| Abstract | ||
| Aphelinids (Hymenoptera : Aphelinidae) are the most important parasitoids of, armored scale, soft scale insects ( Hemiptera: Coccoidea ) and whiteflies ( Hemiptera: Alyerodoidea). The present work dealt with the diagnosis and abundance and the role of this group in controlling armored scale, soft scale insects and whiteflies. The results indicated that 17 parasitoids and hyperparasitiods were reared from samples of armored , soft scale insects and whiteflies in different locations in Egypt. These parasitoid and hyperparasitiod species were collected from 7 armored, soft scale insects and whiteflies and distributed in 5 Governorates (Alexandria, Assuit, Ismailia, Fayoum and Matruh). The maximum rate of parasitism of armored scale insects parasitoids ranged between 12-59% during the two years under consideration. While the maximum rate of parasitism of soft scale insects and whiteflies parasitoids ranged between 13-28% and 39-58%,. during the two years under consideration, respectively. This result indicated that some parasitoids of armored, soft scale insects and whiteflies were effective in controlling them | ||
