Abstract:Feeding indices for 31 plants species known as a food source for the Chinese rose beetle, Adoretus sinicus Burmeister (Coleoptera: Scarabaeidae), were determined in paired choice experiments using snap beans, Phaseolus vulgaris L. 'Hawaiian Wonder', as the standard. The amount of non structural carbohydrates in the tested plant species was quantified. The results indicate a relationship between feeding damage by the Chinese rose beetle and the non structural carbohydrate content in plant species leaves. Additional paired choice feeding tests were conducted using leaves of relatively less preferred plant species that were experimentally manipulated to increase the nonstructural carbohydrates and favored plant species that were manipulated to reduce the nonstructural carbohydrates present in the leaves. Although other factors are involved in host acceptability, the results of these tests confirmed that the Chinese rose beetle preferentially selects the leaves of host plant species that are relatively high in nonstructural carbohydrates as a food source.
