POLLINATING FIG WASP AND SEED PRODUCTIONS OF Ficus deltoidea var. angustifolia AT SELECTED OIL PALM PLANTATIONS IN PENINSULAR MALAYSIA

Abstract

The relationship between Ficus deltoidea (family Moraceae)
and pollinator fig wasp (family Agaonidae) are extremely
specific in which each partner depends on the other for their
reproductive success. There are about seven described varieties
of Ficus deltoidea can be found in peninsular Malaysia. Ficus
deltoidea is a dioecious species that are primarily epiphytes.
They are unharmful for their host tree where one of the host tree
is oil palm tree. In this study, epiphytic Ficus deltoidea var.
angustifolia from oil palm plantations in Banting, Dengkil,
Changkat Lobak and Batu Pahat, Malayaia were studied to
determine the flower variation and reproductive output (fig
wasp and seeds) by the figs of different individual plants and
locations. A total of ten matured figs from each male and female
tree from all locations were collected and later dissected to 

count the number of flowers, galls, female and male fig wasp
for male tree while the number of seed and female flowers were
counted from female tree. Data were analysed by using one-way
ANOVA. Overall results showed that different individual plants
were significantly varied in their floral numbers and
reproductive output (pollinators and seeds) (P < 0.05) for both
and male figs except for seed productions at Changkat Lobak (P
= 0.067). Whilst there were significant different (P < 0.01) in
the production of pollinators and seeds by the figs among
locations. The reproductive output (pollinators and seeds) were
greatly influenced by number of flowers and number of fig
wasp visitations per fig.
