This study was carried out to evaluate the effect of various feeds on body length, width, and weight, and larval mortality of white-spotted flower chafer (Protaetia brevitarsis seulensis Kolbe). The feeds , aloe, apple, banana, persimmon and sweet pumpkin were tested to measure the developmental parameters. The result showed that no any significant effect of feeds on the larval weight in the early. However, as larva get matured, the effects of feeds on the developmental parameters were found significantly varied. Weight of larvae, cumulative increase on body length and width, and body weight were also found increase in case of apple feeding. Lowest increment of developmental parameters were reported in banana feeding. Highest mortality (11.2%) was occurred in aloe, banana, persimmon and sweet pumpkin feeding. Lowest mortality (9.9%) rate was observed in apple. Feeds such as apple, sweet pumpkin, and aloe can be used as a optimum diet for mass rearing of P. brevitarsis seulensis in laboratory.
