“…B. popilliae recently isolated from Papuana spp. (Theunis and Aloali'i, 1998b;Theunis et al, 1997) could possibly be used as stressor to increase susceptibility of Papuana to entomo- and adult P. uninodis in pot assays exposed to S. glaseri #326: percentage mortality (average of corrected mortality) after 2 weeks in larvae and after 2 and 3 weeks in adults. The LD50 in larvae after 2 weeks was 1.4´10 6 (1.1 ± 1.6´10 6 ) nematodes/m 2 , in adults after 2 and 3 weeks 4.7´10 6 (4.1 ± 5.3´10 6 ) and 2.5´10 6 (2.2 ± 2.7´10 6 ) respectively.…”

“…Currently, studies on non-Bt bacteria have mainly focused on Paenibacillaceae, Morganellaceae, Yersiniaceae and Pseudomonadaceae. Paenibacillus popilliae (Bacillales Paenibacillaceae) were reported as pathogens of Popillia japonica (Coleopteran Scarabaeidae) and Papuana uninodis (Coleopteran Scarabaeidae) [ 14 , 15 ]. Another Paenibacillaceae bacterium, Brevibacillus laterosporus (Bacillales Paenibacillaceae), was discovered to be toxic to Plutella xylostella (Lepidoptera Plutellidae) and to produce chitinases [ 16 ].…”

The discovery and isolation of new non-Bt insecticidal bacteria and genes are significant for the development of new biopesticides against coleopteran pests. In this study, we evaluated the insecticidal activity of non-Bt insecticidal bacteria, PPBiotE33, IPPBiotC41, IPPBiotA42 and IPPBiotC43, isolated from the peanut rhizosphere. All these strains showed insecticidal activity against first- and third-instar larvae of Holotrichia parallela, Holotrichia oblita, Anomala corpulenta and Potosia brevitarsis. IPPBiotE33 showed the highest toxicity among the four strains and exhibited virulence against Colaphellus bowringi. The genome of IPPBiotE33 was sequenced, and a new protein, 03673, with growth inhibition effects on C. bowringi was obtained. In addition, IPPBiotE33 had a synergistic effect with Bacillus thuringiensis Bt185 against H. parallela in bioassays and back-inoculation experiments with peanut seedlings. IPPBiotE33 induced a decrease in hemocytes and an increase in phenol oxidase activity in H. parallela hemolymph, known as the immunosuppressive effect, which mediated synergistic activity with Bt185. This study increased our knowledge of the new insecticidal strain IPPBiotE33 and shed new light on the research on new insecticidal coaction mechanisms and new blended pesticides.

“…When orally ingested by insects, the crystal δ-endotoxins proteins of Bt formed, which are highly toxic to insects (Candas et al, 2003;Balaraman, 2005;Roh et al, 2007).The Bt preparations are the most successful bio-control products worldwide (Kaur, 2002). Bt has been used to control lepidopteran, coleopteran and dipteran pests on food crops, ornamentals, forest trees and stored grains (Iriarte et al, 1998;Theunis and Aloali'i, 1999;Balaraman, 2005). Ammouneh et al (2011) reported that Bt isolates are very toxic to Ephestia kuhniella, Phthorimaea operculella and Cydia pomonella larvae (Lepidoptera).…”

This study investigates the efficacy of 22 Syrian isolates of Bacillus thuringiensis (Berliner) (Bt) against Syringopais temperatella under laboratory conditions by feeding larvae on bacteria-contaminated barley leaves.The results indicated that all Bt isolates caused concentration and time related mortality, in which the highest mortalities were recorded at the highest concentration (original concentration), and at the latest time after Bt application(72 h).Mortality caused by all Bt isolates was significantly higher than mortality in the control. Isolate no. 1 gave significantly (P<0.05) the highest mortality percentage (73.3%) against the early larval instars. For the late larval instars, the isolates no. 21 and 22 were at bar with each other and gave significantly (P<0.05) the highest percentage of mortality (53.3%). Early larval instars were significantly (P<0.05) more susceptible to all concentrations of Bt isolates used than the late larval ones.In conclusion, the study showed that some of B. thuringiensis isolates tested in this study were pathogenic to S. temperatella.
