Resumen:
As urbanization continues growing, green roofs design emerges as a promising alternative toenhance plants and animals within cities. The scarce evidence available, nevertheless, gives noclear advantage of plants? origin on insect abundance. By using an experimental approach wherethe origin of the plant species (native-exotic) was manipulated across an urbanization gradient, weevaluated their efficiency as surrogate habitats for insects in Cordoba city, central Argentina. To doso we installed, in each of 30 houses, two blocks of a modular extensive green roof system (3m each), with either native or exotic plant species (6 species each). In March 2019 we used panyellow traps to sample insects, whereas the level of urbanization of each house was estimated byusing NDVI and surface temperature in a buffer of 400m. A total of 9024 insects from 10taxonomic orders were registered, being Diptera (40%), Hymenoptera (21%), Hemiptera (21%) andThysanoptera (14%) the dominant groups. We found a significant effect (χ2 =11.58; p
