Cyt1A from Bacillus thuringiensis synergizes activity of Bacillus sphaericus against Aedes aegypti (Diptera: Culicidae)

Article Abstract:

The Cyt1A protein from Bacillus thuringiensis increases the toxicity of Bacillus sphaericus toward Aedes aegypti more than 3,000-fold. This is important because even though B. sphaericus is toxic to Culex and Anopheles mosquitoes, it has little effect on A. aegypti.

Cyt1Ab1 and Cyt2Ba1 from Bacillus thuringiensis subsp. medellin and B. thuringiensis subsp. israelensis synergize Bacillus sphaericus against Aedes aegypti and resistant Culex quinquefasciatus (Diptera: Culicidae)

Article Abstract:

Combining Bacillus sphaericus with the Cyt1Ab1 or Cyt2Ba1 cytotoxins from Bacillus thuringiensis can overcome a mosquito's resistance to B. sphaericus alone. This combination suppressed resistance of Culex quinquefasciatus to B. sphaericus from greater than 17,000- to 2-fold.

Cyt1A of Bacillus thuringiensis delays evolution of resistance to Cry11A in the mosquito Culex quinquefasciatus

Article Abstract:

Various experiments were reported in which separate Culex quinquefasciatus populations were selected for 20 generations to recombinant strains of Bacillus thuringiensis that produced either Cyt1Aa, Cry11Aa, or a 1:3 mixture of these strains. The results indicated that Cyt1Aa is the principal factor responsible for delaying the evolution and expression of resistance to mosquitocidal Cry proteins.
