Termiticidal activity of oil from Jatropha curcas L. and Azadirachta indica A. Juss against Coptotermes sjostedti Holmgren (Isoptera: Rhinotermitidae)

Abstract

The use of 10 and 15 mL of J. curcas oil caused more than 90% mortality of C. sjostedti, after 96 h, kept wood consumption by the insect below 6.0% after 3 months, and these outcomes were similar to that of Solignum at the same concentrations. About 35.0–65.2% reduction in weight was observed among untreated woods from the tested woods, indicating their susceptibility to C. sjostedti attacks. Correlation analysis shows a significant (r > − 0.900; P < 0.0001) negative association between termite mortality and the rate of wood consumption.
