We know brand new limits of the study: particularly, merely county-top quotes have been given regarding the USGS dataset and you can extrapolation tips were used so you can estimate pesticide have fun with for the majority of areas. On SSA, i noted that people could have together with analyzed brand new style for the usage of several other chemical compounds, but centered merely to the about three widely used neonicotinoids, as they represent a category off chemical substances which were implicated throughout the refuse off bees. We are going to still comment and you may evaluate the the means to access individuals chemical substances and affects to the rusty patched bumble-bee through the healing thought.

They advise that new lowering of rusty patched bumble bee communities preceded the fresh new prevalent entry to neonicotinoids within the diversity, and therefore the fresh bees is persisting from inside the locations with prevalent neonicotinoid use to the corn and you can soybeans
