| Abstract | ||||
| Effects of hexane, ethanol and petroleum ether extracts of the black peper fruits, piper nigrum L., were studied on the dry-wood termite,C. brevis. The results indicated that the hexane extract has excellent efficacy against the insect. Hexane extract at 0.5% concentration induced 50% mortality, which dropped to 4.76 and 14.28% with ethanol and petroleum ether, respectively 2 days post-treatments. Mortalities reached 100.42.85 and 89.29% at 5% conc. of the above mentioned extracts, respectively. After 14 days, 0.5% conc. of ethanol and petroleum ether gave 67.77 and 65.56% mortality, respectively and both of them induced 100% mortality at 5% concentration. | ||||
