It was investigated the biocomplexof European corn borer larva parasite in the locality of Backa Palanka (Yugoslavia). When the experimental plants reached the full i.e. technical naturity they were collected, counted and kept in boundles in natural conditions till the beginning of winter. After that in laboratory was made the examination and disection of plant. For experiment were used 8 species of breeded plants and the same number of spontaneous flora. The next conclusions were : The number of European corn borer larva parasite was the greatest on species which had the most density host population. There was correlation between population density of European corn borer and its parasite. At some weed species the parasitism of some larvas was absent during some years. Also, when it appeared it was only in a small percent. In corn plant parasities were presented in all years of experimentation. They were effective in decreasing European corn borer population. In parasiting European corn borer larvas mostly were presented 2 and 3 types of parasite. In parasiting European corn borer larvas which were growing on experimental plants were 4 types of parasite: Lydella thompsoni Hrt., Camploplex alkae Ell., Horogenes punctorius Roman and Eulophus viridulus Thoms.
