Hi fellows. Does any one here protect his caprifig (plants and fruits) in the frosty winter and in the boiling summer - because the Blastophaga may be killed under such conditions. Do you have any data- personal or written about this issue - how to protect and preserve the caprifig wasps? and control their release?

They certainly need winter protection, and it would be best if the lows don't dip below freezing whatsoever and preferably not below 40 degrees F. I wouldn't imagine there is much need to protect against heat, Blastophaga exists in some super hot climates (e.g. North Africa, Middle East) so I imagine water stress could be a potential issue but anything the figs can tolerate I imagine the wasps can too due to their inherent co-existence 

Just making sure that you know, most of the fig varieties members grow here (Common Figs) do not require any pollination for successful fruit-set

Hi fellows I know you aremostly commons. My caprification experiment was planned as to get a. all Smyrnas to set fruits, b. over-extra pollination even of commons may boost crops, c. pollinated fruits do not drop as fast non pollinated commons. d. The dreadful black fig fruit fly is my major enemy 24/7. Research report here showed that pollinated figs (including commons) are tolerant to this enemy-pest by 99%. This research is based on finding certain compounds emmited by the fruit when pollinated or not. In my case 100% of the fruits of all typws even of caprifigs drop because of this BlacK Fig Fruit Fly. It is a challenge to combat it and not kill the good wasps by sprays, sticky yellow sheets etc

Hello Ariel
Welcome to the forum
In  your Land IMO there will be no particular worries to protect the Caprifig.
Are your trees 'in ground' or pots. ?? Saw your weather averages and it's sort of ideal for any fig cultivation, Caprifigs included... Occasional freezing temps in Jan/Feb (down to -3 or -4ºC) are not a problem for Caprifigs.. where I have seen a few problems is when unexpected and accidental  'heat waves' arrive during  April/May with temps going up to.. 35++ºC. The more sun exposed fruit abort, only the  shaded Profichis  will survive. If your figs are potted you shall have to be previously  alerted and somehow protect them under the shade from other trees.
