Biolarvicidal activity of Peanibacillus macerans and Bacillus subtilis isolated from the dead larvae against Aedes aegypti - Vector for Chikungunya

摘要

Two bacterial species were isolated from dead mosquito larvae. They were identified as Peanibacillus macerans and Bacillus Subtilis. They were examined for their mosquito larvicidal activity against chikunguya vector Aedes aegypti (Diptera: Culucidae). The LC50 values of P. macerans and B. subtilis were recorded 70.99, 50*10⁶ cells /ml and 58.97, 49*10⁶ cells /ml for 24h and 48h, respectively. The LC50 value of the procured culture Bacillus thuringiensis subsp israelensis also detected. It was noted as 152.02 and 50*10⁶ cells /ml for 24hrs and 48hrs. A. aegypti was the most susceptible to B. subtilis. It has the highest relative susceptibility (RS) value.
