Urbanization changes the composition of pollinating insect communities. But who are the winners and losers of this
environmental filter? Vincent Zaninotto and his collaborators attempt to answer this question in an article published
in the journal Insects, comparing the diversity of pollinators in natural environments and in Parisian green spaces.
Our results suggest that V. velutina is a generalist opportunistic predator targeting mostly locally abundant prey. While the species may have an impact on honeybees, its generalist, opportunistic behaviour on abundant insects suggests a minor impact on wild species.
A species of “murder hornet,” beheads and feeds to its larvae an insect that is very important to, and symbolic of, France: the honeybee.
In the city, the seasonal patterns of activity of insect pollinators could be disturbed by the urban microclimate as well as by the presence of ornamental flora. To study this phenomenon, Vincent Zaninotto and his collaborators monitored the activity of insect pollinators in Paris and in the natural environment, from late winter to autumn. In […]
