Eserine was toxic to Formosan subterranean termite soldiers and workers at very low concentrations compared to tetrahydronootkatone. Toxicity of eserine on soldiers was greater than workers and that was linked with acetylcholinesterase activity and sensitivity. In contrast, workers were more sensitive to tetrahydronootkatone.
