Table 2 Probit and regression analyses of mortality rates of early 3rd instar larvae of Culex vishnui group and Anopheles subpictus to different concentrations of bioactive compound isolated from mature leaves of Solanum nigrum

From: Larvicidal activity of phytosteroid compounds from leaf extract of Solanum nigrum against Culex vishnui group and Anopheles subpictus
