As this links to a paid publication by Elsevier, I can't say anything about it. I can, however, link to another article, only months ago, and it's debunking (latter in Dutch, sorry) https://ancillary-proxy.atarimworker.io?url=https%3A%2F%2Fwww.theguardian.com%2Fenvironment%2F2017%2Foct%2F18%2Fwarning-of-ecological-armageddon-after-dramatic-plunge-in-insect-numbers and https://ancillary-proxy.atarimworker.io?url=https%3A%2F%2Fwww.nemokennislink.nl%2Fpublicaties%2Fernstige-zwakheden-in-alarmerend-onderzoek-naar-vliegende-insecten%2F
As said, I can't say anything about the Elsevier article and frankly, I don't think it serves a purpose to link to articles we can't read. Thinking of it, this would make a great business model: perform research with alarming outcome; get paywalled article linked on Slashdot... Profit!
