Aphelinid versus encyrtid: first record of Marietta carnesi (Howard) (Hymenoptera: Aphelindae) in the Philipines and confirmation of its hyperparasitism on Comperilla calauanica Barrion, Almarinez and Amalin (Hymenoptera:Encyrtidae)

Abstract

Marrietta carnesi(Howard) is an alphelinid hyperparasite associated with other chalcidoid parasitoids of armored scale insects. Among its hosts are encyrtids of the genus Comperiella Howard, specifically C. bifasciata Howard and C. unifasciata Ishii. The authors' report not only a first record on this hyperparasite's occurrence in the Philippines, but also of its new parasitization records on C. calauanica Barrion,Almarinez and Amalin and its diaspidid host Aspidiotus rigidus Reyne. M. carnesi was first found among samples collected from a coconut palm in Sto. Tomas, Batangas in 2014, and later in Orani, Bataan in 2015. The occurrence of this hyperparasite could have implications on the mass rearing of C. calauanica for conservation and augmentation, but probably not so on the encyrtid's efficacy for biological control of A. rigidus.
