Larvicidal activity of temephos against Anopheles stephensi, Aedes aegypti and Culex quinquefasciatus 24 h post treatment.

Mosquito species (na = 375) LC50 (95% LCL-UCL) (μg/ml) LC90 (95% LCL-UCL) (μg/ml) LC99 (95% LCL-UCL) (μg/ml) χ2 (df = 4)
Anopheles stephensi 50.703 (44.643–106.710) 360.454 (316.010–429.602) 616.981 (519.594–783.284) 4.561 n.s.
Aedes aegypti 48.340 (26.114–92.328) 259.645 (227.412–305.259) 431.913 (370.118–542.836) 3.136 n.s.
Culex quinquefasciatus 146.133 (56.232–200.429) 590.233 (501.650–760.274) 952.290 (776.815–1304.658) 0.719 n.s.

na = total number of mosquitoes used per each species, 25 per replicate, three replicates were carried out, five concentrations were tested, LC50 = lethal concentration killing 50% of exposed organisms, LC90 = lethal concentration killing 90% of exposed organisms, LCL = 95% lower confidence limits, UCL = 95% upper confidence limits, χ2 = chi square (not significant, p > 0.05); df = degrees of freedom.
