The Japanese beetle ( Popillia japonica ) is a member of the scarab beetle family , originally from Japan .

features

Japanese beetles grow to about 1.5 centimeters long. The elytra are iridescent copper-colored . The head and thorax is green. The body is generally oval in shape, with the thorax wider than the abdomen .

History and damage

The Japanese beetle was originally native to Japan only. It was first spotted at a nursery in New Jersey in 1916 after being embarked in 1912.

After being brought in in 1912, the Japanese beetle quickly became a nuisance for the United States and Canada. It damaged over 300 species of plants, including roses, grapes, hops and tomatoes. In contrast, the beetle is hardly a problem in Japan due to its natural predators.

The species was found in the Azores in the early 1970s. Finds of the Japanese beetle were reported for northern Italy in July 2014. Another find was reported in June 2017 near the Italian border in Ticino, Switzerland. He was discovered in Stabio in October 2019 . With the aim of preventing its spread, an export ban was issued for soil and plant parts from the affected area. In Switzerland, besides the vines , the maize and stone fruit crops would also be affected by the beetle. For May 2014 an animal was found and published for Germany (North Rhine-Westphalia) as part of studies on the beetle fauna. It can be assumed that this find is an individual find and that no population has been developed. Whether the species has damaging potential in Central Europe is unclear and is being investigated - well-founded assumptions on this can be found in a publication written by Urban, Schulze and Zorn in 2019. In the same publication, a find of the Beetle for Bavaria is reported, which was made near Oberstdorf.

biology

The life cycle of Popillia japonica is about a year in most of the United States and two years in its homeland. The beetles themselves live for around 30 to 45 days. In the larval stage, the grubs can be easily identified by their V-shaped grid pattern.
