Maize Leafhopper
''Cicadulina mbila'', the maize leafhopper, is a leafhopper species in the genus ''Cicadulina''. It is found in sub-Saharan Africa (Kenya, Tanzania and Uganda), the Middle East, West Asia and India. It is one of the vectors of the maize streak virus Maize streak virus (MSV) is a virus primarily known for causing maize streak disease (MSD) in its major host, and which also infects over 80 wild and domesticated grasses.

Theunis Johannes Naudé
Theunis is a Dutch masculine given name. Like Teunis, it is a derivative of Anthonius (Anthony). It is considered a diminutive form of Antonius, Anthonius used in Belgium, Netherlands, Suriname, South Africa, Namibia, and Indonesia. Theuns is a short form used in South Africa. Both Theunis and Theuns also exist as a patronymic surname.

Leafhopper
Leafhopper is the common name for any species from the family (biology), family Cicadellidae: based on the type genus ''Cicadella''. 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 Vector (epidemiology), 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. They belong to a lineage traditionally treated as infraorder Cicadomorpha in the suborder Auchenorrhy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cicadulina
''Cicadulina'' is a leafhopper genus in the tribe Macrostelini. ''Cicadulina'' species are vectors of the maize streak virus Maize streak virus (MSV) is a virus primarily known for causing maize streak disease (MSD) in its major host, and which also infects over 80 wild and domesticated grasses. It is an insect-transmitted pathogen of maize in the genus ''Mastrevirus' ..., a disease which is a sporadic but severe in sub-Saharan Africa. The cause is a geminivirus which is persistently transmitted by ''Cicadulina'' leafhoppers. The disease is also transmitted to '' Urochloa panicoides'', a fodder grass originating in Southern Africa. The maize orange leafhopper '' Cicadulina bipunctata'' has been reported to induce gall-like structures on maize in Japan.Recent Outbreaks of the Maize Orange Leafhopper Cicadulina bipunctata Inducing Gall-like Structures on Maize in Japan.

Maize Streak Virus
Maize streak virus (MSV) is a virus primarily known for causing maize streak disease (MSD) in its major host, and which also infects over 80 wild and domesticated grasses. It is an insect-transmitted pathogen of maize in the genus ''Mastrevirus'' of the family ''Geminiviridae'' that is endemic in sub-Saharan Africa and neighbouring Indian Ocean island territories such as Madagascar, Mauritius and La Reunion. The A-strain of MSV ( MSV-A) causes sporadic maize streak disease epidemics throughout the maize-growing regions of Africa. MSV was first described by the South African entomologist Claude Fuller who referred to it in a 1901 report as "mealie variegation". The development of conventionally resistant maize varieties has been a priority since the 1950s in Kenya, Nigeria, South Africa and elsewhere, with a good deal of success: however, there are several genes associated with resistance, and breeding is complex. Transgenically resistant or genetically modified maize variet ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Macrostelini
Macrostelini is a Tribe (biology), tribe in the Deltocephalinae subfamily of leafhoppers. Macrostelini contains 37 genera and over 300 species. The tribe has a cosmopolitan distribution. Some species in the genus ''Cicadulina'' are agricultural pests and transmit maize streak virus in Sub-saharan Africa.

Insects Described In 1924
Insects (from Latin ') are hexapod invertebrates of the class Insecta. They are the largest group within the arthropod phylum. Insects have a chitinous exoskeleton, a three-part body (head, thorax and abdomen), three pairs of jointed legs, compound eyes, and a pair of antennae. Insects are the most diverse group of animals, with more than a million described species; they represent more than half of all animal species. The insect nervous system consists of a brain and a ventral nerve cord. Most insects reproduce by laying eggs. Insects breathe air through a system of paired openings along their sides, connected to small tubes that take air directly to the tissues. The blood therefore does not carry oxygen; it is only partly contained in vessels, and some circulates in an open hemocoel. Insect vision is mainly through their compound eyes, with additional small ocelli. Many insects can hear, using tympanal organs, which may be on the legs or other parts of the b ...
