Parasitoid assemblage size and host ranges in a parasitoid (Hymenoptera)-agromyzid (Diptera) system from central Argentina

A parasitoid community on agromyzid leaf miners from Cordoba, Argentina was analysed in terms of parasitoid assemblage size and host ranges of parasit oid species. Samples were taken during 1991-1995 at natural, urban and agri cultural habitats. The system consisted of 69 parasitoid species and 51 lea f miner species on 109 plant species. On average, 12 species parasitized ea ch host, when only numerically well represented leafminer species were cons idered for analysis, Each parasitoid species exploited on average seven spe cies and three genera of agromyzid leafminers. Both parasitoid assemblage s ize and parasitoid host range were notably high when compared with similar systems from other regions.
