“…A number of Pseudomonas species are important insect pathogens, i.e., P. chlororaphis (Bucher 1981), P. fluorescens (Sezen & Demirbag 1999) and P. aeruginosa (Osborn et al 2002). Despite P. putida isolate appears insignificant as an insect pathogen (Schneider & Dorn 2001), our P. putida isolate (Ld4) is highly pathogenic against L. decemlineata larvae (Muratoglu, Demirbag & Sezen, unpublished results).…”

Colorado potato beetle, Leptinotarsa decemlineata (Say), is a devastating pest of potatoes in North America and Europe. L. decemlineata has developed resistance to insecticides used for its control. In this study, in order to find a more effective potential biological control agent against L. decemlineata, we investigated its microbiota and tested their insecticidal effects. According to morphological, physiological and biochemical tests as well as 16S rDNA sequences, microbiota was identified as Leclercia adecarboxylata (Ld1), Acinetobacter sp. (Ld2), Acinetobacter sp. (Ld3), Pseudomonas putida (Ld4), Acinetobacter sp. (Ld5) and Acinetobacter haemolyticus (Ld6). The insecticidal activities of isolates at 1.8×109 bacteria/mL dose within five days were 100%, 100%, 35%, 100%, 47% and 100%, respectively, against the L. decemlineata larvae. The results indicate that Leclercia adecarboxylata (Ld1) and Pseudomonas putida (Ld4) isolates may be valuable potential biological control agents for biological control of L. decemlineata.

“…Oncocin is a chemically optimised analogue of the 2 kDa Oncopeltus antibacterial peptide 4, which was originally isolated from Oncopeltus fasciatus [15]. Its high A c c e p t e d M a n u s c r i p t -10 -antibacterial activity against several Gram-negative human pathogens makes it a promising lead compound for systemic administration.…”

“…In previous studies, it was reported that P. putida could infect Euproctis chrysorrhoea (Steinhaus, 1963) and Mamestra brassicae (Lepidoptera: Noctuidae) (Ivanov & Gukasjan, 1966). Despite the fact that a number of Pseudomonas species are important insect pathogens, i.e., P. aeruginosa (Bucher & Stephens, 1957;Osborn et al, 2002), P. fluorescens (Krieg, 1961;Lipa & Wiland, 1972;Bucher, 1981;Sezen & Demirbag, 1999, Yaman et al, 1999 and P. chlororaphis (Ivanov & Gukasjan, 1966;Bucher, 1981;Yaman et al, 2002b), P. putida appears insignificant as an insect pathogen (Bucher, 1981;Schneider & Dorn, 2001).…”

Abstract:The European spruce bark beetle, Dendroctonus micans Kugelann (Coleoptera, Scolytidae), is one of the most serious pests of oriental spruce (Picea orientalis L.) in Turkey. In this study, we investigated bacterial flora of D. micans collected from different populations of the forests of Eastern Black Sea Region of Turkey from 2002 to 2004. Seven different bacteria were isolated from healthy, diseased and dead specimens based on the color of colony and morphology. According to morphological, physiological and biochemical properties, metobolic enyzme profile by BIOLOG microtiter plate system, and total cellular fatty acid profile by Microbial Identification System (MIS), isolates were identified as Micrococcus luteus, Bacillus thuringiensis subsp. morrisoni, Serratia grimesii, Enterobacter cloaceae, Enterobacter intermedius, Streptococcus sp. and Pseudomonas putida. This is the first study on the bacterial flora of D. micans.
