Namık Kemal University, Faculty of Agriculture, Department of PlantProtection. Tekirdag-Turkey) Abstract: Bacterial spot disease caused by Xanthomonas axonopodis pv.vesicatoria (X. axonopodis pv. vesicatoria) is a devastating pepper (Capsicum annuum) disease in Turkey.Biological control of Xanthomonas axanopodis pv. vesicatoria is of great interest, in terms of environmentalsafety and economic return. In this study, 3 Bacillus strains isolated from soil samples of the rhizospheres ofpeppers grown in greenhouses and fields were used to suppress the size of the population of X axonopodispv. vesicatoria. Results indicated that disease development decreased by 11%-62% and 38%-67% in pepperplants inoculated with the 3 Bacillus strains alone and in combination, respectively. in greenhouse and fieldexperiments. In addition, stem diameter, root elongation, root dry weight, shoot dry weight. and yield increasedin response to the treatments in the field experiment by 7.0%-20.5%, 7.0%-17.0%, 4.5%-23.5%. 16.5%-38.5%. and by 11.0%-33.0%. respectively. This is the first study to report the successful biological control ofbacterial spot disease caused by X. axonopodis pv. vesicatoria using Bacillus species in TurkeyOzder, N., Effect of cold storage of adult Trichogramma brassicae, T. cacoeciaeand T. evanescens (Hym.: Trichogrammatidae). Archives of Phytopathologyand Plant Protection 41 (4): 296-299. (Prof.Dr. N.Ozder. Namık Kemal University, Faculty ofAgriculture, Department of Plant Protection. Tekirdag-Turkey)Abstract: Trichogramma cacoeciae Marchall, T.brassicae Bezdenko and T. evanescens Westwood could be useful in biological control programmes ofagricultural insect pest. The possibility of storing adult Trighogramma species at low temperatures, and theeffect of such storage on the quality of the parasitoids and its fecundity were studied. Trighogrammacacoeciae, T. brassicae and T. evanescens adults were stored for 1, 2, 3, 4 and 5 days at 41C in arefrigerator, 60-70%RH and full darkness. Storage at 41C reduced fecundity and longevity of femaleparasitoids.Ozder, N and Saglam, O. 2008.

(Prof.Dr. N.Ozder,Research Asist. O.Saglam. Namık Kemal University, Faculty of Agriculture, Department of Plant Protection.Tekirdag-Turkey) Abstract: The development time, survivourship and reproduction of Tuberolachnus salignus(Lachninae: Lachnini) were studied on Salix alba at five constant temperatures (17.5, 20, 22.5, 25 and 27.5C).The developmental time of immature stages ranged from 17.00 days at 17.5C to 12.21 days at 25C on S.alba. The total percentage of survivourship of immature stages varied from 50 to 70% at 17.5 to 20C on S.alba. The largest r m value occurred with 0.2540 at 20C on S. alba. The mean generation time of the populationranged from 13.595 days at 22.5C to 19.60 days at 17.5C on S. alba. The optimum temperature for T.salignus was 20C.Bilimsel Tam Metni Basılmış Uluslar arası BildirilerSunulu BildirilerĐlbağı, H., Çıtır, A. and Bostan, H. 2008. “Prunus spinosa L. a natural wild hostof some important fruit viruses in Tekirdağ.

Prof.Dr. Đlbağı, H. and Prof.Dr. A. Citir. Namık Kemal University, Faculty of Agriculture,Department of Plant Protection, Tekirdağ-Turkey.) Abstract: Blackthorn Prunus spinosa L. is a wide spreadbush along the road sides, water canals, field borders and hedgerows throughout the Trakya region of Turkey,especially in the Tekirdag province. Fifty four symptom expressing bushes were tested serologically withDouble antibody sandwich enzyme linked immunosorbent assay (DAS-ELISA) tests by employing antiseraagainst Plum pox virus (PPV), Apple chlorotic leaf spot virus (ACLSV) and Apple mosaic virus (ApMV). DAS-ELISA test results revealed that 13 out of 54 samples were found infected by PPV with a rate of 24.1%, 8 outof 54 samples contained ACLSV with a rate of 11.1% and 12 out of 54 of them had ApMV with a rate of22.2%. One of the PPV infected samples was also subjected to reverse transcription-polymerase chainreaction (RT-PCR) molecular test by isolating RNA from PPV infected leaves. By amplifying specific primers ofPPV-M strain, a band was detected 198 bp fragment. The result of DAS-ELISA and RT-PCR test revealed the34
