Title
Scientific Opinion on the pest categorisation of Circulifer haematoceps and C. tenellus
EFSA Panel on Plant Health (PLH) EFSA Journal 2015. doi:10.2903/j.efsa.2015.3988
Other claims from this paper (14)
- Observation Circulifer tenellus and C. haematoceps are identifiable insect species using external morphology and male genitalia.
- Observation Both vectors are considered Old World natives; Ct also occurs in North America and the Caribbean.
- Observation Ch is reported in 11 EU Member States.
- Observation Ct is reported in Spain, France, Italy and Greece.
- Observation Neither vector is harmful itself, but both transmit Spiroplasma citri, which causes citrus stubborn disease.
- Observation Ct's major North American impact is transmission of Beet curly top virus to sugarbeet.
- Observation Ct transmits Candidatus Phytoplasma trifolii.
- Observation Ch transmits Ca P. asteris.
- Observation Ch and Ct are regulated EU harmful organisms for Citrus, Fortunella and Poncirus planting material despite broader host ranges.
- Mechanism Ch and Ct likely spread on planting material because eggs are laid in leaf veins and petioles.
- Observation Both vectors have been observed hitch-hiking on terrestrial vehicles.
- Observation Ct has very high flight capacity.
- Observation Both vectors have many hosts, especially Chenopodiaceae, Brassicaceae and Asteraceae.
- Observation Risk-area ecological conditions suit S. citri establishment and spread where citrus grows.
