| Abstract | ||||
| The hemispherical scale, Saissetia coffeae (Walker) (Hemiptera: Coccidae) has been recorded on olive, coffee, guava ornamental plants especially of cycads and frens and numerous other hosts in many subtropical and tropical areas. A survey of predators of S. coffeae specially their abundance was carried out during 2004-2005 on different host plants in four localities, namely, Gharbiya Giza Marsy Matrouh and North Sinai (EI-Arish) . Twelve species of predators of S. coffeae were collected. The coleopterous predators were Coccinella septempunctata L., C. undecimpunctata L., Scymnus interruptus Goez. Scymnus syriacus Mars. ,Exochomus flavipes Rodalia cardinals Muls. and Paederus alfierii Koch. The neuropterous predator was Chrysoperlla carnae Steph . The hemipterous predator were Orius laevigatus Fieb., Orius albidipennis (Reuter). The dipterous predator were Metasyrphus corollae Fab. and Paragus compeaitus Wied. On the other hand S. syriacus was the most abundant predator attacking S. coffeae in all locations under investigations | ||||
