Aprostocetus ceroplastae

Aprostocetus ceroplastae (Girault)

(Formerly placed in the genus Tetrastichus)

Taxonomic placing: Insecta, Holometabola, Hymenoptera, Apocryta, Chalcidoidea, Eulophidae.

Geographical distribution: Holarctic, Near East and introduced into parts of Africa and Australia for biocontrol purposes.

Morphology: The female is shiny, metallic-black, about 1.0-1.5 mm in length, legs mostly yellow, wings hyaline, antenna yellow, with long setae.

Life history: Aprostocetus ceroplastae is an endoparasitoid of the third instar and young females of soft scales. Its threshold of development is at 7°C, and 460 day degrees are required to complete a generation. The eggs placed In the bodies of some of its hosts become encapsulated, inhibiting their development; the rates of encapsulation are affected by the scale’s host plant.

Economic importance: Aprostocetus ceroplastae is an important, common enemy of Middle Eastern pestiferous Coccidae, like Ceroplastes floridensis and of Ceroplastes rusci.

Effect of pesticides: An insect growth regulator (IGR), organophosphates and a carbamate, when applied against coccids, were very toxic to A, ceroplastae.
