Sesamia nonagrioides (Lep.: Noctuidae) is one of the most serious pests of corn in Turkey and other Mediterranean countries. Although various cultural, chemical, and biological methods are used to control this pest, its damage still continues in all Mediterranean countries. | Turkish Journal of Biology Turk J Biol (2015) 39: 31-48 © TÜBİTAK doi: Research Article Identification and pathogenicity of bacteria in the Mediterranean corn borer Sesamia nonagrioides Lefebvre (Lepidoptera: Noctuidae) 1 1 2 3 1 1, Ardahan ESKİ , Filiz ÖZKAN ÇAKICI , Mustafa GÜLLÜ , Hacer MURATOĞLU , Zihni DEMİRBAĞ , İsmail DEMİR * 1 Department of Biology, Faculty of Sciences, Karadeniz Technical University, Trabzon, Turkey 2 Department of Entomology, Biological Control Research Station, Adana, Turkey 3 Department of Molecular Biology and Genetics, Faculty of Sciences, Karadeniz Technical University, Trabzon, Turkey Received: Accepted: Published Online: Printed: Abstract: Sesamia nonagrioides (Lep.: Noctuidae) is one of the most serious pests of corn in Turkey and other Mediterranean countries. Although various cultural, chemical, and biological methods are used to control this pest, its damage still continues in all Mediterranean countries. In this study, to find an effective bacterium that can be used as a biocontrol agent against S. nonagrioides, we isolated 15 bacteria from S. nonagrioides larvae and evaluated the larvicidal potency of all isolates on the pest. According to their morphological, physiological, biochemical, and molecular properties, the isolates were identified as Achromobacter insolitus (Sn1), Morganella morganii (Sn2), Klebsiella pneumoniae (Sn3), Citrobacter freundii (Sn4), Arthrobacter protophormiae (Sn5), Chryseobacterium indologenes (Sn6), Bacillus thuringiensis (Sn7), Bacillus safensis (Sn8), Bacillus thuringiensis (Sn9), Bacillus thuringiensis (Sn10), Klebsiella pneumoniae (Sn11), Staphylococcus sciuri (Sn12), Enterobacter kobei (Sn13), Serratia marcescens (Sn14), and Microbacterium arborescens (Sn15). The results of the larvicidal activities of these isolates indicated that the mortality value obtained from all treatments
