Larvicidal activity of the extracts from different parts of the plant Solanum xanthocarpum against important mosquito vectors in the arid region.

摘要: Larvicidal efficacy of the aqueous and methanol extracts from green unripe yellow ripe fruits, seeds, leaves roots plant Solanum xanthocarpum was evaluated against Anopheles culicifacies, stephensi, Aedes aegypti Culex quinquefasciatus, important mosquito vectors prevalent in arid region. Studies were carried out on late 3rd orearly 4th instarlarvae these species using standard WHO technique. Based concentration mortality data LC50 LC90 values along with their fiducial limits, regression equation, chi-square (chi2)/heterogeneity response have been determined bylog probit analysis. The 24 hr as observed for fruits 112.7, 498.2 846.3 mg l(-1) 104.7, 267.7and 832.2 quinquefasciatus respectively. However, formethanol seeds 51.6, 52.2, 118.3 157.1 66.9, 73.7, 123.8 154.9 above four vector results showed that larvae anophelines much more susceptible compared to culicines both tested. found 2-5 times effective extracts. calculated during analysis did not show any heterogeneity response. Experiments conducted this didn't larvicidal activity study would be great importance while formulating control strategy based alternative insecticides.
