Essaying some Plant Powders against Maize Weevil, Sitophilus zeamais (Motsch.), for Protecting Maize Grains from Damage
The experiment was conducted to essay the efficacy of five plant powders, camphor (Cinnamomum camphora L.), datura (Datura stramonium L.), jatropha (Jatropha curcas L.), lantana(Lantana camara L.) and moringa (Moringa oleifera L.) against maize weevil, Sitophilus zeamais. The effect of the powders were observed at different doses, 0.0 (Control), 3.0, 6.0 and 9.0g /100g of maize grains on oviposition, adult emergence and percentages of weight loss and damaged grains. The lowest number of laid eggs was recorded in datura treatment at 3.0g dose, where it was 6.33 eggs then decreased gradually by dose increase to attain 1.66 eggs at 9.0g. Adult emergence decreased significantly by increasing powders doses to attain 1.33, 3.00, 4.66, 13.33 and 21.00 for datura, jatropha, lantana, camphor and moringa powders at 9.0g dose respectively. The highest percentage reduction of eggs and adult emergence were recorded in datura treatment at 9.0g dose, where it was 95.38 and 97.52%; then decreased gradually by decreasing dose to attain 82.41and 83.22% at 3.0g respectively. The lowest percentage of weight loss and infestation at 3.0g/100 grams in datura were 1.92% and 2.66% in average; increasing dose to 9.0g/100 grams gave 0.70 and 0.66% in average, respectively.
