    Species composition of parasitoids of the tobacco aphid, Myzus nicotianae Blackman (Homoptera: Aphididae) in Eastern Tennessee

    SONG J.; PLESS C.D.; MILLER R.D.
    University of Florida, Dept. of Entomology and Nematology, Gainesville, FL, USA.
    The tobacco aphid, Myzus nicotianae Blackman, was commonly parasitized on tobacco plants, Nicotiana tabacum L., in greenhouses but rarely in the field. Five species of primary hymenopteran parasitoids were collected from greenhouses; only one primary ...
