    (KNUST, 2019-01) Danson-Anokye Alexander
    ost-harvest maize insect pests are a serious constraint to food security and income generation in sub-Saharan Africa. Ten varieties of maize cultivated in Ghana were screened to ascertain their resistance to the maize weevil, Sitophilus zeamais L. to assist farmers select a variety that can withstand the attack of the insect during storage. The study was conducted at the insect laboratory of the Department of Crop and Soil Sciences of the Faculty of Agriculture, Kwame Nkrumah University of Science and Technology, KNUST, Kumasi. The Dodie Index of Susceptibility was used to group the varieties. Abeleehi, Omankwa, Abontem, and Adikanfo had indices less than 4 hence were classified as resistant. Weevils placed on Abeleehi produced the smallest number of progeny, had the highest median development period and lowest percentage seed damage and weight loss. Obatanpa, Aburohoma, Aburohemaa and Pan 12 were classified as moderately resistant whiles 10C8446 and 12C7636 were classified as moderately susceptible. Abeleehi had the best germination percentage with 12C7636 recording the lowest germination percentage after 90 days of storage. The resistant varieties, particularly Abeleehi can be recommended for S. zeamais management in maize especially for smallholder farmers in Ghana, whose seed can also be saved by farmers for planting in the subsequent season
