Abstract
This study was carried out in Faculty of Forest U. of K. from
December 2002 to March 2003.
The main objective of this study is to compare the efficacy of
the botanicals specifically neem oil (NO), neem Seed Kernel Powder
(NSKP), Eucalyptus leaf oil (ELO) with BHC (Benzyne Hexa
Chloride) and to determine the impact of these botanicals on
infestation by Sinoxylon senegalense Karsch and weight loss of
Acacia seyal (Talih) logs as a result of infestation.
NSKP at 30% had no significant effect either on number of
pores or on weight loss, but NSKP at 40% and at 50% significantly
reduced both the number of pores and weight loss of A. seyal as
compared to the control. ELO at 20% and NO at 20% significantly
reduced infestation by S. senegalense whereas at 10% both oils had no
significant effect as compared with control. The present study showed
that, at high doses, botanicals were as efficient as BHC, or even more
effective than it in controlling infestation by S. senegalense, specially
ELO at 15%; NO at 20% and ELO at 20%. Nevertheless, at low doses
of botanicals, BHC was more effective than all of botanicals used in
controlling infestation of A. seyal logs by S. senegalense.
The study revealed that NSKP at 40% and at 50% can be used
as a cheap and safe natural insecticide and as a substitute to BHC.
Also neem oil and eucalyptus oil at 15% and at 20% can be used as
insecticides and as a substitutes to BHC because they were effective,
safe and environmentally friendly.
