The
experiment was conducted in the laboratory at the Bako Research Center,
western Ethiopia. Combinations of different rates of filter cake were
evaluated against the maize weevil in no choice situations. Each
experiment was laid out in a Randomized Complete Block Design with three
replications. The experiment was re-infested to evaluate the persistence
of the treatments 90 days after application. Data were collected on
percentages of adult weevil mortality, numbers and weight of damaged and
undamaged maize kernels, number of progeny weevils emerged, percentages
of grain damaged, grain weight losses and seed germination. Analysis of
variance showed significant differences among the treatments in all
parameters. The number of progeny weevils emerged, percentages of grain
damaged and seed weight losses in different rates of treatments were
significantly lower than that of the untreated check. Filter (Melkabam)
cake at 0.5% w/w and above showed significantly higher percentages of
mortality and lower weight losses than that of the other treatments both
after 90 and 156 days of infestation. With regard to seed germination, ,
significantly (P<0.05) higher percentages of seed germination were
recorded in all rates of filter cake, except for the 0.0625% w/w and the
untreated check following 156 days after treatments. It can be conclude
that filter cake (Melkabam) at 0.5% w/w and above can be used to protect
maize from the maize weevil. How to cite this article: Yuya AI (2017).
