| Abstract |
The soft brown scale, Coccus hesperidum L. (Homoptera: Coccidae) is an important pest of orchards trees in Egypt. During January, 2003 - December, 2004 survey of C. hesperidum parasitoids and predators was conducted. The following thirteen parasitoid species of aphelinids, encyrtids, eulophids, mymarids and pteromalids were collected and recorded. Parasitoids included: Alaptus sp., Coccophagus bivittatus Compere, C. ishii Compere, C. lycimnia (Walker), C. scutellaris (Dalman), Diversinervus e%gans Silvestri, Encarsia citrina (Craw), Marietta leopardina Motschulsky, M. picta (Andre), Microterys flavus (Howard), Parechthrodryinus coccidiphagus (Mercet), Scutellista cyanea Motschulsky and Tetrastichus sp. Six of them are new records in Egypt. However, 8 predators were collected, these are Chrysoperla carnea (Stephens), Chrysopa septempunctata Wesm., Coccinella septempunctata L., Orius laevigatus Fieb., Orius albidipennis Reuter, Scymnus interruptus Goez., Exochomus flavipes Thunb. and Metasyrphus corollae Fab. Abundance of these parasitoid and predator species was evaluated in three locations, namely Gharbiya, Qalyubiya and Giza. C. scutellaris and E. flavipes were collected from all investigated locations and were the effective natural enemies of C. hesperidum.
