T. Burdeos and D. P. Gapasin ABSTRACT Soil depth affected the degree of sweet potato weevil infestation. Highest weight of infested tubers was obtained from the control (without soil added) while the lowest weight was obtained at 26 cm soil depth. Weevil population in tubers showed a similar trend. No infestation was recorded at 29 …
