Bacillus thuringiensis subsp. israelensis is the leading biopesticide in world due to its specificity and lack of toxicity. The use Bti still restricted developing countries bioprocess complications high cost production. In present study we have shown that lignocellulosic agro waste residues like rice straw can be used as effective substrates with appropriate chemical treatment methods. We comp...

BACKGROUND Bacillus thuringiensis is the most successful biological control agent used in agriculture, forestry and mosquito control. However, the insecticidal activity of the B. thuringiensis formulation is not very stable and rapidly loses its biological activity under field conditions, due to the ultraviolet radiation in sunlight. Melanin is known to absorb radiation therefore photo protecti...

In this study, the biological control activities of bacteria strains, which have been isolated from volcanic, sandy, salty soils and Ebu Cehil plant Calligonum polygonoides L. subsp. comosum (L’Hér.) were investigated against isolates Rhizoctonia solani causing root rot in beans. As result isolation, 83 strains obtained identified by biochemical tests fatty acid methyl esterase analyses. vitro ...

Levels, genetic traits and stability of resistance to Bacillus thuringiensis of the Bang Bua Tong (BS) population of the diamondback moth Plutella xylostella collected in Thailand were investigated. The BS population exhibited 668 and 66.5-fold resistance to formulations derived from B. thuringiensis subsp. kurstaki (Toarow CT®), and B. thuringiensis subsp. aizawai (XenTari®), respectively. In ...

A population (SERD3) of the diamondback moth (Plutella xylostella L.) with field-evolved resistance to Bacillus thuringiensis subsp. kurstaki HD-1 (Dipel) and B. thuringiensis subsp. aizawai (Florbac) was collected. Laboratory-based selection of two subpopulations of SERD3 with B. thuringiensis subsp. kurstaki (Btk-Sel) or B. thuringiensis subsp. aizawai (Bta-Sel) increased resistance to the se...
