Effects of Plant Stress and Habitat Manipulation on Aphid Control in Greenhouse Sweet Peppers

Interactions between sweet pepper, aphids, and natural enemies under greenhouses can be modified by management practices. An excess of salinity in the irrigation of sweet pepper, the effect of flowering plants on aphid density, and natural enemy diversity were evaluated. Aphids were more abundant on...

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