Japananus hyalinus – Wikipedia

Japananus hyalinus, the Japanese maple leafhopper, is a species of leafhopper of the subfamily Deltocephalinae and tribe Opsiini[2] (previously positioned in tribe Scaphytopiini). Believed to be native to japanese Asia, it has been carried with the commerce in cultivated maples and is now broadly present in Europe, North America and Australia.[3][4]


Feminine 5.5 mm lengthy (even 6.5 mm[5]), male 4.25 mm. Head involves an acute level, head and prothorax greenish yellow. Forewings translucent with reddish veins (paler in male). Within the resting place three slim beaded bands of purplish brown run roughly straight throughout the wings, incorporating some parts of the veins.[1]Scutellum yellow with darkish markings resembling the “frowny” emoticon ☹.

The eggs are inserted into the nodes of younger branches, making them very tough to detect in dormant planting inventory. There’s usually one technology per 12 months (two in Italy), with the eggs over wintering.[4] The nymphs are sharply pointed at each head and tail and are regularly yellowish.

Origin and unfold[edit]

The species was first described (as Platymetopius hyalinus) by Herbert Osborn in 1900, from specimens taken in Washington, D.C. Because it was unlikely {that a} native species would have remained undetected so lengthy, he recommended it was an launched species introduced in with unique crops.[1] This was confirmed in 1931 when P. W. Oman recognized Platymetopius hyalinus with P. cinctus, described by Shōnen Matsumura in 1914 and located in Hokkaido, Honshu and Kyushu.[5][6]

In 1931 Elmer Darwin Ball designated P. hyalinus as the sort (and, on the time, solely) species of a newly differentiated genus Japananus. Since then an extra 5 species have been positioned on this genus. Aside from hyalinus they’re all native to mainland Asia and present no tendency to main vary expansions.[7][8]

In North America J. hyalinus has been recorded from North Carolina within the south to Ontario within the north.[4] The primary European information, from Austria and Romania, have been printed in 1961, adopted by studies from Germany, the previous Czechoslovakia and Yugoslavia (1987), Bulgaria and Hungary (1989), France, Spain and northern Italy (1994), Slovenia (2002), Serbia and southern Russia (2003), Luxembourg (2010) and Poland (2012).[3] It was found in Australia in 1997.[9]

The standing of J. hyalinus in the UK is presently unsure. In 1999 two bugs have been discovered throughout inspections of imported Acer palmatum inventory that originated from South Korea. In August 2014 the insect seen within the taxobox above was photographed in Cambridge, the place the entire breeding cycle has been noticed.[4][10]

Host crops[edit]

In its Asian residence vary the host crops are Acer japonicum and A. palmatum. In different places it readily adapts to different maple species, which little question assists its unfold. In Europe the primary meals plant is area maple (Acer campestre),[3] and it has been recorded from field elder, Norway maple, sycamore, silver maple, Montpellier maple, Acer buergerianum, A. truncatum and purple maple.[4]

Financial impression[edit]

Leafhoppers are regarded with some suspicion by plant growers, each due to the extra load they place on plant metabolism and their means to behave as vectors for virus illnesses and phytoplasma illnesses reminiscent of flavescence dorée (FD).[11] As of 2014 J. hyalinus will not be identified to be a illness vector and its potential to trigger important injury is assessed as very small.[4]
