Abstract:[Objectives]  To test the ecological services provided by pollinating insects in the fruit industry and solve the problems of insufficient pollinators and low fruit quality. [Methods]  The benefit of the presence of Osmia cornifrous (Rodoszkouski) and Apis mellifera ligustica Spin, the two main pollinating insects in apple and cherry orchards in eastern Shandong province, on apple and cherry yield, fruit quality, were measured over three consecutive years. We compared fruit set, vitamin C content, soluble solids, total sugar content, total acid content and fruit yield in 6 orchards with O. cornifrous and A. mellifera ligustica from 2015 to 2018. Orchards with normal pollination methods were the control. [Results]  We found that orchards with O. cornifrous and A. mellifera ligustica had higher fruit set, and the fruit from these orchards had higher vitamin C, total sugar and total acid levels, and higher solid-acid ratios. The pollinating efficiency of O. excavate was, on average, higher than that of A. mellifera. [Conclusion] Both O. excavate and A. mellifera provide important pollination services in apple and cherry orchards; both species increase fruit set, fruit yield and flavor. O. excavate is superior to A. mellifera because of its greater resistance to lower temperatures, higher pollination efficiency and simpler, lower input, management.
