Abstract

Ceutorhynchinae weevils (Coleoptera, Curculionidae) intercepted at the Narita sub-station, Yokohama Plant Protection Station, Japan.

Abstract

We provided a list of 224 specimens belonging to 53 ceutorhynchine species (Coleoptera, Curculionidae), which were intercepted from 1984 to 2016 at the Narita Sub-station, Yokohama Plant Protection Station, Japan. The specimens examined were found by import inspections of vegetables and cut flowers from Africa, Europe, East Asia, Oceania, and North America. The dominant group is Ceutorhynchini, which has been intercepted continuously on vegetables from Europe and cut flowers from Africa. Interceptions of Ceutorhynchini weevils on European vegetables consists mainly of four species, Ceutorhynchus erysimi, C. obstrictus, C. pallidactylus, and C. picitarsis, all of which are well-known pests of crucifers, whereas the overwhelming majority of those intercepted on cut flowers from Africa are species of the genus Isorhynchus in a broad sense as currently understood, including many undescribed species. Further studies on European and African Ceutorhynchini are necessary to assess the risk to plant protection in Japan. In addition, we provided dorsal and lateral habitus images for each species.
