Vector control is a major challenge now-a-days when they became resistance against commonly available insecticides. As an alternative, preliminary laboratory evaluation of Azolla pinnata crude and chloroform: methanol solvent extract was carried out under laboratory trials for control of Culex quinquefasciatus. Crude and solvent extract (chloroform: methanol) extracts of A. pinnata leaves were examined for the larvicidal activity against all the larval instars (1st to 4th) of C. quinquefasciatus. Dose-dependent mortality assays were performed using the extracts. Further, determinations of LC50 and LC95 values were accomplished through log-probit analyses and regression analyses. The larvicidal activity was statistically justified through ANOVA analyses. Effects of the extracts were examined on non-target water fauna. Exposure to A. pinnata crude and chloroform: methanol extract increased the mortality of first to fourth-instar C. quinquefasciatus. All the graded concentrations showed significant (P |
