Occurrence and Distribution of Rhinoncus sibiricus (Coleoptera: Curculionoidea) and Its Preference for Two Buckwheat Species in China.

ABSTRACT: Rhinoncus sibiricus Faust, a major pest of buckwheat, has invaded the buckwheat cultivation areas of China for years. This pest was first found in Russia in 1940, causing great damage during the entire buckwheat-growing season. In China, there are few records on R. sibiricus, and studies regarding pest damage on buckwheat are unknown. The occurrence and distribution of this species in China is still not clear. We therefore conducted field surveys for 6 yr to identify the distribution range and the degree of pest damage caused by R. sibiricus in the buckwheat-planting areas of China and tested its preference for two Fagopyrum species in common garden experiments. The results showed that R. sibiricus had a larger distribution range in the Northern rather than the Southern part of China, and
