Diversité des Encyrtinae (Hymenoptera: Chalcidoidea, Encyrtidae) collectés par pièges Malaise au sein de la forêt de la Maâmora au Maroc


Abstract: The objective of this study is to characterize different parameters of the biodiversity of the Encyrtinae subfamily (parasitoids) collected by Malaise traps within the oak cork of Maâmora. The specimens were sampled once a week at three locations between June 2012 and May 2014. Quantitative analyzes identified 13 species and 12 genera belonging to 8 tribes. In addition, new data of genera and species were recorded for the first time in Morocco. The tribes containing a largest number of species are Aphicini and Habrolepidini (3). Metaphycus is the only genus represented by more than one species (2). Richness was estimated using nonparametric estimators: Chao 2, Jackknife 1 and Jackknife 2 with values of 48.4, 21.8 and 30.5, respectively. Diversity was calculated using the Shannon index, the equitability index and the Simpson index, and has the value 1.41, 0.55 and 0.54, respectively.
