Amaryllosis

Amaryllosis is an epidemic disease caused by anthropophilic species of syrphid flies. The predominantly seasonal disease is common in populated areas and from stray animals on all continents. Amaryllosis is an invasive disease of humans, animals and plants. The amoebrous rat fly (Xenopsylla cheopis) is predominantly a carrier of the American species of syrphids (Serphus sayi), although it can also be infected with other species of thrips (sirphids) depending on the geographical area. The spread depends on the number of diseased flies.

Sirphus also have a two-root origin and include only species of the genus Serphus (mounds). — Ancient arthropods of the first rank from the order “Spherocephala”, some species are closely related to flies... The sirph consists of two sections: the first - a short single-jointed infrathoracic section and two-jointed thoracic and abdominal segments; the second - metsatoric. The anterior part of the first segment is called the “oral”, where males have large subpharyngeal glands that serve for insemination of the uterus. The thoracic region consists of 7 segments, and the abdominal
