Abstract

Dasineura oleae was considered a minor pest in olive orchards. However, in the last decade, outbreaks have been reported all over its distribution area. Little is known about D. oleae biological control strategies; therefore, investigations into the biology and ecology of D. oleae parasitoids are urgently needed. In this scenario, the present field study reported the flight period of D. oleae parasitoids, evaluating their relative abundance over other parasitoids living in olive orchards. Furthermore, it estimated the effect of local and landscape features on D. oleae parasitoids within the frame of the overall parasitoid community. Lastly, we aimed to provide useful insights into the effectiveness of parasitoids for D. oleae population management. Hymenopteran parasitoids were sampled using Malaise traps in six sampling sites in central Italy. Results showed that Platygaster demades was the most abundant D. oleae parasitoid. Its presence was associated with high rates of D. oleae parasitism. The abundance of this parasitoid was influenced by the abundance of seminatural habitats.
