Abstract

<p>In 2015 the red-necked longhorn beetle (Aromia bungii), known as an invasive species damaging Rosaceae trees, was found in Osaka Prefecture. After that, there have been concerned about the expansion of the damaged area by the species in ornamental cherry trees. So, we investigated the basic information such as the damaged area and the damaged rate of cherry trees in this area to establish the effective future management strategies.</p><p>In the fixed-point survey between 2015 and 2018, the damaged rates in cherry trees were increased over years. From 2015 to 2018, the total rates of damaged cherry trees were increased from 11.2 % to 61.2 %, and those of dead cherry trees were from 0 % to 13.1 %.</p><p>In the extensive survey of the damage on cherries at 140 spots in the Minamikawachi area in Osaka Prefecture between 2017 and 2018, most damage was accumulated in a specific area. The damage was spread concentrically from the initial spot of invasion, and a few of enclosed damaged spots were also occurred. The migration distance of the adult beetle was estimated about 2 km on average and maximum 3 km in a year.</p>
