Seven closely related xylanolytic, thermophilic bacilli were isolated from mud and water samples from the Gonen and Diyadin hot springs, respectively located in the Turkish provinces of Balikesir and Agri. On the basis of morphology and biochemical characteristics, one of the isolates, designated strain G2(T), was studied further. Strain G2(T) is a(More)
Isolation, characterization and virulence of the culturable bacteria from entire tissues of larval Ostrinia nubilalis (Hübner) (Lepidoptera: Pyralidae) were studied to obtain new microbes for biological control. A total of 16 bacteria were isolated from living and dead larvae collected from different maize fields in the Eastern Black Sea Region of Turkey.(More)
The chitinase B (chiB) and C (chiC) genes and flanking regions from a local isolate of Serratia marcescens were cloned individually and sequenced. Results showed that these chiB and chiC genes have a 96 % maximum similarity with chiB and chiC from different S. marcescens species (GenBank numbers Z36295.1 and AJ630582.1, respectively). The amplified chiB(More)
Hydrophobins are small, cysteine-rich, secreted proteins, ubiquitously produced by filamentous fungi that are speculated to function in fungal growth, cell surface properties, and development, although this has been rigorously tested for only a few species. Herein, we report identification of three hydrophobin genes from the entomopathogenic fungus,(More)
Peritrophic membrane (PM) is present in most insects’ midgut and acts as a mechanical barrier to protect the epithelium from various harmful factors such as pathogens or toxins. Chitinase is a virulence factor due to its ability to degrade the chitin content of PM. Therefore, chitinase is a mediator for easier binding of toxins to gut epithelium and(More)
Thaumetopoea pityocampa (pine processionary moth) is one of the most important pine pests in the forests of Mediterranean countries, Central Europe, the Middle East and North Africa. Apart from causing significant damage to pinewoods, T. pityocampa occurrence is also an issue for public and animal health, as it is responsible for dermatological reactions in(More)
Chilo iridescent virus (CIV) is the type member of the genus Iridovirus within the family Iridoviridae. The virions of CIV contain a single linear dsDNA molecule that is circularly permuted and terminally redundant. The genome of CIV contains an open reading frame (ORF 012L) encoding a protein homologous to exonuclease II of Schizosaccharomyces pombe. In(More)
Mole crickets are significant pests of turf, vegetable and some tree seedlings worldwide, and it is costly to control them. In this study, we obtained 15 fungal isolates from Gryllotalpa gryllotalpa L. (Orthoptera: Gryllotalpidae) and compared the efficacy of these isolates against this pest with the aim of identifying their biocontrol potential. The fungal(More)
The open reading frame (ORF) amv133 of Amsacta moorei entomopoxvirus, encodes a putative lipase gene. Its temporal expression pattern was characterized by RT-PCR and found to start at 6 h postinfection (h p.i.) and reach a maximum level at 48 h p.i. While the ORF has a late promoter motif, the inhibition of viral DNA synthesis by Ara-C failed to inhibit(More)
The present study was conducted to identify the microbial flora of pest weevils Sciaphobus squalidus (Gyll.), Tatianaerhynchites aequatus (L.) and Byctiscus betulae L., which may provide novel approaches for insect biocontrol. According to morphological, physiological, biochemical and molecular properties thirteen bacteria were revealed and characterized.(More)
