چکیده کرم غوزه پنبه، Helicoverpa armigera Hübner (Lepidopter: Noctuidae) یکی از آفات مهم محصولات کشاورزی در غالب نقاط دنیا از جمله ایران میباشد. در این آزمایش اثرات زیرکشنده غلظت LC20 باکتریBacillus thuringiensis subsp. kurstaki Berliner روی لاروهای سن سوم کرم غوزه پنبه در شرایط دمایی 1 ± 26 درجه سلسیوس، رطوبت نسبی10 ± 65 درصد و دوره نوری 8 : 16 ساعت (تاریکی : روشنایی) در آزمایشگاه مورد برر...
متن کاملComplete Genome Sequence of Bacillus thuringiensis subsp. kurstaki Strain HD73
Bacillus thuringiensis is a Gram-positive bacterium that produces intracellular protein crystals toxic to a wide variety of insect larvae. We report the complete genome sequence of Bacillus thuringiensis subsp. kurstaki strain HD73 from the Centre OILB (Institut Pasteur, France), which belongs to serotype 3ab and is toxic to lepidopteran larvae.
متن کاملFacile autoplast generation and transformation in Bacillus thuringiensis subsp. kurstaki.
We describe a method for maximizing the rate of conversion of Bacillus thuringiensis subsp. kurstaki vegetative cells to osmotically fragile forms in the absence of exogenously added enzymes. Optimal generation of autoplasts occurred in 50 mM sodium acetate buffer (pH 7.0) at 37 degrees C with 10% (wt/vol) polyethylene glycol as an osmotic stabilizer. The maximum autolytic rate resulted in a co...
متن کاملGenome Sequence of Bacillus thuringiensis subsp. kurstaki Strain HD-1
We report here the complete genome sequence of Bacillus thuringiensis subsp. kurstaki strain HD-1, which serves as the primary U.S. reference standard for all commercial insecticidal formulations of B. thuringiensis manufactured around the world.
متن کاملEffect of midgut proteolytic activity on susceptibility of lepidopteran larvae to Bacillus thuringiensis subsp. Kurstaki
Bacillus thuringiensis (Bt) is the most effective microbial control agent for controlling numerous species from different insect orders. All subspecies and strains of B. thuringiensis can produce a spore and a crystalline parasporal body. This crystal which contains proteinaceous protoxins is dissolved in the alkaline midgut, the resulting molecule is then cleaved and activated by proteolytic e...
