Records of Anoplophora glabripennis (Motschulsky, 1853) (Coleoptera, Cerambycidae) collected in Toyama Prefecture, central Japan in 2023
Full text linkDistribution and attacks on trees by Asian Long-horned Beetle Anoplophora glabripennis (Motschulsky, 1853) were surveyed in Toyama Prefecture in 2023. Fifty-eight individuals were confirmed at 21 sites between June 30 and October 14, 2023. Combining the results of previous studies and this survey, the following four points were revealed: this species is densely distributed in the plain between the Jinzû-gawa River and the Jôganji-gawa River; in the western part of Toyama, it is becoming established west of the Kureha-kyûryô Hills; in the southern part of Toyama, although its establishment has not been confirmed, dispersed individual has been observed in the mountains around Mt. Sarukura-yama; and in the eastern part of Toyama, it has invaded as far as Kamiichi-machi Town. Two adult individuals were collected at Botanic Gardens of Toyama on October 14, 2023, which was the latest record in Toyama for the last sighting of an adult individual. Attacks on Acer sp. by this beetle was confirmed during this survey. This is the first record in Toyama. Combining the results of previous studies and this survey, attacks on trees have been confirmed in five species in Toyama.departmental bulletin pape
Habitat status of Cryptotympana facialis (Walker, 1858) (Hemiptera, Cicadinae) in Toyama Prefecture, central Japan
Full text linkThe habitat status of Cryptotympana facialis (Walker, 1858) in Toyama Prefecture has been investigated. A review of various records shows that this species has been confirmed at a total of 16 sites in Toyama since the 1930s. The records were concentrated in coastal areas, where it is said that introduced species from outside the prefecture are often found, and on the plains, where there is a lot of logistics activity. Most of the records were of one or two adult males that were seen only once. Therefore, it was considered that there were no established sites within Toyama, and only dispersed individuals from distant areas or human introductions were often found. In Tsubame-no, Toyama City, cicada shells were found for the first time in Toyama Prefecture. Since this is a green area with many planted trees, it is thought that the eggs or larvae were artificially introduced along with the planted trees. Continued surveys will be required to determine if they will persist.departmental bulletin pape
