LARVICIDAL EFFICACY OF MATURE LEAF EXTRACT OF NICOTIANA PLUMBAGINIFOLIA VIV. (SOLANACEAE) AGAINST SOUTHERN HOUSE MOSQUITO
The small iniquitous fly mosquito is responsible for transmitting various deadly diseases, so it is inevitable to control mosquito vector population. Due to resistance of the synthetic insecticides, use of botanicals is a new trend to control the mosquito species. Present study was carried out to examine the efficacy of mature leaf extract of lessThan i greaterThan Nicotiana plumbaginifolia lessThan /i greaterThan on larval forms of filarial vector lessThan i greaterThan Culex quinquefasciatus lessThan /i greaterThan . All larval instars treated with crude and three different solvent extracts of lessThan i greaterThan N. plumbaginifolia lessThan /i greaterThan leaves. LC lessThan sub greaterThan 50 lessThan /sub greaterThan and LC lessThan sub greaterThan 90 lessThan /sub greaterThan values were determined by log-probit analyses. Statistical justifications were carried out through regression and ANOVA analyses. Cent percent larval mortality was found against 1 lessThan sup greaterThan st lessThan /sup greaterThan instar larvae at 0.20% concentration of crude extract and 60 ppm concentration of acetone solvent extract at 72h of post exposure. Non-target organisms were non-responsive to both crude and acetone solvent extracts. Thus, lessThan i greaterThan N. plumbaginifolia lessThan /i greaterThan may act as potential larvicidal agent against lessThan i greaterThan Cx. quinquefasciatus. lessThan /i greaterThan
