Revision of the genus Parachaitophorus Takahashi (Hemiptera: Aphididae: Drepanosiphinae), with descriptions of five morphs and biology of P. spiraeae (Takahashi, 1924) on Spiraea Cantoniensis (Rosaceae)

摘要

The aphid genus Parachaitophorus Takahashi, 1937 was reviewed. The morphological study and rearing experiment of P. spiraeae (Takahashi, 1924) and P. yamashitai Sorin, 1979 appearing on Spiraea cantoniensis (Rosacaeae) showed that the described morph of P. sikhotealinicus Pashtshenko, 1988 recorded from the Russian Far East corresponded to the fundatrix of P. spiraeae. Moreover, a field observation suggests that P. yamashitai should be treated as junior synonyms of P. spiraeae, and descrive five morphs and bilology of P. spiraeae appearing on S. cantoniensis.
