Apparently, the little bugger is "La Cochinilla"...and is easily cured!More to come.

the cochinillas live on the sap of the tree, particurarly from the new buds or shoots... it is possible to be erradicated with a systemic plaguicide like dimetoato (or cypermectines).
Don´t know any brand or way of applying it, except that it is not by spraying the tree.
They can kill the trees very easily specially if no phitosanitary control is planned (as I think it isn´t in Buenos Aires....... BUT IT IS IN THE CITY OF LA PLATA!!!)
It is part of the duties of the porteño government:

Let´s all investigate some more...
MORE... and more and more...
There's a law :"1556/04 Regulación del Arbolado Publico Urbano" (its object is to protect, preserve and guard BsAS environment tru a rational policy of protection to urban public trees).
This law led to a Public Trees Master Plan ("Plan Maestro del Arbolado Público") - at the "Programa Biodiversidad Urbana" office (Cerrito 268 12#;4010-0300 int.13143; paisaje@buenosaires.gov.ar)
Soooooooooo... Our beloved trees, jacarandas and any other one in the city are under the watch of the following people:

OK, now that we know who should be taking care of such a simple thing as killing bugs, what are we going to do?
I suggest:
1st.: adopt the very first one you see, maybe the one in front of your house or block (by the way, the bsas gov actually did a good job in mapping them -you can search names etc etc etc at:
www.buenosaires.gov.ar/areas/med_ambiente/
Arbolado/?menu_id=19562 )
2nd.: call, write, bother these people in your own language until something is done
any other suggestions???
yep, again me...
check this portal, is great!

It seems that TIPAS are also in danger. These are MY favorite trees, sorry YanquiMike.
I´m talking about those ones that are spreading their little yellow flowers right now on the Good Airs of Buenos Aires ;)
People from a neighborhood organization
(http://holaparquechacabuco.wordpress.com/) are joining to save them from some other bicho (la chicharrita)

I am so glad to have learned what is bothering the trees. If someone is able to tell me the name of what to buy and how to apply it to the trees, I will be happy to treat all of the trees on my street.
As soon as I know I'm publishing it!
Next week I'm going to a nursery to investigate more...
But I still think that all the necessary resources for an overall treatment are out there, at the gov hands and we should insist on that too.
All I'm saying is to pursue the personal care for these creatures and at the same time to erradicate the problem with the public tools...
Could someone please tell me where I can buy Jacaranda trees?

that scale insect on the jacaranda well i dont really know if the local common name for the insect, la cochinilla, is just a nickname for a similar colored insect but there is a scale insect that can produce and important dye for fabric cochineal
look it up in wikipedia from wiki the start......much more info.. Cochineal is the name of both crimson or carmine dye and the cochineal insect (Dactylopius coccus), a scale insect in the suborder Sternorrhyncha, from which the dye is derived. There are other species in the genus Dactylopius which can be used to produce cochineal extract, but they are extremely difficult to distinguish from D. coccus, even for expert taxonomists, and the latter scientific name (and the use of the term "cochineal insect") is therefore commonly used when one is actually referring to other biological species; suffice it to say that the reader should be aware that there is more than one cochineal insect. The primary biological distinctions between species are minor differences in host plant preferences, in addition to very different geographic distributions. D. coccus itself is native to tropical and subtropical South America and Mexico.
This type of insect, a primarily sessile parasite, lives on cacti from the genus Opuntia, feeding on moisture and nutrients in the cacti. The insect produces carminic acid which deters predation by other insects. Carminic acid can be extracted from the insect's body and eggs to make the dye. Cochineal is primarily used as a food colouring and for cosmetics. david
