Bioefficacy of pectolinaringenin from Clerodendrum phlomidis Linn. F. against Anopheles stephensi and bhendi fruit borer, Earias vittella fab.

Larvicidal activity of pectolinaringenin from Clerodendrum phlomidiswas evaluated against Anopheles stephensi and antifeedant, larvicidal and growth inhibitory activities were evaluated against Earias vittella. Pectolinaringenin exhibited larvicidal activity of 100 and 98.24% against 2nd and 4th instar larvae of Anopheles stephensi at 5ppm concentration. It exhibited LC50 values of 0.35 and 0.55 ppm for 2nd and 4th instar larvae, respectively. At 100 ppm concentration, pectolinaringenin exhibited maximum antifeedant activity of 74.00% and larvicidal activity of 89.98%. The LC50 values were 36....
