“…In Lebanon ‘ Ca . Phytoplasma asteris’ has been reported infecting the leafhoppers Euscelis incisus Kirschbaum and Psammotettix provincialis Ribaut (Choueiri et al, ) but it has never been associated to cixiids before. Similarly, it is the first report of the presence of ‘ Ca .…”

Almond witches'-broom (AlmWB) disease, associated with 'Candidatus Phytoplasma phoenicium', is an emerging threat with real risk of introduction in Euro-Mediterranean Countries. Its rapid spread over large geographical areas suggests the presence of efficient insect vector(s). In the present work, a survey on cixiids was carried out in Lebanon in the years 2010-2013 in AlmWB-infested almond and nectarine orchards. Insects were collected by means of different methods, identified with a stereo microscope, and analysed for phytoplasma identification through 16S rDNA PCR-based amplification and nucleotide sequence analyses. Preliminary transmission trials were performed with the most abundant species. A list of the cixiid genera and species present in the studied area is given as well as some information about their biology. 'Ca. Phytoplasma phoenicium' strains were detected in the genera Cixius, Tachycixius, Eumecurus and Hyalesthes. Preliminary trials revealed that Tachycixius specimens were able to transmit the detected strains to healthy peach potted seedlings. Further studies are required to better clarify the taxonomic status and the bio-ethology of collected planthoppers and deeply study their role as phytoplasma vectors.

Symptoms reminiscent of phytoplasma infection were observed in four provinces (governorates) of Egypt in fields of eggplants, tomato plants and squash. Diseased plants exhibited stunting, leaf yellows and flower development abnormalities. PCR amplification of 16SrDNA with phytoplasma-specific primer pairs confirmed the phytoplasma presence. Sequencing and phylogenetic analysis indicated that all phytoplasmas had the same partial 16SrDNA sequence, assigning them to the 16SrII-D phytoplasma subgroup. Disease incidence was about 1% among the 20 squash fields surveyed and equally varied from 4% to 15% in the 20 eggplant fields and in the 40 tomato fields inspected. The widespread distribution of this phytoplasma in annual solanaceous and cucurbit crops suggests a wider plant host range including wild plants that could act as reservoir and insist on the need for a insect vector survey. A finer genetic differentiation of Egyptian 16SrII-D phytoplasma strains from different geographical origins and different host plants should help to better trace such epidemics.

During autumn, an extensive survey was conducted in pepper (Capsicum annum L.) in intensive cultivation areas of four provinces in southeastern Turkey (Adana, Kahramanmaraş, Mersin and Şanlıurfa) in order to identify the causal agent (s) of phytoplasma‐like symptoms (chlorosis, little‐leaf, short internodes and stunting). DNA amplification by PCR and RFLP analysis using EcoRI restriction enzyme confirmed the presence of phytoplasmas in Şanlıurfa and Mersin, and consequently their possible association with the symptoms. Sequencing and phylogenetic analysis revealed that the isolate from Şanlıurfa had 99% sequence identity with “Candidatus Phytoplasma trifolii” (16SrVI) and is a member of the clover proliferation group (16SrVI‐A). Additionally, the isolate from Mersin had 96% sequence identity with “Candidatus Phytoplasma asteris” (16SrI). Importantly, gene sequence of the Mersin isolate shared <97.5% similarity to previously discovered “Ca. Phytoplasma” species. Consequently, the phytoplasma detected from Mersin could represent a new “Ca. Phytoplasma” species and to our knowledge, this is the first report of asteris‐like phytoplasmas infecting pepper in Turkey.
