Abstract

Epicerura pulverulenta (African Moth)is one of the most important defoliator of
Terminalia ivorensis A. Chev. leading
to a great reduction in their production and yield potentials. The constant use
of chemicals to control these phyto-pathogens poses potential threats to human
health and the environment. A non–chemical control strategy such as the use of
botanicals would be a better alternative. Botanicals are readily available,
safe, efficacious and eco-friendly. This study was undertaken to investigate
the effect of Eucalyptus camaldulensis
Dehn. H
and Xylopia aethiopia (Dun. )
A. Rich
leaf extracts on the leaf gall bug disease of Terminalia ivorensis. The fresh leaves of both plants were blended
to fine liquid extracts by conventional maceration techniques using distilled
water. Prepared concentration (0.5-2.0%) of the extracts were then tested
against the development of the leaf gall bug of Terminalia ivorensis . Benomyl(3%) was used as insecticidal drug.
It was observed that the extract treatments had no significant effect expect
for table 5,6,and the control which showed a significant effect.

 

Keywords: Terminalia ivorensis, Eucalyptus Camalduleusis, Xylopia aethiopia and
Leaf gall bug.
