"Candidatus Liberibacter solanacearum" (Lso) is an economically important pathogen of solanaceous crops and the putative causal agent of zebra chip disease of potato (Solanum tuberosum L.). This pathogen is transmitted to solanaceous species by the potato psyllid, Bactericera cockerelli (Šulc), but many aspects of the acquisition and transmission processes have yet to be elucidated. The present...
"Candidatus Liberibacter solanacearum" (Lso) has emerged as a serious threat world-wide. Five Lso haplotypes have been identified so far. Haplotypes A and B are present in the Americas and/or New Zealand, where they are vectored to solanaceous plants by the potato psyllid, Bactericera cockerelli (Šulc) (Hemiptera: Triozidae). The fastidious nature of these pathogens has hindered the study of th...
The tomato-potato psyllid Bactericera cockerelli (Sulc) (Hemiptera: Triozidae) is a pest of many solanaceous plants, including tomato (Solanum lycopersicum L.) and potato (Solanum tuberosum L.). In tomato, feeding by nymphs is associated with "psyllid yellows." B. cockerelli also vectors "Candidatus Liberibacter psyllaurous," an infectious bacterium that causes "vein greening" disease.

An attack of Lauritrioza alacris (Flor, 1861) (Hemiptera: Triozidae) was recorded in a commercial plantation bay laurel (Laurus nobilis L., Lauraceae) the municipality Dois Lajeados, Rio Grande do Sul state (RS), Brazil. The immature triozids induced galls on attacked leaves consisting thickened margins that became folded downward, forming an elongated tube-shaped roll sheltered immatures. All ...
طی بررسی هایی که در سال های90- 1387 بر روی بندپایان زیان آور پده در استان های تهران، خوزستان، اصفهان و خراسان رضوی صورت گرفت، برگ های حاوی گال های پسیل، از ایستگاه های انتخاب شده در رویشگاه های طبیعی گونه پده (populus euphratica olive) جمع آوری و در شرایط آزمایشگاه (درجه حرارت 26-24 و رطوبت 60-50 درصد)، داخل ظروف پرورش نگهداری شدند. حشرات کامل خارج شده، دو گونه egeirotrioza ceardi (bergevin) وe...
