Effect of Extracts of Datura stramonium L. (Jimson's Weed) on the Feeding Activities of Subterranean Termites (Macrotermes subhyalinus L.)

Field trials were conducted to study the bioefficacy of Datura stramonium L. against the deleterious activities of termites, Macrotermes subhyalinus L. (Isoptera: Termitidae). Ethanol, methanol, acetone, petroleum ether, and n-hexane extracts from the whole fruit of D. stramonium were applied to obeche wood (Triplochiton scleroxylon) to serve as a substrate. The extracts were tested at concentrations of 0.5%, 1.0%, and 1.5% with four replications each. A standard chemical (Basudin®) and an untreated control were also used. Results showed that the extracts were effective in reducing termite infestation, particularly at the 1.5% concentration, which showed similar efficacy to the Basudin® control.
