We studied the parasitic complex of the African citrus
psylla, Trioza erytreae for the first time in the
tropical zone of Africa, in Cameroon. This psyllid is
the major pest of citrus in all high and humid land regions
in Cameroon and is parasitized by numerous hymenopterans.
Under natural conditions, we discovered that 17 different
species of Hymenoptera laid their eggs on nymphs of T.
erytreae. These parasitoids belong to the families
Aphelinidae, Ceraphronidae, Encyrtidae, Eulophidae, and
Figitidae. We provide an identification key for adults who
can permit recognition and identification of all parasitoids
of T. erytreae. New species are cited for the first
time in this complex of parasitoids of this psyllid.
Key words: Citrus, Trioza erytreae,
hymenoptera, parasitoids, pest control, Cameroon. |
