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
