Locally available inert materials including sawdust, coffee
husk and wood ash were evaluated at different proportions
against Sitophilus zeamais and Sitotrog cerealella in 2002
in Awassa National Maize Project entomology loboratory. The
experiment was laid out incompletely Randomized design (CRD)
in three replications. The insect pests were reared at
laboratory condition before introducing into each treatment
to obtain the same age group. Maize grain was disinfected to
eliminate undiserable field infestation in refrigerator at
–20C before using for experimental purpose. The Treatments
were 10%, 15%, 20% and 30% of coffee husk, 10%, 15%, 20% and
30% of saw dust, 10%, 15%, 20% and 30% of wood ash and 2% of
Pirimiphos-methyl as standard check and untreated control.
The efficacy of each treatment was evaluated with respect F1
progeny emergence of the pests, mean number of damaged
kernels and germination percentage of maize kernels. Coffee
husk and wood ash at all dosages were found to be effective
in controlling S. zeamais and S. cerealella. Wood ash at all
proportions gave the best control of the pests during the
study period. Wood ash and coffee husk at higher rates were
more effective in controlling the pests. Sawdust at all
dosages was not different from the untreated control in
controlling S. zeamais. However, sawdust at some dosages
showed superior performance against S. cerealella.
