(Life: Kingdom: Metazoa (animals); Phylum: Arthropoda; Class: Hexapoda; Order: Hymenoptera; Superfamily: Platygastroidea; Family: Platygastridae; Subfamily: Sceliotrachelinae; Genus: Amitus)

Amitus hesperidum Silvestri, 1927. Holotype in Bologna, Italy. Type locality:
 

Distribution

Native to Asia, but has been introduced to many other parts of the world as a biocontrol agent.

Biology

Parasitoid of the citrus blackfly, Aleurocanthus woglumi (Hemiptera: Sternorrhyncha: Aleyrodidae) a major pest of citrus trees.

 

"In 1959, citrus blackfly was discovered near Durban, South Africa. Eradication was thought to be impractical because of the large number of dooryard citrus trees in the region, the hilly terrain, extensive plantings of mango (an alternate host), and the general lack of commercial and home treatment for scale pests of citrus. Shipments of Eretmocrus from Jamaica were subsequently established in South Africa, and the pest potential of citrus blackfly was reduced significantly (Bedford and Thomas 1965). Biological control using introduced parasites against the blackfly was also found to be effective in the Seychelles (Greathead 1971) and in Kenya. Within several years of the initial releases, sooty mold was virtually eliminated from citrus, and commercial control had been obtained without the use of insecticides (Wheatley 1964)." - verbatim quote from Hoelmer & Grace (1989).
