Studies on ecology and control measures against the invasive wood-boring beetle Aromia bungii (Coleoptera: Cerambycidae)

概要

Invasive non-native species have become a global problem with the increased international trade
and transportation of goods and humans. Species unintentionally invade new regions in addition to
their original distribution and significantly impact region-specific ecosystems, agriculture, forestry,
fisheries, and human-living environments in invaded regions. Longhorn beetles are the most common
invasive wood-boring species. For example, the Asian longhorn beetle, which is native to Asia, has
spread to North America and Europe, wreaking havoc on maple, poplar, willow and a variety of broadleaf trees.
The red-necked longhorn beetle Aromia bungii (Faldermann 1835) (Coleoptera: Cerambycidae)
has recently invaded Japan, Germany, and Italy, causing severe damage to Rosaceae trees. The beetle
is indigenous to China and the surrounding countries, and the trees of Prunus spp. are the most
common hosts of this beetle. The beetle has been identified as a significant pest in fruit orchards,
including peach, plum, ume, and apricot, in China. However, the biology of A. bungii remains
unknown. In Japan, the primary hosts of A. bungii are flowering cherry trees (Cerasus spp.), peach,
plum, and ume. Host flowering cherry trees are planted everywhere in urban areas in Japan, which is
a significant difference from its native regions. Consequently, considerable impacts of A. bungii
infestation have been observed in on urban greenings, particularly flowering cherry trees. In these
areas, the development of effective methods for detecting A. bungii and effective control measures are
urgently needed to eliminate the target beetle.
This research was conducted in Osaka Prefecture, where A. bungii was first discovered in 2015
and flowering cherry trees were widely planted in urban areas. This research aims to uncover reliable
information for protecting flowering cherry trees from the invasive wood-boring beetle A. ...
