“…To date, P. aeroginosa has been isolated from, and been shown to be pathogenic to, several insect species (Banerjee & Dangar 1995;Inglis et al 2000;Osborn et al 2002). Banerjee & Dangar (1995) showed that P. aeroginosa is pathogenic to red palm weevil (Rhynchophorus ferrugineus (Olivier)) and caused 69% larval mortality. Inglis et al (2000) also observed that Pseudomonas spp.…”

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.

Eurygaster integriceps (Hemiptera: Scutelleridae) is one of the most serious pest of wheat and other cereal crops throughout the Near and Middle East including Turkey. To contribute biological control of this pest, we investigated the culturable bacterial flora of E. integriceps and their virulence against it. We also tested different entomopathogenic fungi (Isaria fumosorosea ARSEF8356, Beauveria bassiana ARSEF8356, Metarhizium brunneum ARSEF8671 and Nomurae rileyi ARSEF1670) against this pest under laboratory conditions. Bacterial isolates were characterized based on morphological, biochemical, physiological and molecular characteristics (16S rRNA sequencing). The isolates were identified as Pantoea sp. (S1, S5, S7, S8, S10 and S11), P. agglomerans (S2, S3 and S4), Pseudomonas sp. S6 and Micrococcus luteus S9. The highest mortality within bacterial isolates was observed from Pantoea sp. S1, P. agglomerans S4 and Pantoea sp. S7 with 100%. Mortality of other bacterial species ranged from 33% to 88%. The highest mortality among the tested entomopathogenic fungi was obtained from Isaria fumosorosea ARSEF 8333 with 100%. Mortality of other fungi ranged from 33% to 50%. Consequently, Pantoea sp. S1, P. agglomerans S4, Pantoea sp. S7, Beauveria bassiana ARSEF 8356 and Isaria fumosorosea ARSEF 8356 seem to be promising candidates in the control of E. integriceps.

“…The surface extract of other insects living in habitats full of pathogens exhibited antimicrobial activity (Butera et al 2009). Moreover, other authors have shown the action of some hydrocarbons detected in arthropods against entomopathogens (Banerjee & Dangar 1995). Recently, microbiological findings (Mazza et al 2011) showed that polar substances detected in the red palm weevil are effective against microorganisms.…”

Two native species of the genus Cucujus show a wide geographic distribution in Europe, Cucujus cinnaberinus (Scopoli, 1763) and C. haematodes Erichson, 1845. Although data on the distribution and ecology of these rare and endangered species are increasing, there are few reports on their biology and behaviour, and some aspects of their feeding ecology remain problematic. Our aim was to study, for the first time, the cuticular chemical profiles of these two beetles to (i) investigate the presence of chemicals potentially involved in defence by pathogens and (ii) lay the foundation for understanding the role of their bright red colour. The analysis of the cuticular profile was performed in-vivo by solid phase microextraction coupled with gas chromatography-mass spectrometry. In the cuticular profiles of the two species we identified 24 compounds belonging to different classes of molecules, i.e. hydrocarbons, aldehydes, esters, n-alkyl morpholines, and a high number of organic acids. Qualitative differences in terms of both signal intensity and detected compounds were found between the two species. As reported in other insects, the remarkable array of avoidance substances suggests a strict relationship with the bright red colour of the adults, which probably acts as an aposematic or warning signal. European Cucujus species are probably well protected against enemies because some identified chemicals, particularly fatty acids, are related to an antipredatory strategy to fight off predators that use their sense of smell to locate their prey. Other substances found on the cuticular layer of these beetles are probably involved in an antimicrobial and antifungal function, as demonstrated in other insects living in habitats that host many pathogens.
