Chris,
I do not know the current quarantine requirements. They have to be, I think, 100 feet (might be50') from other fig trees, which is not doable on small city lots if you or your neighbor has a fig tree. When I had my space inspected and approved several years ago it was sufficient distance, but don't remember the exact requirement. The State Ag person or the County Ag person will come out and inspect you quarantine area prior to the approval and issuance of the permit. They had to come and re-verify everything when I renewed a couple years ago. There was no requirement for any kind of structure, but you will probably need some sort of greenhouse to root the cuttings in.
They were quarantined for a minimum of 2 years, were inspected annually, and, in my case, it too about 2-1/2 years because they arrived in February, so two years latere they were in a dormant mode. The final inspection has to be done when they are leafed out, so it was May before they could do the final inspection. If I remember correctly, a CDFA (CA Dept Food and Agriculture) person did the final inspection, filed the results with the County Ah Dept, which forwards it to the State Dept, which forwards it to the USDA for final disposition.
Until you receive a final release, they are NOT you cuttings or plants. They are the property of the USDA, which "subcontracts" out their care to you. After final release, then they are your property. As long as they are the property of the USDA, you cannot take the plants or cuttings out of the quarantine area, and you must keep any plant material which dies, for the inspector. The fact that all plant material that is imported is technically the property of the USDA is, I suspect, the reason that they can come and take possession of it from your property. Your are essentially in illegal possession of their property.
Originally, I just had to list the countries that I expected to get cuttings from, and put a overall quantity that was sufficient to cover what I might, but not you have to list a quantity for each country and if you actually end up importing more, then you have to have the permit modified prior to shipment.
Information on the beetles is here: Federal Order There is a more recent update, in 2011, but couldn't find the location., and if you check the link below, there is a 2013 update, as well.
Here is the USDA Guidelines for importing plant material. See Table 2-7, 2-10, 2-11 If I am reading Table 2-10 correctly, the new rules are no ficus from Europe. Following this document will give you a headache.
