This study investigated the effect on body length, body width, body weight and mortality of larva white-spotted flower chafers(Protaetia brevitarsis seulensis) that the feeds as a secondary feed aloe, apple, banana, persimmon and sweet pumpkin being sold on the market. Weight of larvae increased the most in a sweet pumpkin 2,966 mg, and was followed by banana and persimmon. Weight increased in the aloe the control as the lowest in 2,179 ~ 2,127 mg. It fed the sweet pumpkin showed the highest cumulative increase of 240% in the body length then the persimmon was a cumulative increase of 232%. It fed the sweet pumpkin showed the highest cumulative increase of 254% in the body width and the lowest cumulative increase of 232% was the control. It fed the sweet pumpkin showed the highest cumulative increase of 240% in the body weight then the persimmon, banana, apple in order. Mortality showed most of the high mortality rate of 19.8% in the sweet pumpkin and apple and banana and the lowest mortality rate showed a mortality rate of 13.2% in the control. Although these results sweet pumpkin, persimmon and banana are expected higher utilization as a secondary feed, it should be reviewed in various feeding ways how to reduce the changes of the artificial breeding environment.
