New Species and Strains of Aphytis (Hymenoptera, Eulophidae) Parasitic on the California Red Scale, Aonidiella Aurantii (Mask.), in the Orient1

Abstract

This paper deals primarily with the Aphytis species or to five species (or forms) of Oriental Aphytis parasitic on lesser categories considered to be definite and regular the California red scale. Two new species, Aphytis parasites of the California red scale, Aonidiella aurantii melinus and A. fisheri, are described, as are two forms (Mask.), in the Orient. The importance of species of whose status is in doubt, the Assam form of A. hispanicus Aphytis as parasites of diaspine scale insects is discussed and the Kagoshima form of A. citrinus. The adult and the potential value of strains or other subspecific females of A. melinus and A. fisheri are very similar, if categories in biological control is emphasized. Pupal not indistinguishable, morphologically, but they do not ipigmentation is described for four species or groups and interbreed and the pupae are quite distinct. The known s shown to be of taxonomic importance. A key is given distribution of these species in the Orient is given.
