Re-description and biocontrol information of Pauesia antennata (Mukerji) (Hym., Braconidae, Aphidiinae), parasitoid of Pteroschloroides persicae (CHol.) (Hom., Aphidoidea, Lachnidae)

Abstract

A survey was carried out on the distribution and seasonal occurrence of Pauesia antennata (Mukerji) in some provinces of Iran. P. antennata was the only specific parasitoid of the brown peach aphid, Ptewchloroides persicae (Chlor.) that occurred in all of the sampling areas where the aphid was active. Activity of the parasitoid in spring was severely reduced by chemical treatments. Because of the host specificity, distribution and synchronization with its host, P. antennata can be an effective biological control agent. Five species of hyperparasitoids, Dendrocerus carpenteri (Curtis) (Hym., Megaspilidae), Syrphophagus aphidivorus (Mayr) (Hym., Encyrtidae); Pachyneuron aphidis (Bouche), Euneura lachni (Ashmead) (Hym., Pteromalidae), and Tetrastichus sp. (Hym., Eulophidae) were active in the studied area. P. antennata was re-described and the differences from the original materials were discussed.
