Résumé en Espagnol – Anglais – Turc
The diversity of insects serves a sustainable ecosystem and generally responds to the structure of the landscape. Many families of the order Hymenoptera contribute to the regulation of pests and pollination. Different families of the order Neuroptera fight against pests and family. Syrphidae has an important role in pollination. In this work, the abundance and diversity of the different Hymenoptera families and their relationship with the structure of the landscape have been studied. On the other hand, it has been studied about the abundance of the neptera and dipterous syphilids pollinators. The tree canopy was sampled in 15 olive groves in the southeast of Madrid. In each olive grove, four chromotropic traps were placed for a week and four samplings were made between June and September 2016. A total of 31.452 Hymenoptera belonging to 43 families were captured. Hymenoptera parasitoids were more abundant (76.9%), followed by predators (21.4%) and pollinators (1.7%). The most abundant families were Scelionidae and Encyrtidae. In the predators, the most abundant families were Crabronidae and Vespidae. In the case of pollinators, the Halictidae family was more abundant. Within the order Neuroptera, the most abundant family was Coniopterygidae (61.7%), followed by Chrysopidae (37%) and Hemerobiidae (1.3%). The family Syrphidae (28.5%) was the second family within the pollinators belonging to two orders. Hymenoptera showed variable behavior in relation to the surrounding landscape for different families. In some cases, the abundance was related to the complexity of the landscape, as for example in the case of the family Crabronidae. However, the great part of the families, their abundance showed no relationship with the structure of the landscape or was greater in simple landscape contexts. Therefore, the results indicate that the olive grove is the main habitat of many important orders and contributes to maintaining the biodiversity of these important insect orders.
