Table 1 The larvicidal activity (mean mortality ± standard error) of different concentrations of aqueous extract of the green berries of S. villosum on third instar larvae of S. aegypti. Student's t-test t = 29.42*, 5.5*, 17.0* (between 0.5% and 0.1%) 12.43*, 3.32*, 14.0* (between 0.5% and 0.2%) and 1.73*, 4.33*, 4.0* (between mortality in 0.5% and 0.3% plant extract at 24, 48 and 72 hours bioassay); * denotes significant (p < 0.05); table value = 2.92 at five degrees of freedom. M, mortality (%); SE, standard error.
