    HARVESTING TECHNIQUES IN TAPPING PHILIPPINE RESINS WITH EMPHASIS ON ALMACIGA (AGATHIS PHILIPPINENSIS WARB)

    Arsenio B. Ella1

    The tapping practices on five resin producing species in the Philippines, namely, Dipterocarpus spp. for balau resin, Palosapis (Anisoptera thurifera ssp. thurifera) for oil of palosapis, Canarium spp. for Manila elemi resin, Benguet Pine (Pinus insularis Endl.) for oleoresin, and almaciga (Agathis philippinensis Warb.) for Manila copal resin, are discussed, including the potential of the resins as an export winner for the country.

    Because of economic importance, demand and availability of suitable trees for tapping purposes, emphasis is put on almaciga. The biological considerations in tapping to promote sustained resin production, the traditional method of tapping in the Philippines, and the improved tapping techniques developed by FPRDI for almaciga are explained.

    Keywords: Almaciga tapping, almaciga resin, Manila copal
