Abstract<\/strong><\/p>\n

Psyttalia concolor<\/em> Szpli (Hym: Braconidae) is considered a larva-pupa parasitoids, on Bactrocera oleae<\/em> (Diptera: Tephritidae) the main pest on olive fruit in the world. This is due to the importance of Psyttalia concolor<\/em> within the complex parasitoids of olive fruit fly, and coexistence of this parasitoid in Syria.
\nThe aim of this research was ecological and biological study of the parasitoid Psyttalia (Opius) concolor<\/em> Szpli (Hym: Braconidae) on olive orchards of Lattakia and Idleb. This study was carried out in 2006 & 2007.
\nDynamic of olive fruit fly studied and the number of generation, olive fruit fly recorded five generation in Lattakia province (Ein Alwan, Baksa and Samea) and four generations in Aljanodea in Idleb in 2006&2007. However four generation in Ansas in Idleb in 2006 and three generations in this place in 2007 were recorded.
\nWhen exploration the parasitoids associated to B. oleae, we recorded seven parasitoids associated with olive fruit fly in all locations within 2006& 2007 belong to Hymenoptera & Diptera, six of them belong to order Hymenoptera, five belong to super family Calcidodea<\/span>, and they are ectoparasites on the immature stage (larva-pupa) of olive fruit fly Eupelmus urozonus<\/em> Dalm, Eurytoma martellii<\/em> Dom, Pnigalio argaules<\/em> Fer.&Del, Chlorocystus<\/em> sp., Callocleonymus<\/em> sp, and one parasitoid belongs to super family Ichneumonidea Psyttalia (Opius) concolor<\/em> Szpl, this parasitoids is endoparasite (larva-pupa), and parasitoid belong to order Diptera, this is Prolasioptera berlesiana<\/em> Paoli, this parasitoid feeding on eggs and larvae.
\nHowever, the activity of P. concolor<\/em> on olive fruit fly B. oleae<\/em> was evaluated.
\nThe percentage of the parasitoid Psyttalia concolor<\/em> adults recorded 3- 4 peaks in Lattakia (Ein Alwan, Baksa and Samea ) in 2006& 2007, which were associated with the 2nh, 3rd, 4th, 5th generation of B .oleae<\/em> as recorded in these three locations in 2006 & 2007. However, in Idleb 1-3 peaks in (Aljanodea, Insas) associated with the 2nh, 3rd, 4th, generation of B .oleae as recorded in these two locations in 2006 & 2007.
\nPercent P. concolor<\/em> to other parasitoids on B. oleae<\/em> at the end of October in 2006 was: 19, 23, 18.5, 20.2 and 17.4% in Ein Alwan, Baksa, Samea, Aljanodea and Insas respectively.
\nHowever, in 2007 they were 21, 15, 11.5, 16.6, and 3.7% respectively in these places and in the same time.
\nWhen studying the diapauses of Psyttalia concolor<\/em>, where\u00a0 a large sample of 3rd larva of Bactrocera oleae<\/em> collected from Lattakia province (Ein Alwan, Baksa and Samea) and Idleb province (Insas and Aljanodea) during the end of harvesting seasons\u00a0 (November) 2006& 2007 to study the diapause of Psyttalia (Opius) concolor<\/em> Szpl (Hym: Braconidae). All larvae of B. oleae were pupa in 4-7cm in soil, so we cant record real dormancy to pest add its parasitoid. Most adults of B. oleae<\/em> & P. concolor<\/em> emerged from soil under natural laboratory conditions in December & January during study seasons. The parasitoid was absent between middle March and end June, however, B. oleae<\/em> was recorded on color traps in olive fields at the same time in Lattakia and Idleb during both study seasons.<\/p>\n","protected":false},"excerpt":{"rendered":"
