Common brown leafhopper

The common brown leafhopper, Orosius orientalis (Matsumura) (Hemiptera: Cicadellidae) 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 is a possible vector of Australian grapevine yellows. O. orientalis also transmits Tobacco yellow dwarf virus (TYDV genus Mastrevirus, family Geminiviridae) to beans, causing bean summer death disease and to tobacco, causing tobacco yellow dwarf disease.

Although some direct damage caused by leafhopper feeding has been observed, it is relatively minor compared to the losses resulting from disease.

Orosius

Paulus Orosius (/ˈpɔːləs ɔːˈroʊʒiəs/; born c. 375, died after 418 AD) — less often Paul Orosius in English — was a Gallaecian Christian priest, historian and theologian, a student of Augustine of Hippo. It is possible that he was born in Bracara Augusta (now Braga), then capital of the Roman province of Gallaecia. Although there are some questions regarding his biography, such as his exact date of birth, it is known that he was a person of some prestige from a cultural point of view, as he had contact with the greatest figures of his time such as Saint Augustine of Hippo and Saint Jerome. In order to meet with them Orosius travelled to cities on the southern coast of the Mediterranean Sea, such as Hippo Regius and Alexandria.

These journeys defined his life and intellectual output. Orosius did not just discuss theological matters with Saint Augustine; he also collaborated with him on the book City of God. In addition, in 415 he was chosen to travel to Palestine in order to exchange information with other intellectuals. He was also able to participate in a Church Council meeting in Jerusalem on the same trip and he was entrusted with transporting the relics of Saint Stephen. The date of his death is also unclear, although it appears to have not been earlier than 418, when he finished one of his books, or later than 423.
