| dc.description.abstract | An insecticidal efficacy of AgNPs synthesized from aqueous leaf extracts of E. tereticornis (Et-AgNPs) and P. pinnata (Pp-AgNPs) was evaluated on muscid flies by in vitro assays at different concentrations. The highest mortality of 70.0 per cent was observed against the adult flies of S. calcitrans and M. domestica in Et and Pp-AgNPs, at 20 mg concentration after 24 hours exposure. The LC25(1.226, 1.073, 1.013 and 0.420, 0.203, 0.458), LC50(9.158, 9.218, 8.736 and 5.705, 6.482, 2.798) and LC90(467.65, 546.86, 523.49 and 809.5, 467.26, 86.99) values were observed for Et and Pp-AgNPs against all the adult flies, respectively. Et and Pp-AgNPs showed 75.0 and 85.0, 100.0 and 90.0 and 80.0 and 85.0 per cent of larval mortality for M. domestica, S. calcitrans and H. irritans irritans at 20 mg concentration after 48 hours exposure, respectively. The LC25(5.053, 0.0873, 1.5280 and 1.546, 1.166, 2.683), LC50(12.873, 2.294, 5.239 and 6.222, 3.508, 5.702) and LC90(76.086, 14.375, 54.485 and 87.715, 28.455, 23.871) values were indicated for all the three muscid larvae, respectively. The pupicidal assay indicated the highest per cent inhibition against S. calcitrans (45.0 and 40.0%) followed by M. domestica (30.0 and 30.0%) and H. irritans irritans (30.0 and 30.0%) at 8 mg concentration after 24 hours exposure for Et and Pp-AgNPs, respectively. The LC25(1.714, 0.412, 4.20 and 1.908, 3.00 and 4.757), LC50(6.270, 1.921, 30.386 and 28.229, 19.955 and 17.599) and LC90(73.675, 35.801, 62.32 and 4.719, 730.52 and 211.367) values were observed for Et and Pp-AgNPs against all the three pupae, respectively. Probit analysis revealed the significant effect with different concentration of AgNPs on adult, larvae and pupal mortality of muscid flies. The study indicated Et-AgNPs and Pp-AgNPs | |
