Thank you all for commenting
Steve, these are Violeta figs, IMO the geographically distant brothers of Preto, Black Madeira,... but believed to be genetically very similar or even the same cultivar.
I have to say that I do not think these have been pollinated.. the reason being that this season, Profichis are not yet ripe.. Think they still need a week or two to effectively send out their wasp squadrons.
Last season by this day I had hundreds of pollen bearing wasps exiting the potted Caprifigs and pollinating receptive figs of all sorts at will.
To your question on the recommendation for experimenting 'in house' pollination you need to be sure that the figs (Common Smyrna San Pedro) are sufficiently developed and receptive to accept pollination by the time wasps exit the ripe Profichis.
It comes to my mind that you may try the hybrid DFIC0023, Zidi, Bournabat, Marabout/(Smyrna), Calimyrna, Desert King (2nd crop) Dauphine (2nd crop) Ice Crystal, ,... as well as many Common varieties, like Brown Turkey,Blk Mission, Kadota etc.
Suggest you to discuss this with Harvey, Igor, Sue,.. may be others in Cal. as there is already some years of accumulated experience with pollination in that State involving a great number of varieties.
