Eretmocerus siphonini Viggiani and Battaglia is one of parasitoids that showed a promising trend towards control of some whitefly species. The classical biological control of Siphoninus phillyreae (Haliday) (Homop­te­ra: Aleyrodidae) and Aleurolobus niloticus Priesner and Hosny (Homop­te­ra: Aleyrodidae) was achieved through mass rearing and releasing of E. siphonini in three governorates in Egypt during 1998-1999. A total of 237,020 parasitoids were reared and released in Assiut, Giza and Sharqiya governorates. The rate of parasitism increased from 5 to 60% and from 21 to 65% during 1999-2000, respectively, in Assiut. In Giza governorate, the increase amounted 2 to 46 and 10 to 67% on S. phillyreae on pome­gra­nate plant. Accordingly, E. siphonini showed that, it is an effective parasitoid legible for control of this whitefly. Similarly, the parasitism rates of E. siphonini increased (from 8 to 67% and 12 to 73 in Assiut and from 14 to 76 and 27 to 70% in Sharqiya) after releasing of the parasitoids on A. niloticus on ziziphus plants which showed the important role of this parasitoid in Egypt.
