The phrases stated through Serge Kreiter in the course of the assembly spring to mind. they can list precisely the scenario of Acarology in Europe and on this planet: "I imagine that during many ecu international locations there are only a few complete time acarologists. it's very infrequent to have new positions to be had . . . . And public funds, from the ecu group but in addition from nationwide international locations, is particularly not easy to get if you are looking to paintings on mites . . . . may perhaps acarological institutions in Europe (Eur. A. Ac. and S. I. A. L. F) interact or, greater, get married?" So, the fourth symposium of the ecu Acarologists has not just been the social gathering to have an concept on which course the study is addressed this day, but in addition it mentioned the problems of our "scientific hranch". at the foundation of the shows and invited papers we had evidences of a "new" Acarology in keeping with glossy concepts and strategies of investigations but in addition the significance, usually sheltered whether of proper worth, of the "old" Acarology made at the alpha taxonomy and uncomplicated stories. So, a "new" Acarology wishes the "old" one. during this context, the desire to place jointly the eu acarologists has been bobbing up. This truth, of political that means, can without doubt enhance the acarological move and the dialogue in this aspect confirmed truly the significance of numerous different actions and efforts during this path. we are hoping that the assembly in Siena will signify a significative stone for the growth of Acarology.

Advances in molecular biology such as the polymerase chain reaction (PCR), efficient DNA sequencing and RNA interference now make it possible to take techniques developed on model organisms such as Drosophila and apply them to virtually any other taxon of interest.

He has described, together with Fain, the new species of Schwiebea codognoensis (Acari, Acaridae) living in aqueducts, studying also its relationships with other organisms living in the same habitat. Finally he has also taken into account the Ixodidae living in the urban areas and in the farms ascertaining the possibility of diffusion of such arthropods. 17 There are quite a number of scientists working on mites which are important from an agricultural point of view. Their aim is to get information on different species, both noxious and useful to crops, from different points of view, to deepen our knowledge on their biodiversity, their biology and behaviour, on the control of phytophagous species using biological methods and on the morphology and ultrastructure of species of some groups.
