Antagonist effects of the leek Allium porrum as a companion plant on aphid host plant colonization

Abstract Combining a non-host plant (companion plant or CP) with a target cultivated plant is considered as a promising strategy to reduce pest pressure. Among the companion plants (CP) commonly used in integrated systems, those belonging to the Amaryllidaceae family (chives, garlic, onion, leek) ex...
