AbstractIsolation, 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. The bacterial microbiota of O. nubilalis were identified as Pseudomonas aeruginosa (On1), Brevundimonas aurantiaca (On2), Chryseobacterium formosense (On3), Acinetobacter sp. (On4), Microbacterium thalassium (On5), Bacillus megaterium (On6), Serratia sp. (On7), Ochrobactrum sp. (On8), Variovorax paradoxus (On9), Corynebacterium glutamicum (On10), Paenibacillus sp. (On11), Alcaligenes faecalis (On12), Microbacterium testaceum (On13), Leucobacter sp. (On14), Leucobacter sp. (On15) and Serratia marcescens (On16) based on their morphological and biochemical characteristics. A partial sequence of the 16S rRNA gene was also determined to confirm strain identification. The highest insecticidal activities were obtained from P. aeruginosa On1 (80%), Serratia sp. On7 (60%), V. paradoxus On9 (50%) and S. marcescens On16 (50%) against larvae 14 days after treatment (p < 0.05). Also, the highest activity from previously isolated Bacillus species was observed from Bacillus thuringiensis subsp. tenebrionis Xd3 with 80% mortality within the same period (p < 0.05). Our results indicate that P. aeruginosa On1, Serratia sp. On7, V. paradoxus On9, S. marcescens On16 and B. thuringiensis subsp. tenebrionis Xd3 show potential for biocontrol of O. nubilalis.

“…S. marcescens is not usually pathogenic to insects when present in the digestive tract in small numbers, but once it enters the hemocoel, it multiplies rapidly and causes death in 1-3 days (Sikorowski et al, 2001). Studies have shown the pathogenic properties of this bacterium against many insect pest species (Lauzon et al, 2003;Gokce et al, 2010).…”

IntroductionChitin, a linear polymer of β-1,4-linked N-acetyl-Dglucosamine (GlcNAc), is one of the most abundant biopolymers in nature. It is the main component of the exoskeleton of many invertebrates such as crustaceans, insects, and spiders and a structural component of the cell walls of most fungi and algae. In insects it functions as scaffold material, supporting the cuticles of the epidermis and trachea as well as the peritrophic membrane (PM) lining the gut epithelium (Merzendorfer and Zimoch, 2003;Ruiz-Sanchez et al., 2005;Kuzu, 2008).Chitinases are glycosyl hydrolases that catalyze the hydrolytic degradation of chitin. Chitin, which is found in the structure of cuticles and peritrophic membranes, is degraded by the chitinase enzymes. The degradation decreases the feeding and defenses of the insect and weakens it. Therefore, chitinases are important enzymes that have potential for being used as biological control agents against harmful insects (Cohen, 1987;Debaditya et al., 2007;Kuzu, 2008). Chitinases have been detected in a great variety of organisms, including those that contain chitin, such as insects, crustaceans, yeasts, and fungi, and also organisms that do not contain chitin, such as bacteria, higher plants, and vertebrates. Several genera of bacteria, including Serratia (

IntroductionCorn is the largest grown cereal crop in the world with doubled grain yield per unit area compared to wheat and barley. Although corn production holds second place in Mediterranean agricultural production, there has been a sharp decline in this value due to infestation by the Mediterranean corn borer (Özcan, 2009). The Mediterranean corn borer, Sesamia nonagrioides (Lefebvre) (Lepidoptera: Noctuidae), is a major multivoltine pest of maize in Mediterranean countries (Tsitsipis, 1988;Alexandri and Tsitsipis, 1990). S. nonagrioides is a polyphagous species with a fairly wide range of host plants, including corn, sorghum, millet, rice, sugar cane, grasses, melon, asparagus, palms, and banana (Uygun and Kayapınar, 1993;Sannino et al., 2004). The population levels of this species, which has considerable potential to establish itself in an area and become abundant, may therefore depend on the abundance of these hosts (Eizaguirre and Fantinou, 2012). If insecticides are not applied, losses could rise to 100% in late and second crop production (Alexandri and Tsitsipis, 1990).Application of chemical insecticides against this harmful insect is recommended 2-3 times per growing season. However, yield losses could rise to 30% during seasons with severe insect outbreaks, even after 4-5 insecticide applications (Özcan, 2009). As well as causing significant maize crop losses, the insects reduce the nitrogen/protein content of grain by tunneling into the stem and cobs, where they are likely to interfere with the uptake of plant nutrients (Bayram, 2003). Furthermore, mycotoxigenic fungi associated with the pest often invade wound sites and can greatly depreciate the crop value (Avantaggiato et al., 2003). Although several control methods have been previously applied to this pest, damage is still pervasive. Chemical insecticides have been frequently used against it. While chemicals decrease pest population, they cause major threats to the environment and human health. Mechanical, cultural, and biological 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 marce...
