What I can do with outliers that I got from ddRAD data?

Question

[mahnazkiani]

I am looking for some idea on data analysis of ddRAD data. I am interested to find SNPs associated with pesticide resistance in an insect that it's genome is not sequenced yet. I did several analysis related to genomic structure and also find some outliers based on Fst values. The data that I have coming from 7 susceptible populations and one resistant population. I did blast the outliers to NCBI, but didn't find anything intersting. I really appreciate if anyone can recommend me analsysi that can help me with this?

Thanks,
