Abstract

Termites are a group of eusocial Isoptera insects. They cause serious damage to wood, plants, crops and forest plantation. Control of termites is a major concern. In the present study, rhizome extracts from four different varieties belonging to Zingiberaceae family were selected and checked for their insecticidal potential. Aqueous, ethanolic and petroleum ether extracts of Hedychium coronarium, Maranta arundinaceae, Alpinia galanga and Acorus calamus rhizomes were prepared and tested. Different concentrations of the filtrate ranging from 1-5% were tested against termites and observed for 6 hours of exposure. The insecticidal effect was analyzed by observing and recording the death rate of termites. 1% ethanolic and petroleum ether extracts of Hedychium coronarium, Maranta arundinaceae and Acorus calamus caused around 30% and 50% mortality at 2 hour exposure and extract concentrations of the same rhizomes at 2%-5% caused 50-100% mortality in termites at various exposure periods. Whereas Alpinia galanga was most effective as an anti-termite agent, as 1% ethanolic and petroleum ether extracts of Alpinia galanga resulted in 90% mortality at 2 hour exposure and 2%-5% extract concentrations of Alpinia galanga caused mortality at the rate of 95-100% at various exposure periods, i.e., dose dependent mortality was observed when both ethanolic and petroleum ether extracts of all four plants were used.
