Present study was performed to evaluate the anti-termitic potential of four common plant species of Zingiber officinale, Raphanus sativus, Rosa indica and Aloe vera. During laboratory bioassay, the biological activity of ethanolic extracts of these plants was evaluated. The ethanol extract of Z. officinale caused highest mortality (100%) while least mortality (68%) was observed in R. indica extract. The LT50 for Z. officinale were 24.34, 40.40 and 64.7 h for concentrations of 10%, 5% and 3% respectively. Present findings suggested that these plant extracts can provide environmental friendly management of H. indicola. In A. vera, also resulted in significant mortality against H. indicola i.e. 94%, 64% and 44% on exposure of 10%, 5% and 3% concentraions. While LT50 were 34.66, 65.59, and 100.1 hours against 10%, 5% and 3% concentrations. In R. sativus, mortality of H. indicola was 76%, 50% and 30% while LT50 against were 59.10, 86.20, and 127.3 h, against concentration of 10%, 5% and 3%. Least mortality was observed in R. indica i.e. 68%, 44% and 30% while LT50 were 64.17, 94.58 and 125.5 h at 10%, 5% and 3% respectively. This study revealed that the extracts of Z. officinale, A.vera and R. Sativus have a potential to be used for termite control especially Heterotermes indicola to minimize the damage.
