“…The Bacillus species commonly recognized as definitive insect pathogens, however, are B. popilliae (formerly B. popillae), B. lentimorbus, B. larvae, B. thuringiensis, and certain strains of B. sphaericus (Stahly et al 1992). The spore-forming bacilli are viewed as having the highest potential for use in the management of insect pest populations, and these organisms have received the greatest commercial attention.…”

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.

“…This genus is the most studied group of bacteria in insect pathology (Boemare and Tailliez 2010) and is commonly recognized as definitive insect pathogens (Stahly et al 2006;Masetti et al 2008). Among Bacillus species, Bacillus subtilis (CQ3) and Bacillus tequilensis (CQ4) have been isolated from many insect species belonging to a variety of different orders at various times (Omoya and Akinyosoye 2011;Sevim et al 2012a).…”

Cimbex quadrimaculatus (Hymenoptera: Cimbicidae) is one of the serious pests of almonds in Turkey and worldwide. Since there is no effective control application against this pest, it has been a serious problem up to now. Therefore, we aimed to find an effective bacterium that can be utilized as a biocontrol agent against C. quadrimaculatus in pest management. We isolated seven bacteria from dead and live C. quadrimaculatus larvae, and evaluated the larvicidal potency of all isolates on the respective pest. Based on the morphological, physiological, biochemical and molecular properties (partial sequence of 16S rRNA gene), the isolates were identified to be Bacillus safensis (CQ1), Bacillus subtilis (CQ2), Bacillus tequilensis (CQ3), Enterobacter sp. (CQ4), Kurthia gibsonii (CQ5), Staphylococcus sp. (CQ6) and Staphylococcus sciuri (CQ7). The results of the larvicidal activities of these isolates indicated that the mortality value obtained from all treatments changed from 58 to 100 %, and reached 100 % with B. safensis (CQ1) and B. subtilis (CQ2) on the 3rd instar larvae within 10 days of application of 1.89 × 10(9) cfu/mL bacterial concentration at 25 °C under laboratory conditions. Findings from this study indicate that these isolates appear to be a promising biocontrol agent for C. quadrimaculatus.

“…Within this genus, there are many bacterial species which are related to insects. The best-known examples are B. thuringiensis, B. popilliae and, B. sphaericus (Stahly et al 2006). In this study, we isolated eight Bacillus strains (six of them were B. pumilus from C. maculatus and two of them were Bacillus sp.…”

Symbiotic bacteria associated with insects play important roles in different physiological processes such as digestion, insect behavior, defense and providing essential nutrition in insect gut. In addition, these bacteria can be used in biocontrol of insect pests using genetic engineering techniques. The first step is to isolate and identify symbiotic bacteria from insects to elucidate their roles, and to use in the development of transgenic strains. For this purpose, we isolated and characterized the bacterial isolates from stored product pests using a combination of conventional tests and 16S rRNA sequence analysis. The bacterial flora of Callosobruchus maculatus included Bacillus pumilus, Staphylococcus sp. and Pantoea sp. Acanthoscelides obtectus flora included Staphylococcus kloosii, Staphylococcus sp., S. saprophyticus and Enterococcus faecalis. The internal flora of Sitotroga cerealella included Staphylococcus succinus, Enterococcus sp. and Staphylococcus sp. Finally, Phthorimaea operculella flora included Bacillus sp., S t a p h y l o c o c c u s s c i u r i , E n t e ro c o c c u s m u n d t i i , E. casseliflavus, Alcaligenes faecalis, Enterobacter sp., Pantoea agglomerans and Pseudomonas fluorescens.
