Post-harvest evaluation of selected hybrids to maize weevil Sitophilus zeamais resistance

Sitophilus zeamais has been identified as one of the most destructive pests of maize stored in tropical regions. While most maize hybrids are being developed, it is necessary to evaluate their resistance to this pest. This study determined the resistance of selected maize hybrids to infestation by S. zeamais.

Efficacy of solvent extracts of Calpurnia aurea (Ait.) Benth and Milletia ferruginea (Hochest) Baker leaves against maize weevils, Sitophilus zeamais (Motsch.) of stored maize in Ethiopia

Distilled water, acetone and ethanol (polar solvent) extracts from 20 g/100 ml and 30 g/100 ml levels of extraction of Calpurnia aurea and Milletia ferruginea were tested as protectant against maize weevils in maize grains under laboratory condition. They were applied at a rate of 10 and 15% (w/v) in admixture bioassays from both of the aforementioned extraction levels. Parental weevil’s mortality, F1 progeny...
