Abstract
The protection of stored agricultural products against insect pest attack is essential for safe and steady supply of high quality food. In an attempt to find alternative to synthetic insecticides control measure an experiment was conducted in the Pest Management laboratory of Crop, Soil and Pest Management Technology Department of Rufus Giwa Polytechnic, Owo, Nigeria to evaluate the potential of Mormodica charantia for the control of Sitophilus zeamais (Mots.) infestation in storage. The experiment was laid out in Completely Randomized Design (CRD) and replicated three times. The plant powder was tested at 0.5g, 1.0g, 1.5g and 2.0g per 20g of maize seeds to evaluate its ability to suppressed the population of S. zeamais and reduce seed damage of stored maize seeds. The plant powder resulted in effective protection in treated seed comparable to control experiment. There were significant low percentage seed damage and weight loss in seeds treated with M. charantia leaf powder. Total number of adult weevil emergence was least in treated grains at 2.0g dosage rate compared to other treatment dosages. This study shows that it is possible to use M. charantia to protect maize against S. zeamais infestation in storage in the context of sustainable pest management in organic agriculture. At present, there is scanty report on insecticidal activities of M. charantia against stored product pests. Therefore, this experiment was carried out to determine the possible insecticidal activities of the leaf essential oil of M. charantia on S. Zeamais.
