Google Scholar is an ok tool for research but you'll get better results in less time if you learn how use advanced databases (like those linked on this page). They're not that hard to use and as long as the database is a good match for your topic, you should get better results.
This page contains links to scholarly databases which will help you locate research articles related to entomology. If you are not sure where to start try one of the General Purpose databases such as Scopus or Google Scholar before jumping into one of the more specialized databases.
Scholarly databases contain journal articles, book chapters, conference proceedings, meeting reports, and more.
