Interactions between sweet pepper, aphids, and natural enemies under greenhouses, can be modifiedby management practices. An excess of salinity in the irrigation of sweet pepper, and the effect offlowering plants on aphids density, and natural enemies diversity were evaluated. Aphids were moreabundant on plants irrigated with high conductivity solutions, and on sweet peppers without associatedflowering plants. Parasitoids and predators were more diverse and abundant in presence of floweringplants. Greenhouse horticultural management practices that avoid stress conditions by means ofcorrect irrigation, and increase local biodiversity with flowering plants, could improve aphid controlby enhancing abundance and diversity of natural enemies.
