Brief description

Stephanitis takeyai Drake & Maa, 1955 is a pest insect on plants of the genus Pieris, especially Pieris japonica, the Japanese andromeda. It originated in Japan with its host plant but has since been introduced to other areas of the globe. The andromeda lace bug is about 3 millimeters in length. It has a characteristic rounded pronotum, lacy black and white wings, and shiny gold highlighting. The bug produces mottling on the leaves of the plant, and heavy infestations can cause the leaves to drop in large numbers, stunting the plant’s growth. Both nymph and adult forms damage the leaves by piercing them to suck the juices, and leave dark frass on the undersides of the leaves. Damage is worst on plants that grow in full sun (Wikipedia contributors 2018).

“Stephanitis takeyai is an invasive Tingidae native to Japan. It was introduced to Europe in 1994 through the plant trade in the Netherlands with its feeder plant Pieris japonica (Aukema 1996). It reached Germany in 2002 (Baufeld 2002), Belgium in 2003 (Aukema et al. 2005) and France in 2004 (Streito 2006)” (Schneider 2020).

Status and distribution in Luxembourg

Stephanitis takeyai Drake & Maa, 1955 was first found on 24^th June 2019 in the kitchen of a private house in Roeser. The often open door of this kitchen communicates with a garden in which grows Pieris japonica (the Japanese andromeda), the host plant of the Andromeda lace bug (Schneider 2020: 100).

Risk assessment

ISEIA protocol

Following its discovery in Luxembourg in 2019, the species has been reassessed on 14^th September 2020 to C1 (3+1+1+1) by Christian Ries. Assessment before the appearance of the species in Luxembourg: C1 (3+1+1+1) (Ries et al. 2017: 69).

Harmonia+ protocol

Overall risk score 0,08 = (Overall Invasion score 0,37 x Overall Impact score 0,39) (evaluated by Jennifer Cross, Svenja Christian and Roland Proess).
