Jikradia is a genus of leafhoppers (family Cicadellidae). There are over 20 described species in Jikradia. [1] [2] [3]
A 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. Their hind legs are modified for jumping, and are covered with hairs that facilitate the spreading of a secretion over their bodies that acts as a water repellent and carrier of pheromones. They undergo a partial metamorphosis, and have various host associations, varying from very generalized to very specific. Some species have a cosmopolitan distribution, or occur throughout the temperate and tropical regions. Some are pests or vectors of plant viruses and phytoplasmas. The family is distributed all over the world, and constitutes the second-largest hemipteran family, with at least 20,000 described species.
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.
The superfamily Membracoidea of sap-sucking true-bugs includes two of the largest families within what used to be called the "Homoptera": the leafhoppers (Cicadellidae) and the treehoppers (Membracidae). The other families in this group are quite small, and have, at various points, generally been included as members within other families, though they are all presently considered to be valid, monophyletic groups. The relict family Myerslopiidae is restricted to New Zealand and South America while the Melizoderidae consist of two genera restricted to South America. The great diversity of Neotropical taxa suggests that the group originated in that region.
David Allan Young, Jr., was an American entomologist who specialized in the taxonomy of the Cicadellidae and authored a comprehensive treatment of the family with numerous genera and species described and named by him. This work in three parts Taxonomic Study of the Cicadellinae covered 292 genera.
Graphocephala is a large genus of leafhoppers, found from southern Canada to northern South America.
The common brown leafhopper, Orosius orientalis (Matsumura) is one of the most common species of Australian leafhoppers with a very wide host range. It is an important vector of several viruses and phytoplasmas worldwide. In Australia, phytoplasmas vectored by O. orientalis cause a range of economically important diseases including legume little leaf, tomato big bud, lucerne witches broom, potato purple top wilt, Australian lucerne and the insect is a possible vector of Australian grapevine yellows. O. orientalis also transmits Tobacco yellow dwarf virus to beans, causing bean summer death disease and to tobacco, causing tobacco yellow dwarf disease.
Deltocephalinae is a subfamily of leafhoppers. Deltocephalinae is the largest subfamily in the family Cicadellidae and is divided into 40 tribes, comprising over 925 genera, and over 6,700 described species.
Empoasca fabae belongs to family Cicadellidae and genus Empoasca within order Hemiptera. They are more commonly referred to as the potato leafhopper. In North America they are a serious agricultural pest. Every year millions of dollars are lost from reduced crop yields and on pest management. Crops that are impacted the most are potatoes, clover, beans, apples and alfalfa.
Spangbergiella is a genus of leafhoppers in the family Cicadellidae. There are at least 4 described species in Spangbergiella.
Agallia is a genus of leafhoppers in the family Cicadellidae. There are about 8 described species in Agallia. During courtship displays and mating, both males and females of the species A. constricta alternate in making ticking sounds.
Coelidiinae is a subfamily of leafhoppers in the family Cicadellidae. There are at least 8 tribes, 108 genera, and over 900 species in Coelidiinae.
Sibovia is a genus of leafhoppers in the family Cicadellidae. There are at least 30 described species in Sibovia.
Tylozygus is a genus of leafhoppers in the family Cicadellidae. There are about six described species in Tylozygus.
Xestocephalus lunatus is a species of leafhopper in the family Cicadellidae.
Acinopterus is a genus of leafhoppers in the family Cicadellidae. There are more than 30 described species in Acinopterus. The members of Acinopterus are widely distributed across North and South America. Acinopterus is the type genus of the tribe Acinopterini.
