Abstract
Mosquitocidal activity of Naringi crenulata
(Maha vilvam) was tested against the fourth instar larvae of C.
quinquefasciatus and plant extracts to prepare different concentrations and
against larvicidal activity of C. quinquefasciatus mosquito vector. Perusal
of the data clearly indicated that maximum larval mortality in ethyl acetate
extract was recorded in C. quinquefasciatus mosquito at 24hrs.Values
were recorded in different concentrations of 500ppm, 250ppm, 125ppm, and
62.5ppm, the values in the percentage of larval mortality 78.50
2.71, 59.14±3.79,
37.37±6.20 and 21.35±5.35% and then LC50 (LCL-UCL), LC 90(LCL-UCL)
X2 values for 2.499(2.114-2.912), 6.271(5.423-7.606)0.293
respectively. Then the values in the percentage of pupal mortality in same
extract at 71.74±3.45, 53.34±2.21, 34.84±3.29 and 20.11±3.07% and then LC50
(LCL-UCL), LC 90(LCL-UCL) X2 values for2.826
(2.396-3.327), 7.098(6.037-8.865)0.186 and the values in the percentage of ovum
mortality in same extract at 73.34±7.45, 51.47±2.41, 30.51±3.65 and 21.36±4.71%
and then LC50 (LCL-UCL), LC 90(LCL-UCL) X2
values for values in 2.827(2.419-3.299), 6.849(5.877-8.421)0.374 respectively.
