The use of plant extracts as pest control is beneficial over synthetic pestidides because of their easily degradable, effective and ensure safety of the consumers and the environment. This study was aimed to examine the effect of ground funnel seed and koseret leaf in control of maize weevil and prolonged storage of the powders on their insecticidal activity in stored maize grains. A factorial experiment was laid in a complete randomized design replicated twice. The treatments have shown high repellence against maize weevil at all concentration of treatments. Mean separation for maize weevil mortality rate at different concentrations of fennel seed, koseret leaf and their combination powders resulted with no mortality. The highest mean mortality rate was recorded for fennel seed. Maize weevil progeny emergence rate during extended duration of maize storage as treated with fennel seed, koseret leaf, and their combination powders showed the highest progeny emergence rate in control group in all treatments. This study revealed insect repellents and pesticidal activity of fennel seed, koseret leaf powders and their combinations. Characterizing their effect in control of maize weevil and prolonged storage of the powders on their insecticidal action is crucial in protection of grains at a minimum cost.
