Abstract
Mosquitoes are linked to the spread of infections to people and other
vertebrates. Mosquitoes causes diseases like dengue, filariasis, and malaria.
Zoonotic arboviruses transmitted by mosquitoes such viruses are saint Louis
Encephalitis Virus, West Nile Virus and Eastern Equine Encephalitis Virus.
Chemical insecticides used in the environment to control Mosquitoes bring high
major issues like biomagnifications of Toxins through Food chain. Avoiding
these toxins, many scientists have developed Biopesticide from the Biological
sources. The present study was aimed to evaluate the Larvicidal activity of Streptomyces
griseus isolated from the Marine soil sample in Besant Nagar Sea
Shore, Chennai, Tamil Nadu, India. The Streptomyces sp. was isolated and
identified as Streptomyces griseus based on the Microscopic examination,
Plating on Culture medium and Biochemical tests. The identified Streptomyces
griseus was evaluated for its Larvicidal activity against Mosquito larva of
Aedes aegypti. The Streptomyces griseus was prepared in various
dilutions viz., 10-1, 10-3 and 10-5 and
used for the Larvicidal bioassay studies. The outcome of bioassay results that
shown a range in the high value of effectiveness that depending on the level of
exposure to the Streptomyces griseus. The Mortality rate was found to be
increase as the incubation time also increases, and then increased exposure
time for all dilutions of Streptomyces griseus. In conclusion, it
was observed that the Streptomyces griseus is an effective bio-larvicide
used to reduce or eradicate Mosquito larva and preventing Vector borne diseases.
