- Abstract
Green technology based botanical pesticides are highly favoured and in-demand all over the world. The aim of this study was to evaluate the efficacy of solvent extracts of various parts of Jatropha curcas against termites (Microtermes obesi). No choice bioassay was performed with butanol, ether, hexane and methanol extracts of J. curcas leaves, root and bark against termites under controlled conditions (28 °C temperature and 80% relative humidity) for 48 h. Methanoiic root extract (0.5 and 0.25 g mL-1 concentration) was found to be most promising imparting 100% termite mortality in 48 h. Ether extract of leaf showed moderate toxicity (70%) followed by hexane extract of root and butanolic extract of leaf (66.6 % each) with 0.5 g mL-1 concentration after 48 h. The present study suggested that J. curcas and its parts have termiticidal potential and could prove to be an ecofriendly biopesticide. GC-MS analysis of methanoiic extract of J. curcas root, which confirmed the presence of fatty acids and terpenes, responsible for the termiticidal activity, has been reported for the first time. The bioformulations could be prepared using active component present in jatropha roots and may be successfully utilized in termite management.
