Cellulose-digesting bacteria were isolated from hindgut of Allomyrina dichotoma (Coleoptera: Dynastidae). The bacterial isolates were identified as Yersinia sp. and Bacillus sp. The addition of the identified bacteria to diet increased growth rate of the cetoniid beetle, Protaetia brevitarsis senlensis (Coleoptera: Cetoniidae), probably by digesting cellulose nutrient contained in the oak tree sawdust diet. An additive of wheat flour at more than 10% to the sawdust diet significantly enhanced growth of P. brevitarsis senlensis.
