During a survey carried out in 1994/1995, impatiens necrotic spot tospovirus was found for the first time in Poland. The virus was detected on Schefflera actinophylla grown in commercial glasshouses. Review of Plant Pathology, 76(7), p 760 (5899).

Lopholeucaspis japonica (EPPO A2 quarantine pest) was found in Uttar Pradesh, in India. According to the authors, this is the first report of L. japonica in India.
