Culex quinquefasciatus 58.21 ± 4.2166.46–49.95285.70 ± 34.18352.70–218.708.31
Anopheles subpictus 28.95 ± 2.2233.312–2.60168.05 ± 23.56360.79–245.618.88

LC50: lethal concentration that kills 50% of the exposed larvae.
LC90: lethal concentration that kills 90% of the exposed larvae.
UCL: upper confidence limit; LCL: lower confidence limit; : chi-square.
df: degree of freedom significant at < 0.05 level.
