| host plant determines the phytoplasma transmission competence of empoasca decipiens (hemiptera: cicadellidae). | phytoplasmas are phloem-restricted plant pathogens transmitted by leafhoppers, planthoppers, and psyllids (hemiptera). most known phytoplasma vectors belong to the cicadellidae, but many are still unknown. within this family, empoasca spp. (typhlocybinae) have tested positive for the presence of some phytoplasmas, and phytoplasma transmission has been proven for one species. the aim of this work was to investigate the ability of empoasca decipiens paoli in transmitting chrysanthemum yellows phyt ... | 2011 | 21510180 |
| Survey of leafhopper species in almond orchards infected with almond witches'-broom phytoplasma in Lebanon. | Leafhoppers (Hemiptera: Auchenorrhyncha: Cicadellidae) account for more than 80% of all "Auchenorrhynchous" vectors that transmit phytoplasmas. The leafhopper populations in two almond witches'-broom phytoplasma (AlmWB) infected sites: Tanboureet (south of Lebanon) and Bourj El Yahoudieh (north of Lebanon) were surveyed using yellow sticky traps. The survey revealed that the most abundant species was Asymmetrasca decedens, which represented 82.4% of all the leafhoppers sampled. Potential phytopl ... | 2011 | 21864154 |
| study of soybean leafhoppers fauna and an investigation on biology of dominant species empoasca decipienspaoli in karaj area. | the fauna of soybean leafhoppers and the biology of dominant species were investigated in karaj during 1992-1994. for identification of species the male genitalia and other taxonomic characters were used. in order to find the duration and number of nymph stages, leaf cages were used on the plants. a thermograph was used to study the effect of temperature on nymphal stages in greenhouse. to study biology of e. decipiens in field four cages prepared and the trials has done inside them, and weekly ... | 2005 | 16628902 |
