Chartocerus sp. (Hymenoptera: Signiphoridae) and Pachyneuron crassiculme (Hymenoptera: Pteromalidae) are Obligate Hyperparasitoids of Diaphorencyrtus aligarhensis (Hymenoptera: Encyrtidae) and Possibly Tamarixia radiata (Hymenoptera: Eulophidae)

Two species of suspected hyperparasitoids, Chartocerus sp. and Pachyneuron crassiculme, emerged from parasitized Diaphorina citri nymphs collected in Punjab Pakistan over 15-22 Apr 2013. Exposure tests conducted in quarantine on D. citri nymphs parasitized by Tamarixia radiata and Diaphorencyrtus aligarhensis, as well as unparasitized D. citri nymphs, confirmed that Chartocerus sp. and P. crassiculme are hyperparasitoids. Both Chartocerus sp. and P. crassiculme successfully reproduced on D. aligarhensis, with one instance of P. crassiculme reproducing on T. radiata. There was no emergence from unparasitized D. citri.
