Natural parasitism of predatory syrphids in horticultural crops

Description

Hoverflies contribute to ecosystem services as pollinators and aphid predators, yet their biological control potential can be compromised by natural enemies. We quantified larval parasitism of the predominant predatory hoverflies, Allograpta exotica and Toxomerus duplicatus, in broccoli and lettuce crops over three years in Argentina.
