The paper aims to substantiate the need for Local Agenda 21 - The Local Strategy forSustainable Development by the systemic developing and the interdisciplinary treatment ofthe elements of Sustainable Development: economic, environmental, scientific-technologicaland social, of the strategic objectives proposed by citizens, in short, medium and long term,because it is not put into practice. These can be achieved by intercondition/interrelation,highlighting the compatibility/ incompatibility of the proposed objectives through the transfer ofmethodologies and concepts among different disciplines. We proposed the use of systemicmethods, participatory, prospective, antitheses, etc. The iterative scheme of theinterdisciplinary treatment is presented synoptically, as well as the effect of the impact on therelationship MAN - NATURE.THE ACTUAL STATUS OF THE WESTERN ROMANIAN PLAINFLORA AND VEGETATIONAurel ARDELEAN¹, Violeta TURCUŞ ²1 Title: Prof.,PhD, „Vasile Goldiş” Western University Arad, Honorary member ofAcademy of Romanian Scientists, Romania, rectorat@uvvg.ro2 PhD, „Vasile Goldiş” Western University Arad, Romania, violeta_buruiana@yahoo.comThe former afforested-marsh like character of this territory was profoundly modified dueto the increasingly powerful antropic pressure. Today, it is an excellent agricultural area,and the original semi - natural vegetation, is preserved only within some enclaves.Nevertheless, some sectors of the Western Plain – named also the Tisa’s Plain – presentlypreserve a remarkable flora and vegetation. Almost 2000 plant species were identifiedhere, to which about 200 hybrids can be added, as numerous intra-specific taxa.UTILIZATION OF BACULOVIRUSES IN DENSITYCONTROL OF LYMANTRIA DISPAR L. POPULATIONS(HAIRY CATERPILLAR OF OAK TREE)Mircea CIUHRII 11 Dr. Hab, Grand Officier in Inventics, Correspondent Member of Academy of RomanianScientists, General Manager of Research & Applicative Center “Insect Farm”, 100 ToamneiStreet, zip 020715 Bucharest, Romania, ciuhrii@insectfarm.comThe viral infections may be used for regulating the density of some undesired organisms,among which some insect species which compete with the man for food or materials. Inthe case of insects, there are used the Baculoviruses which are specific only for theinsects they are extracted from. So, the baculoviruses may be safely used to control thepopulation density of pests specific to some plants. In Romania we have implemented aviral preparation, “Inf-Ld”, infecting only the larvae of “hairy caterpillar of oak tree”(Lymantria dispar L.), the other components of biocenosis remaining unaffected andwithout any pollution of the environment.27
