Identification of Host Kairomones from Maize, Zea mays, for the Maize Weevil, Sitophilus zeamais
Journal of Chemical Ecology, 2012 The maize weevil, Sitophilus zeamais, is an economically important pest of stored grains in tropical and subtropical regions of the world. The behavioral responses of adult S. zeamais to volatile organic compounds (VOCs) from maize seeds, Zea mays, were studied to identify semiochemicals used in host location and provide potential tools for managing ...

Loss Assessment of Stored Maize at Different Storage Durations and Maize Weevil Densities
European Journal of Nutrition & Food Safety, 2021 Aims: The extent of stored grain losses depends on varieties and duration of storage, and most of the quantitative losses are attributed to insect pest infestations. The study was conducted to determine the damage caused by Sitophilus zeamais on maize stored at different durations. Methodology: Sitophilus zeamais at four varying population ...
