Further studies on citrus chlorotic dwarf disease

In the late 1980s, a new disease of citrus called citrus chlorotic dwarf was observed in the Eastern Mediterranean region of Turkey (see EPPO RS 94/209 and 97/014). It is causing serious losses within a limited area. Citrus chlorotic dwarf was considered to be caused by a virus transmitted by Parabemisia myricae. At first, natural spread was rapid, but recent surveys showed that it slowed down, as biological control of P. myricae was implemented. A survey was conducted in newly established orchards in the region of Icel. In total, 7,145 trees from 11 orchards were examined and an average infection rate of 7.8 % was found. During experiments, it was found that the virus is present only in low concentration in infected citrus plants and is very difficult to extract from infected tissues.
