what do you mean by “larger concern”?!? are you implying the insect-decline is just bad science, or is this sarcasm? the mentioned papers assumption for it may be deadwrong, not the fact of the declining itself.
myles power did a good video on the topic and he doesnt denies the declining in the slighest, just says the paper itself is extremly sloppy and seems BS:
edit/ oh, thats from 2014?!? I thought you meant that new paper 
and just as reminder; article and video are talking “managed beehives” here, not wildbees and insects in general.
