The efficacy of salting sliced sweetpotato chips prior to drying in
reducing and (or) controlling damage levels of dried chips in storage by
Araecerus fasciculatus Degeer (Coleoptera: Anthribidae) was
Eight salt dosage rates on freshly sliced chips were evaluated.
Artificial infestation of dried chips with adult A. fasciculatus was
conducted. Gravid females were allowed to oviposit for one week and the
infested chips incubated until the F1 generation adults had all emerged
under prevailing environmental temperatures of 26.29 +- 1.19 deg.C and
relative humidity 68.96 +- 7.39 percent. The number, weight, and
generation time of A. fasciculatus that emerged varied significantly
depending on the salt dosage rates. Best results were obtained with
increasing salt dosage levels. Salt application rate at 2-3 percent is
recommended for on-farm validation.
