Abstract EN
The bio-efficacy of Aloe vera leaf extract and bacterial insecticide, Bacillus sphaericus larvicidal activity was assessed against the first to fourth instars larvae of Aedes aegypti, under the laboratory conditions.
The plant material was shade dried at room temperature and powdered coarsely.
A.
vera and B.
sphaericus show varied degrees of larvicidal activity against various instars larvae of A.
aegypti.
The LC50 of A.
vera against the first to fourth instars larvae were 162.74, 201.43, 253.30 and 300.05 ppm and the LC90 442.98, 518.86, 563.18 and 612.96 ppm, respectively.
B.
sphaericus against the first to fourth instars larvae the LC50 values were 68.21, 79.13, 93.48, and 107.05 ppm and the LC90 values 149.15, 164.67, 183.84, and 201.09 ppm, respectively.
However, the combined treatment of A.
vera+ B.
sphaericus (1:2) material shows highest larvicidal activity of the LC50 values 54.80, 63.11, 74.66 and 95.10 ppm; The LC90 values of 145.29, 160.14, 179.74 and 209.98 ppm, against A.
aegypti in all the tested concentrations than the individuals and clearly established that there is a substantial amount of synergist act.
The present investigation clearly exhibits that both A.
vera and B.
sphaericus materials could serve as a potential larvicidal agent.
Since, A.
aegypti is a container breeder vector mosquito this user and eco-friendly and low-cost vector control strategy could be a viable solution to the existing dengue disease burden.
Therefore, this study provides first report on the mosquito larvicidal activity the combined effect of A.
vera leaf extract and B.
sphaericus against as target species of A.
aegypti
