Pollinator visitation between native and non-native plant species of southeastern U.S.

There are a number of studies examining pollination competition between native and non-native plant species.  Perhaps more important are interactions between native and non-native plant species, and their native and non-native pollinators.  These interactions enhance ecosystem services which is described as any positive benefit that wildlife or ecosystems provide to people.  Pollinators are critical to the success of agriculture.  How the European honey bee (Apis mellifera) interacts with native bees and other pollinators in the pollination of native and non-native plants is little understood.  In this study eight 3m3 plots were alternatively planted with native plants from southeastern U.S. and non-natives from Europe and Asia.  Plots were randomly sampled for pollinator visitation for 15 min each day over a month period during the summer of 2015.  Data was analyzed using the Likelihood Ratio Test (LRT) for goodness-of-fit between the native and non-native field plots.  Among the many insect visitors observed in the plots there were three predominant pollinators; the European honey bee (Apis mellifera), the American honey bee (Colletes hyalinus), and the American bumble bee (Bombus pennsylvanicus).  The abundance of the American honey bee on visitation to native and non-native plants favored the visitation of native plant species (p<0.00717) while the visitation of the European honey bee (p<0.1443) and the American bumble bee (p<0.1806) to native and non-native plants was not significantly different.  While the visitation rate of all pollinators between native and non-native plants was not significant (p<0.01229) there did appear to be a trend toward the visitation of native plants.  This trend needs to be examined future.  Continued important of pollinators to ecosystem services will be important to the future of agricultural productivity.
