    Morphological Changes Caused by Bacillus megaterium on Adult Emergence of Fall Webworm’s Pupa, Hyphantria cunea (Drury) (Lepidoptera: Erebidae)
    (Ankara Üniversitesi, 2018-12-05) Aksoy, Hasan Murat; Saruhan, İslam; Kaya, Yılmaz; Öztürk, Murat; Ziraat Fakültesi
    Insecticidal effects of Bacillus megaterium isolates maintained from bacterial oozed pupae were studied on pupae and 2nd instar larvae of Hyphantria cunea. The bacterial isolates were identified according to morphological, physiological, biochemical and sequence analyses. This study reported that Bacillus megaterium isolates, HMA5 and BM1, caused different abnormal wings shapes and hair loss on thorax and abdomen of Hyphantria cunea. In addition, the HMA5 and BM1 treated pupae showed significantly reduced ability of adult emergence rates. The percentages of the adult emergence from pupae were 1% and 2% for HMA5 and BM1, respectively.

    Samsun ilinde domates bakteriyel hastalıkları ve yaygınlıkları
    (Fen Bilimleri Enstitüsü, 2002) Aksoy, Hasan Murat; Maden, Salih
    Samsun İlindeki bakteriyel hastalık etmenleri ve yaygınlıkları 8 ilçede 1037.9 dekar alan gezilerek belirlenmiştir. Bakteriyel etmenler, fizyolojik özelliklerine, biyokimyasal ve patojenite testlerine göre teşhis edilmiştir. Samsun İli domates ekiliş alanlarında Clavibacter michiganensis subsp. michiganensis (% 0.64), Erwinia carotovora subsp. carotovora (% 0.22), Pseudomonas corrugata (% 0.53), Pseudomonas syringae pv. tomato (% 0.42) ve Xanthomonas vesicatoria (% 1.70) olmak üzere 5 adet bakteriyel hastalık etmeni tespit edilmiştir.Abstract Bacterial disease agents and their prevalence were determined by surveying 1037.9 dekar area in 8 towns of Samsun Province. Bacterial strains were identified according to their physiological, biochemical and pathogenicity tests. Five bacterial disease agents; Clavibacter michiganensis subsp. michiganensis (0.64 %), Erwinia carotovora subsp. carotovora (0.22 %), Pseudomonas corrugata (0.53 %), Pseudomonas syringae pv. tomato (0.42 %) ve Xanthomonas vesicatoria (1.70 %) were determined in tomato growing areas of Samsun.
