| dc.description.abstract | Infestation of cereals in storage by Sitophilus oryzae, Sitophilus granaries and Sitophilus Zeamais lead to great food loses in Sub-Saharan Africa. Some of the synthetic pesticides which are available are non-biodegradable and have adverse effect on the environment and humans. Previous studies show that plant extracts have the potential for use as pesticidal agents against the weevils. The use of plant extracts in pest management is preferred because they are readily available and chances of drug resistance are low. The aim of this study was to collate and review the fragmented information on essential oils from plants with pesticidal activity against S. zeamais, S. oryzae and S. granaries and present recommendations for future research. Peer-reviewed articles were retrieved from Scopus, Science Direct, SciFinder and Google Scholar. This study led to identification of 196 essential oils extracted form plant species belonging to 31 plant families. Essential oils from the Lamiaceae family are the most studied, followed by Myrtaceae, Asteraceae, Apiaceae, Lauraceae and Piperaceae families. Insecticidal activity studies of the essential oils were mostly tested against S. zeamais (115 essential oils) followed by S. oryzae (58 essential oils) and S. granaries (23 essential oils) which suggests that S. zeamais is the most rampant and the most dreaded species. Future studies aimed in isolating and characterizing the active compounds from the essential oil is necessary. It is also necessary to develop effective formulations for controlling the pests | en_US |
