One thing I often check is who the author(s) are and what their links to industry might be. For example if the paper claims that "Smoking is good for you in moderation" and then after googling the author I find they have ties to Marlboro I start to doubt the authenticity of the research.
In this case the authors are mostly organizations that from what I can tell do not have any affiliation with for example an insecticide company or even a company. The only non organization author I see listed is Michael S. Crossley. I googled him and did not find anything suspicious. He does not appear to have a background in entomology or ecology. I am not really sure if that is reason to be suspicious but just thought I would share.
Here is a link about one of the authors: http://www.bristol.ac.uk/education/people/michael-w-crossley...
