none Entered purchase/A survey of the most abundant aphid species (Homoptera: Aphididae) and their associated parasitoids and predators found on 16 wild plants was conducted in the region of El-Arish, El-Sheikh Zewaid and Rafah in North Sinai, Egypt in two successive years 2011 and 2012. Fourteen aphid species were identified, 7 were recorded for the first time, Dysaphis foeniculus (Theobald), Aphis compositae Theoblad, Brachycaudus helichrysi (Kaltenbach), A. spiraecola Patch, Macrosiphum rosae (L.), Toxoptera odinae (Van der Goot) and Maculolachnus submacula (Walker). Also, Myzus persicae (Sulzer), A. fabae Scop., B. amygdalinus (Schouteden), A. gossypii Glover., Brevicoryne brassicae (L.), A. craccivora Koch and A. nerii Boyer. Associated parasitoid and predatory species were; 5 primary hymenopterous parasitoid species: Aphidius matricariae Haliday, Binodoxys anagelicae (Haliday), Ephedrus persicae Froggatt, Lysiphlebus confuses Tremblay et Eady, L. fabarum (Marshall), 2 hyperparasitoid species: Syrphophagus sp. and Alloxysta sp. and 6 predatory species: Coccinella undecimpunctata L., C. septempunctata L., Hippodama convergens Guerin-Meneville, Scymnus interruptus (Goeze), Chrysoperla cornea (Steph.) and Syrphus corollae Fabricius. Occurrence periods, locations, infested plant parts and abundance rates of the surveyed species were recorded. 2014
