"The flicker fusion frequencies (FFFs) of six laboratory insects, and the response of the compound eye to mains fluorescent ‘ripple’" (Miall, 1978) touches on the FFFs for six different insect species commonly used in laboratory settings:

Locusta migratoria, Periplaneta americana, Saturnia pavonia, Antheraea pernyi, Glossina morsitans and Drosophila hydei.

I also found this paper: Potential Biological and Ecological Effects of Flickering Artificial Light (Boyles, 2014) that includes an exhaustive literature search of flicker-fusion thresholds and other related data for many species (including insects). If you're looking for an authoritative source, I'd say that this is it (as there doesn't seem to be a database with this information).
