Luck, R.F., Podoler, H., & Kfir, R. 1982 Host selection and egg allocation behaviour by Aphytis melinus and A. lingnanensis: comparison of two facultatively gregarious parasitoids.. Ecological Entomology 7: 397-408.

Notes: These ectoparasitic wasps were introduced into California as biological control agents of California red scale, Aonidiella aurantii. A. melinus utilizes smaller hosts than A. lingnanensis to produce progeny, therefore these parasitoids should not be considered ecological homologues.
