In addition, insecticidal activities of the origanum oil and
pulegone, (±)-camphor, and verbenone against Blattella germanica L.females were comparable to that of permethrin (0.05 mg/cm
2
) but
more pronounced than that of propoxur (0.18 mg/cm2
), as demon-strated by the 24-h LC50values (Jang et al., 2005).
