Yes, I have done 10 th's this way, mostly of very small moths (Nepticulidae).
The protocol was developed by Sonja Knölke, Andreas Segerer and others in Munich. A paper (Knölke et al) is in press in Insect Systematics and Evolution, as far as I know not yet published. They suggest that this should be standard procedure! 
If you want the detailed protocol I think you should contact Andreas Andreas.Segerer at 

The results are good: enough DNA extracted and perfectly clean genitalia!

Hello All,

Has anyone experimented with using a proteinase-K/buffer solution to clear insect abdomens for genitalia preparation, rather than using 10% KOH?  Seems to me this would allow you to extract DNA from the gunk that one normally throws out...  If you have tried this yourself or know of references please e-mail me.
