Abstract
In the present study, various concentrations of seed extracts of medicinal plants (Mentha arvensis
(mint), Ocimum bacilicum (niazbo), Psyllium ovata (harmal), Cichorium intybus (kasni)) were used against
Coptotermes heimi soldiers to see their impact on survival. The seed extract of M. arvensis caused highest
mortality i.e., 100%, 99% and 98% at 10%, 5% and 3% concentration. Cichorium intybus seed extract showed
92%, 88% and 85% mortality at 10%, 5% and 3% concentration. Ocimum basilicum extract demonstrated 80%,
78% and 76% mortality at 10%, 5% and 3% concentration. Psyllium ovata extract was least effective and caused
72%, 70% and 68% mortality at 10%, 5% and 3% concentration respectively. LT50 values for M. arvensis were
0.91, 0.94 and 1.13 hours for 10%, 5% and 3 % concentrations respectively. In case of O. basilicum, LT50 values
at 10%, 5% and 3% concentrations were 4.3, 4.6 and 4.8 hours respectively. LT50 values for P. ovata were 5.7,
6.2 and 7.1 hours for 10%, 5% and 3% concentrations. In case of C. intybus, LT50 values were 2.4, 2.8 and 3.4
hours at 10%, 5% and 3% concentrations respectively
