmental consequences for arthropods and that these effects are not always consistent between taxa or feeding guild. Further trophic interactions between beetle feeding guilds in conjunction with clothianidin are discussed, as well as implications of clothianidin contamination on both bees and beetles in prairie restorations.
