Pamphilius daisenus,an Oligophagous Sawfly Feeding on Spiraea japonica: The First Record of Pamphiliidae (Hymenoptera) Associated with Spiraea

摘要

Based on rearing experiments and a molecular analysis using the mitochondrial cytochrome oxidase subunit 1 (COI) gene sequences, Spiraea japonica L.f. [Rosaceae] is recorded as a host plant of Pamphilius daisenus Takeuchi, 1938. This is the first record of Spiraea as the host plant of the Pamphiliidae. Pamphilius daisenus is an oligophagous species feeding also on Arun- cus dioicus (Walter) Fernald var. kamtschaticus (Maxim.) H. Hara [Rosaceae].
