Parasitoids on codling moth <i>Cydia pomonella</i> (Lepidoptera: Tortricidae) in apple and walnut orchards in Syria

Summary The codling moth [Cydia pomonella L. (Lepidoptera: Tortricidae)] is the main pest in most apple orchards in Syria. It causes billions of dollars in loss of fruit crops every year. The present work examined the effects of gamma radiation and Bacillus thuringiensis (BT) on F1 progeny of C. pomonella. The experimental design was based on two factors, namely F1 offspring produced by males irradiated at a dose of 150 Gy, and artificial diet of BT-treated larvae. The first offspring of unirradiated and irradiated C. pomonella males, F1, were from parents treated with a commercial formulation of Bacillus thuringiensis BT (Dipel® 2X). F1 progeny of unirradiated was significantly less susceptible to BT than that of irradiated parents. The results showed high mortality in F1 progeny of C. pomonella when gamma radiation and BT were applied together. The LC50 in F1 progeny was 2.5 ppm for irradiated parents, while it was 13 ppm for unirradiated ones. A significant reduction in the fecundity and egg hatchability of F1 progeny of irradiated parents compared to unirradiated ones was observed. This study demonstrated that for F1 progeny the combination between Inherited Sterility Technique and BT can be useful to achieve an integrated pest management program of codling moth.

Species of the family Pteromalidae from the Middle East countries are reviewed. A total of 445 species within 134 genera and 17 subfamilies are recorded from 20 countries including Algeria (25 genera, 37 species), Egypt (27 genera, 37 species), Iran (84 genera, 211 species), Iraq (13 genera, 18 species), Israel (34 genera, 53 species), Jordan (8 genera, 9 species), Kuwait (1 genus, 1 species), Lebanon (5 genera, 5 species), Libya (9 genera, 10 species), Morocco (71 genera, 122 species), Oman (3 genera, 5 species), Palestine (5 genera, 5 species), Saudi Arabia (10 genera, 14 species), Syria (11 genera, 15 species), Tunisia (15 genera, 17 species), Turkey (75 genera, 236 species), United Arab Emirates (7 genera, 7 species), Yemen (27 genera, 45 species). There are no published records from Pteromalidae from Bahrain and Qatar. On the basis of the new findings in this study, 22 species in 15 genera are collected and identified from various regions of Iran. Among them, the genera Blascoa Askew, 1997 and Plutothrix Förster, 1856 and three species, Blascoa ephedrae Askew, 1997, Plutothrix trifasciata (Thomson, 1878 and Homoporus pulchripes Erdös, 1953 are newly recorded for the fauna of Iran, the genus Blascoa Askew and three species are new for the Middle East fauna. Biogeographically, the species of Pteromalidae recorded from the Middle East are widely distributed in the Western Palaearctic region. Of which, 268 species were found only throughout the Palaearctic with no records from other regions. Among the countries of the Middle East, the highest percentage of endemism for Pteromalidae species were found in Turkey (56 species, 12.6%) and Yemen (25 species, 5.6%), later country representing the fauna of both Palaearctic and Afrotropical regions. The distribution in the Middle East and zoogeographical distribution For each species are presented.
