Abstract
Larvicidal activity of acetone and petroleum ether extracts of four plants Murraya koenigii, Coriandrum sativum, Ferula asafoetida, Trigonella foenum graceum and synthetic larvicides Fenthion and Temephos used alone and in combination was carried out against A. aegypti larvae under laboratory conditions. Optimum values were found out by using different concentrations of each plant (ranged 25 ppm-900 ppm) and both synthetic larvicides (ranged 0.01-7.5 ppm). The synergistic study was carried out by using 0.05 ppm of Temephos and Fenthion with 25ppm of M. koenigii, F. asafetida, T. foenum graceum and 100 ppm of C. sativum. All the plants showed potential synergistic activity although showed comparatively poor larvicidal activity when tested individually.
