This study investigated the population dynamics and the phenology of Lobesia botrana (Denis & Schiffermüller, 1775) feeding on Daphne gnidium L. (Malvales, Thymelaeaceae) in the San Rossore-Migliarino-Massaciuccoli Nature Reserve (Tuscany, Italy). Four species of egg parasitoids of the genus Trichogramma spp were obtained. The parasitization rate gradually increased over the season, reaching its maximum level in September 2015, with a percentage of parasitized eggs close to 55%. Three of the species obtained were already known as L. botrana parasitoids , whereas the finding of Trichogramma cordubense Vargas & Cabello, 1985 represents the first recording in Italy, as well as the first report of this species among the natural enemies of L. botrana.
The first record in Italy of Trichogramma cordubense Vargas & Cabello 1985 (Hymenoptera Trichogrammatidae) emerging from the eggs of Lobesia botrana (Denis & Schiffermüller, 1775) (Lepidoptera Tortricidae).

Abstract
This study investigated the population dynamics and the phenology of Lobesia botrana (Denis & Schiffermüller, 1775) feeding on Daphne gnidium L. (Malvales, Thymelaeaceae) in the San Rossore-Migliarino-Massaciuccoli Nature Reserve (Tuscany, Italy). Four species of egg parasitoids of the genus Trichogramma spp were obtained. The parasitization rate gradually increased over the season, reaching its maximum level in September 2015, with a percentage of parasitized eggs close to 55%. Three of the species obtained were already known as L. botrana parasitoids , whereas the finding of Trichogramma cordubense Vargas & Cabello, 1985 represents the first recording in Italy, as well as the first report of this species among the natural enemies of L. botrana.File | Dimensione | Formato | |
