Sporulation-associated activation of Bacillus sphaericus larvicide.
Preparations of the larvicidal crystal from 46-h cultures of Bacillus sphaericus 2362 contain 125-, 110-, 63-, and 43-kilodalton (kDa) proteins (P. Baumann, B. M. Unterman, L. Baumann, A.H. Broadwell, S.J. Abbene, and R.D. Bowditch, J. Bacteriol. 163:738-747, 1985). The 63- and 43-kDa proteins, which have been purified, are not immunologically cross-reactive, and only the 43-kDa protein is toxi...
متن کاملEfficacy of Bacillus Sphaericus Strain Isolated from North East Region of India as Potential Mosquito Larvicide
Efficacy of Bacillus sphaericus strain GC subgroup IV (Bs) isolated from Assam, India as water dispersible powder formulation has been evaluated in laboratory and field conditions. Laboratory evaluation revealed that Bs, Spherix, ABG 6262 and Bti 164 (serotype H14) produced 90% mortality in Cx. quinquefasciatus @ 0.5, 0.6, 0.75, and 0.7 ppm respectively. In field trial Bs dosage @ 0.1 g/m2 in f...
متن کاملFate and persistence of Bacillus sphaericus used as a mosquito larvicide in dairy wastewater lagoons.
The fate and persistence of the mosquitocidal bacterium, Bacillus sphaericus, in dairy wastewater lagoons was evaluated in conjunction with trials of its larvicidal efficacy against Culex stigmatosoma. Two commercial formulations, BSP-2 (at 4.48 kg/ha) and ABG-6184 (at 2.24 kg/ha) gave about 90% reduction for up to 4 weeks, although surface water lost its insecticidal activity by 3 days posttre...
متن کاملDevelopment of a Bacillus sphaericus tablet formulation and its evaluation as a larvicide in the biological control of Culex quinquefasciatus.
This study aimed to analyze the final fermentation culture of Bacillus sphaericus 2362, standardize it and develop an active tablet formulation for use in urban mosquito breeding sites. It was performed in three phases: analysis and standardization of a B. sphaericus fermented culture; physical, chemical, and biological analysis of the active powder (solubility, residual humidity, particle size...
متن کاملPhlebotomine sand fly control using bait-fed adults to carry the larvicide Bacillus sphaericus to the larval habitat.
Sugar meals of plant origin are an important component of the sand fly diet. We show that sugar solution baits have potential as vehicles for phlebotomine sand fly control. In the laboratory, adult Phlebotomus duboscqi Neveu-Lemaire and Sergentomyia schwetzi (Adler, Theodor, and Parrot) that have consumed an aqueous sucrose solution containing Bacillus sphaericus Neide toxins and are subsequent...
