Abstract
A preliminary study was conducted to observe
the larvicidal property of Trigonella foenum-graecum(methi) seed extract in 5
different solvents namely: ethanol, methanol, acetone, chloroform and tap water
from 3rd December 2023- 15th January,2024 in
the Vidyasagar College laboratory against Culex quinquefasciatus mosquitoes. Out of these 5 solvents Trigonella extract in acetone and methanol
showed highest larvicidal property at 400 ppm with percentage mortality of Culex
quinquefasciatus larvae at 100%. According to Lc50 values, the acetone
extract had highest mosquitocidal activity with dosage of 46.774
mg/L. According to Lc90 values then also acetone extracthad highest mosquitocidal activity with dosage of 144.54
mg/L.
