The Panel on Plant Health performed a pest categorisation of Hishimonus phycitis (Hemiptera:
Cicadellidae) for the EU. H. phycitis is a well-defined species, occurring in tropical and subtropical Asian
countries from Iran to Malaysia. H. phycitis is polyphagous. Hosts of particular relevance to the EU
include Citrus spp. and Solanum melongena. While harmful in its own right as a leafhopper extracting
host nutrients through feeding, it is regarded in the Middle East more significantly as a vector of
Witches’ broom disease of lime phytoplasma, which limits production of Citrus aurantifolia, and in India
as a vector of brinjal little-leaf phytoplasma impacting S. melongena yields. H. phycitis is currently
regulated by Council Directive 2000/29/EC, listed in Annex II/AI as Hishomonus phycitis (sic). Eggs
planted on host plants for planting could provide a pathway for entry into the EU. The EU has ecoclimatic
conditions that are also found in countries where H. phycitis occurs although it is unknown
whether H. phycitis occurs in those areas. There is therefore considerable uncertainty around EU
establishment. Any establishment is likely to be limited to the warmest areas around the Mediterranean.
As a free-living organism with adults capable of flight, spread within the EU would be possible but
confined to the limited area where establishment could occur. Measures are available to inhibit entry via
traded commodities (e.g. prohibition on the introduction of Citrus plants for planting; sourcing other
hosts from pest free areas). H. phycitis does satisfy all of the criteria that are within the remit of EFSA
to assess to be regarded as a Union quarantine pest. It is uncertain if eggs of H. phycitis would carry
phytoplasmas into the EU as transovarial transmission from infected females to eggs has not been
demonstrated. [-]
