Abstract:

A preliminary study of the host parasite relationship
between Tapinanthus bangwensis and its host,
Irvingia gabonensis
was carried out to gain an
understanding of the impact and outcome of their
co-habitation on the host plant. Assessment of the
physiological interaction was conducted via a study of some
of the physiognomy and reproductive capacity of infested and
uninfested hosts. The parasitic infestation it was observed
vary between adjoining locations of the host stands because
of differences in eco-habitat, physiognomy of susceptible
hosts and as well as the capacity of the interacting host
and parasitic plants to carry out their routine
physiological activities. The incidence of the parasitic
plant population on the host plantation in this study
indicated marginal loss in value of the conserved host
plants with correlated loss in productivity. Ultimately, the
presence of Tapinanthus on its Irvingia host
in this study would serve not only as a source of decline in
the conservation status and productivity of the host plants
but could also lead to the death of many susceptible hosts
if proliferation of the parasite is not kept in check.
