Description Twelve South-Moravian vineyards were observed; three of them were protected by conventional chemical treatment, three by introduction of natural enemies of pests, three by bio-agents supplied by mild and restricted chemical intervention and three vineyards were abandoned to natural succession. Abundances of butterflies, beetles and birds were watched and relevant indeces of diversity and equitability were evaluated. Surprisingly, the greatest diversity was found on areas treated by integrated way not on the biologically treated ones. One possible conclusion is that the bio-diversity is influenced rather by the distance of agricultural area from natural surroundings than by an agriculture applied. Some data and analyses supported the idea was be presented. The second investigation was concerned with bio-diversity recovery (or decay) after massive chemical intervention. Data having reference to an evolution of insect abundances on two agricultural areas were collected and analyzed.
