Leafhopper is the common name for any species from the family Cicadellidae. These minute insects , colloquially known as hoppers , are plant feeders that suck plant sap from grass, shrubs, or trees.
Beet leafhoppers can infect about 300 plant species, including vegetable crops and weeds. Pinfold said the tiny bugs are 3.5 millimeters long and spend the winter in grasses of the foothills.
Red thread disease is a fungal infection found on lawns and other turfed areas. It is caused by the corticioid fungus Laetisaria fuciformis and has two separate stages. The stage that gives the infection its name is characterised by very thin, red, needle-like strands extending from the grass blade.
The leafhopper-infecting virus, Homalodisca coagulata virus-1 (HoCV-1, Dicistroviridae), has been shown to increase leafhopper mortality. [ 7 ] [ 8 ] The virus occurs in nature and is spread most readily at high population densities through contact among infected individuals, contact with virus-contaminated surfaces, and/or as an aerosol in ...
In North America the disease is transmitted from infected to healthy trees by the whitebanded elm leafhopper (Scaphoideus luteolus Van Duzee), the meadow spittlebug (Philaenus spurarius) and by another leafhopper (Allygus atomarius), although other insects are also suspected of being vectors. Transportation of nursery trees is another way for ...
Global warming has brought Argentina's corn farmers a dangerous new enemy: a yellow insect just four millimeters (0.16 inch) long that thrives in hotter temperatures and is threatening harvests of ...
The Auchenorrhyncha suborder of the Hemiptera contains most of the familiar members of what was called the "Homoptera" – groups such as cicadas, leafhoppers, treehoppers, planthoppers, and spittlebugs. The aphids and scale insects are the other well-known "Homoptera", and they are in the suborder Sternorrhyncha.
