The ovary of the tick Amblyomma triste is classified as panoistic, which is characterized by the presence of oogonia without nurse and follicular cells. The present study has demonstrated that the oocytes in all developmental stages (I-IV) are attached to the ovary through a pedicel, a cellular structure that synthesizes and provides carbohydrate ...

Amblyomma triste Koch, 1844, the tick species most frequently involved in human bites in Uruguay, has been implicated as a vector of human rickettsiosis. Seasonal abundance of adult A. triste was examined by standard flagging at three sites where human tick bites and cases of the disease have been reported.

Amblyomma triste (Koch, 1844) (Acari: Ixodidae) ovaries: an ultrastructural analysis.
Experimental parasitology, 2007This study presents an ultrastructural analysis of the ovary of the tick, Amblyomma triste. The ovary of this species is of the panoistic type that is, without nursing and follicular cells. It is composed of a layer of epithelial cells forming a wall and of germinative cells that generate the oocytes which remain attached to the external margin of this

Vitellogenesis in the tick Amblyomma triste (Koch, 1844) (Acari: Ixodidae) Role for pedicel cells.
Veterinary parasitology, 2007This study presents new information on the vitellogenesis of the tick Amblyomma triste. In this species, the ovary consists of a layer of epithelial cells, which form the ovarian wall, oogonia and developing oocytes; and the pedicel, a cellular structure that synthesizes and provides yolk precursors for developing oocytes.

Abstract A nymph of Amblyomma triste Koch, 1844 was found on a bat Myotis albescens (E. Geoffroy 1806) (Vespertilionidae), captured in Cerro Pan de Azucar (34°47´S 55°13´W), Departamento Maldonado, Uruguay. A retrospective search of ticks from bats deposited in the Museo Nacional de Historia Natural, Montevideo, Uruguay, yielded seven larvae of ...

Systematic and Applied Acarology
The tick species that comprise the Amblyomma maculatum group (Acari: Ixodidae) are widely distributed in the Nearctic and Neotropical regions, ranging from the United States of America (USA) to Argentina. This group includes three species: Amblyomma maculatum, Amblyomma tigrinum, and Amblyomma triste, which parasitize a high number of vertebrates ...
