| The drawing shows a typical alimentary canal and the Malpighian tubules of a leafhopper. |
|
| The potato leafhopper is active during the summer months, and can cause severe yield and quality losses in alfalfa. |
|
| Try calling Waitrose to enquire over their stock of xucaneb robber frog or xylophagous leafhopper and see how far it gets you. |
|
| The design is that of the forewings of a brilliantly coloured Agrosoma leafhopper, found on bushes along streams. |
|
| This leafhopper also feeds on alfalfa and causes leaves to turn yellow and drop off. |
|
| There is cause for concern however about another insect, the potato leafhopper. |
|
| Potato leafhopper levels were very high in some parts of the province, compounding the effects of the dry weather. |
|
| The principal vector is the leafhopper Macrosteles fascifrons, in which the phytoplasmas are propagative. |
|
| Until recently, the insect mainly responsible for spreading Xylella in California was a leafhopper called the blue-green sharpshooter. |
|
| Fieberiella florii, a leafhopper, has been identified as a potential vector of the disease. |
|
| Potato stolbur phytoplasma is naturally dispersed over fairly large distances by its leafhopper vectors. |
|
| And the Anagrus species don't seem to cross over from the one to the other subspecies of leafhopper, interestingly enough. |
|
| Most species have fairly restricted ranges and plant hosts, although some, such as potato leafhopper are widespread and feed on many plant types. |
|
| Sooty Mould is known to grow on sugary exudates of aphids and on leafhopper droppings. |
|
| New seedings that had experienced high levels of potato leafhopper damage during 2004 also appeared more likely to be affected. |
|
| Surround may also provide some control of the following orchard pest, tarnished plant bug, obliquebanded leafroller, leafhopper, plum curculio and codling moth. |
|
| Potato leafhopper damage in alfalfa is frequently underestimated. |
|
| Economic losses occur before plant symptoms develop, so it is important to identify the presence of large leafhopper populations before the damage occurs. |
|
| Three new idiocerine leafhopper from Guyana with notes on ant-mutualism and subsociality. |
|
| The phytoplasma also infects the leafhopper vector where it multiplies and remains for the life of the insect, ensuring its transmission to susceptible feeding hosts of the leafhopper. |
|
|
|
| In contrast, potato leafhopper feeding causes yellowing of the leaves, first on the edges and eventually entire leaves, as well as characteristic downward cupping of leaves and shortened shoot internodes. |
|
| It is an epidemic disease characterized by its rapid spread within vineyards due to vine-to-vine transmission by a cicadellid leafhopper and a crisis-recovery-relapse disease cycle. |
|
| Another particularly dreaded disease is curly top, carried by the beet leafhopper, which interrupts the lifecycle. |
|
| No transmission occurs through leafhopper eggs or plant seed. |
|
| So we need another species of leafhopper to carry them over the winter. |
|
| When recordings of male leafhopper vibrational signals were played, spiders began homing in on the signal and searching for food. |
|
| On grapes, GWSS treatments also control the variegated leafhopper and western grapeleaf skeletonizer. |
|
| An unknown species of leafhopper was consistently on leaves of floating primrose-willow at the Lewisville Aquatic Ecosystem Research Facility, but was not identified. |
|
| They compared the chemistry and flavor profile of tea plants that encountered the tea leafhopper, the tea geometrid and the plant hormone methyl jasmonate. |
|
| Transmission experiments on coconut lethal yellowing disease with Deltocephalus flavicosta Stal, a leafhopper vector of periwinkle phyllody in Jamaica. |
|
| This study reports for the first time the isolation of a rod-shaped, gram-positive bacterium from the disease-spreading leafhopper Draeculacephala minerva. |
