Abstract

Preliminary phylogeny of Encarsia Förster (Hymenoptera: Aphelinidae) based on morphology and 28S rDNA.

Abstract

Species of Encarsia are used as biological control agents of crop pests. Sequences of the D2 expansion region of 28S rDNA of 24 Encarsia species were used for phylogenetic analysis. The molecular data were evaluated separately and in combination with morphological data. All analyses that included molecular data revealed thatEncarsia was paraphyletic with Encarsiella. An alternative hypothesis, based on the constraint of monophyly of Encarsia, is presented. The luteola and strenua species groups are shown as monophyletic by both morphological and molecular data, while other species groups are supported only by molecular data.
