[Autogeny in bloodsucking biting midges of the genus Culicoides (Diptera: Ceratopogonidae)]. 1993

V A Isaev

The phenomenon of autogenity has been examined by means of different criteria both in nature and in laboratory in 25 blood-sucking species of the genus Culicoides, which were collected in Russia, Uzbekistan, Azerbaijan, Armenia, Georgia and Kazakhstan during 1979-1990 years. An autogenetic maturation of eggs has been observed in 6 species, and the absence of this phenomenon has been observed in 19 species. It is suggested, that autogenity or non-autogenity is a species characteristic of blood-sucking midges. The processus of autogenetic vitellogenesis takes the time from later pupa (more than 2 days of this stage) to earlier imago (lesser than 2-3 days of this stage).

D010053	Ovary	The reproductive organ (GONADS) in female animals. In vertebrates, the ovary contains two functional parts: the OVARIAN FOLLICLE for the production of female germ cells (OOGENESIS); and the endocrine cells (GRANULOSA CELLS; THECA CELLS; and LUTEAL CELLS) for the production of ESTROGENS and PROGESTERONE.

D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.

D013045	Species Specificity	The restriction of a characteristic behavior, anatomical structure or physical system, such as immune response; metabolic response, or gene or gene variant to the members of one species. It refers to that property which differentiates one species from another but it is also used for phylogenetic levels higher or lower than the species.

D014586	USSR	A country located from the Baltic and Black seas to the Pacific Ocean and, for a time including 15 Soviet Socialist Republics. The capital was Moscow.	Soviet Union,Union of Soviet Socialist Republics
D014818	Vitellogenesis	The active production and accumulation of VITELLINS (egg yolk proteins) in the non-mammalian OOCYTES from circulating precursors, VITELLOGENINS. Vitellogenesis usually begins after the first MEIOSIS and is regulated by estrogenic hormones.	Vitellogeneses
