Abstract
Seven compounds and fractions prepared from pandan leaves (P. amaryllifolius) were evaluated for repellent activity against Blattella germanica (L.) using a modification of the linear tract olfactometer. 2-Acetyl-1-pyrroline, pandan essence and the hexane-pandan extract were repellent (65-93 % repellency) at all concentrations tested; the acetone-pandan extract was attractive at increasing concentrations (minimum of 62 % attractancy); artificial pandan flavouring and the dichloromethane-pandan extract gave erratic results. Undiluted crude aqueous pandan extract displayed an attractancy of 62%. The potential of P. amaryllifolius as a natural and environmentally friendly pest management tool is discussed.
