First report of Juglans australis (Juglandaceae) as a natural host plant for Anastrepha schultzi (Diptera: Tephritidae) with notes on probable parasitism by Doryctobracon areolatus, D. brasiliensis, Opius bellus (Braconidae) and Aganaspis pelleranoi (Figitidae)

Abstract

We document for the first time that J. australis is a natural host plant of Anastrepha schultzi Blanchard, a species belonging to the fraterculus group. We also confirm earlier reports indicating that A. schultzi infests P. guajava. Fruit were collected in the locality of Horco Molle, province of Tucumán in NW Argentina, in a perturbed “Yungas” forest (Montane Cloud Forest). Infestation rates were 318.5 and 492.6 larvae per kg of fruit in J. australis and P. guajava, respectively. We also report that A. schultzi and A. fraterculus are attacked by the larval-pupal hymenopterous parasitoids Aganaspis pelleranoi (Figitidae), Doryctobracon areolatus, D. brasiliensis and Opius bellus (all Braconidae) in the study region.
