Résumé
Post-harvest losses are one of the major causes of food insecurity in the developing world. The present
study was planned to investigate the effect of neem seed and garlic bulb powders in control of maize weevil
and prolonged storage of the powders on their insecticidal activity. A 3x3 factorial experiment was laid in a
Complete Randomized Design (CRD) replicated two times. The result indicated that all the treatments have
shown high repellence against maize weevil at all amounts of treatments (5, 10, and 15 grams) in the whole
durations. However, there was no significance difference among 5, 10, and 15 grams for all the treatments
including neem seed, garlic, and combination of neem seed and garlic powders. Mean separation for maize
weevil mortality rate during 48 days of treatment of maize grain with different amounts of neem seed, garlic
and combination of neem seed and garlic powder was shown that there was no mortality of maize weevils
recorded for control (0gram). However, significant mortality was recorded for each treatments during 48
days of storage. The highest mean mortality rate was recorded for neem seed powder than for garlic
powder, and combinations of neem seed and garlic powders showing insecticidal property of neem leaves.
Maize weevil progeny emergence rate during extended duration of maize grain storage as treated by neem
seed, garlic, and combinations of neem- garlic leaf powders was indicated that the highest progeny
emergence rate was recorded for control group in all treatments. Only after 48 days that progeny
emergence was recorded for experimental groups. It can be concluded from the present study that neem
and garlic bulb powders could be used as effective insect repellents. Further studies are required to
evaluate the effectiveness of neem seed and garlic powders in expended storage period.
