Bioefficacy of Binary Combinations of Plectranthus Glandulosus Leaf Powder and Acacia polyacantha Wood Ash on Sitophilus zeamais Motschulsky (Coleoptera: Curculionidae)
- Wini Goudoungou Jean; Ndjonka Dieudonné; Suh Christopher; Nukenine Elias Nchiwan
- The maize weevil, Sitophilus zeamais is highly devastating and is regarded as the most cosmopolitan pest of stored maize grain across the tropics. Cheap, effective and environmentally friendly methods of reducing maize storage losses caused by this weevil are necessary to combat food insecurity, especially in sub-Saharan Africa. The insecticidal efficacy of binary combinations between wood ash from Acacia polyacantha and Plectranthus glandulosus leaf powder was assessed on S. zeamais regarding adult toxicity, progeny inhibition, suppression of population and reduction of damage. The masses of combined products were mixed with maize grain to constitute the contents of 5; 10; 20 and 40 g/kg to carry out the bioassays of toxicity within 1, 3, 7 and 14 days exposure, progeny production, population increase and grain damage. The binary mixtures of P. glandulosus leaf powder and A. polyacantha wood ash showed positive performances. The combination 50AP50PG was the most effective; it induced 100% mortality at its highest content (40 g/kg) within 14 days of exposure. The synergistic action was observed for combinations of A. polyacantha wood ash with P. glandulosus leaf powder for all the proportions. The combinations inhibited more than 80% of F1 progeny relative to the control except combination 25AP75PG which reduced progeny by 78.82%. The combination 75AP25PG inhibited almost completely the production of progeny (> 95 %). The population of S. zeamais was considerably suppressed by all combinations thereby reducing maize damage and weight loss. Considering the results of this study the binary combinations of A. polyacantha wood ash and P. glandulosus leaf powder could be used as a suitable substitute of synthetic insecticides since it is economical and environmentally friendly.
