Downloaded on 23 August 2007. According to Blanco s book 1845 , Palaquium Philippense, one of the tallest forest trees is also known as Palacpalac. It evolved from the Pampango term Palakpalak, a name used in reference to malakmalak. Malakmalak is a tree reaching a height of about 25 meters and a diameter of about 80 centimeters. The leaves are usually 16 centimeters or more in length. The lower surfaces are about 1.5. centimeters in length, and are borne on long stalks in small clusters. The corolla is white, the calyx brown and velvety. this species is very common and widely distributed in primary forests at low and medium altitudes from northern Luzon to sounthern Mindanao. It is cultivated at the Lamao Experimental Station. The fruit of this species is oval, similar to chico in appearance, about 3 to 4 centimeters or more in length, with an edible pulp of good flavor, and contains a single seed. Blanco mentioned that the seeds yield limpid, odorous oil which is employed in food as an illuminant. It is also called Palaquium oleiferum Blanco, a species apparently confined to the Philippines.

To measure intensity, olfactometers introduce an odorous gas as a baseline against which other odors are compared. Many scientist use the term olfactometer to refer to a device used to study insect behavior in presence of an olfactory stimulus. It consists of a tube with a bifurcation with T or Y shape where an insect walks and decides between two choices, usually clean air versus air carrying an odor. This is why this device is also called dual choice olfactometer. ref Beavers JB, McGovern TP and Adler VE 1982 Diaprepes abbreviatus Laboratory and field behavioral and attractancy studies.
