| Potato stolbur phytoplasma is naturally dispersed over fairly large distances by its leafhopper vectors. |
| The principal vector is the leafhopper Macrosteles fascifrons, in which the phytoplasmas are propagative. |
| The design is that of the forewings of a brilliantly coloured Agrosoma leafhopper, found on bushes along streams. |
| Potato leafhopper levels were very high in some parts of the province, compounding the effects of the dry weather. |
| Try calling Waitrose to enquire over their stock of xucaneb robber frog or xylophagous leafhopper and see how far it gets you. |
| The drawing shows a typical alimentary canal and the Malpighian tubules of a leafhopper. |
