Treatment R of 10 mL wood vinegar mixed with 200 g maize maize kernel resulted in the highest mortality compared to other treaments at 10 and 20 days after incubation.These data indicated that, at the dose, WV was effective as an insect repellent, so the weevil did not find suitable food and eventually starved. However, its function as food storage fumigant was relatively low, as indicated by treatments S and T, although significantly different from the control.
