(31) Comment: Multiple commenters recommended that the Solution use the U.S. Geological Questionnaire (USGS) National Pesticide Synthesis data to teach fashion such as the broadening application of neonicotinoids over time inside rusty patched bumble bee’s range.
Our Reaction: I used USGS National Pesticide Synthesis study to aid see the annual local trend regarding three neonicotinoids (imidacloprid, clothianidin, and you can thiamethoxam) in historical listing of the brand new rusty patched bumble-bee. We know the fresh constraints of the investigation: specifically, merely condition-height prices was offered about USGS dataset and extrapolation steps were utilized so you can guess pesticide use for some areas. Thus, we used these types of graphs simply to discern you’ll temporal correlations between bumble bee (and lots of species of butterfly) declines and you will neonicotinoid have fun with. Regarding SSA, we noted that we could have and additionally analyzed the latest styles in the entry to numerous other chemical compounds, but concentrated merely on about three popular neonicotinoids, while they represent a course out-of chemicals that happen to be implicated regarding decline out-of bees.
