Biological control is currently being used in 100 ha of tunnel‐grown strawberry in northern Italy. Second‐instar larvae of Chrysoperla carnea are released (18 larvae per m 2 ) against aphids when more than 30% of leaflets are infested. Releases of Phytoseiulus persimilis (4–6 predatory mites per m 2 ) are also being used in IPM strategies against Tetranychus urticae ; wild P. persimilis populations also occur in the test area, which is near the Adriatic coast. Releases of predators are also successful in the field.
