Anatomical and histological changes in internal organs of adult Tripodendron lineatum ; Gnathotrichus retusus and G. Ixodidae Role for pedicel cells.
The minimum time required after the copula is performed is seven days.
In these images, all structures seem to be surrounded by circulatory sinus in fact they were never shown in images of B. Results of studies in Amblyomma triste by de Oliveira et al.
In the present paper, the general objective is to consider the female genital system of this tick as a whole and to analyze the morphological and functional interrelations between different structures.
Spermatids suffer a capacitation inside the seminal receptacle in order to complete maturation; already mature cells are called spermiophores Fig.
Sistema Reprodutor Feminino
When not in use, the organ is retracted within the anterior region of the body near the capitulum. Dissection of tick specimens was performed with an original method 13 allowing rreprodutor faster and secure procedure that could be done in 10 to 15 minutes per tick with a great percentage of success and without loss of genital structure parts.
Functional analysis of metabolic and imnune proteins in the tick Ixodes ricinus by RNA interference. Full text available only in PDF format.
Morphological, histological, and ultrastructural studies of the ovary of the cattle-tick Boophilus microplus Canestrini, Acari: Cells very similar to the epithelial ones form the pedicels. Also, the sagittal sections, and in close up of the genital pore and the final part of the vestibular vagina can be seen in Fig.
The lobular accessory gland is also shown in Fig 12 ; it is an enlargement of the vestibular vaginal epithelium which produces a secretion for the initial waterproofing layer for the eggs and also it is the most likely source of the genital sex pheromone 4, On the contrary, in B. A contribution to the anatomy and histology of the brown ear tick Rhipicephalus appendiculatus Newman.
Copulation in ixodid ticks. In their lumens we could notice masses of cells that will originate spermatozoids. So, next photographs will represent an approach of the anatomical location of these shown structures in relation to these conventional lines. Histologic technic and practical histochemistry methods. A seminal receptacle, absent in argasids 3,4 as well as the uterus, open also in the cervical vagina.
It is a paired structure formed by globular or finger like sacs sometimes called horns and glandular tissue. The quality and resolution of images are remarkable because of the improvement by authors of a histological technique specially for arthropods and for the employ of an original procedure for feminine tract dissection that makes it easier and saves time avoiding technical complications.
The quality and resolution of images are remarkable because of the improvement by authors of a histological technique specially for arthropods. When oviposition begins, the swollen structure is projected forward by hydrostatic pressure, the finger-like processes are everted from the body 4.
Some serial slicing were performed transversely and other longitudinally in horizontal or in sagittal alarelho, this procedure permits a better comprehension of three-dimensional disposition of organs inside the arthropod. Oxford, ; pp. The anatomy and histology of the female genital system in Boophilus microplus are scarcely studied; only it is possible to refer to articles about oviducts and fertilization 8,9 and studies of the ovary by Saito et al.
The wax coat waterproofs the eggs and causes them to stick together 17 forming huge masses that also contribute to retard desiccation.
Regionalization of oviducts in Boophilus microplus Canestrini, Acari: Male introduces its chelicerae inside the female genital pore and then ejaculates into a sac, named ectospermatophore; inside itthere is another sac the endospermatophore full of inmature seminal cells named spermatids. The male copulatory organs result of transformations that take place in the inner surface on the palial membrane. The male takes the ectospermatophore with its chelicerae by the neck of the sac and introduces it into the female genital pore Assuring paternity in a promiscuous world: A pair of tubular accessory glands pours out their secretions at the level of the union of both cervical and vestibular vagina.
The ovary is composed by a layer of small epithelial cells with rounded nuclei surrounding the lumen, and oocytes in different developmental stages: Aos colegas e amigos que nos auxiliaram nas capturas dos animais: Figure 2 represents the same scheme 1 with vertical lines demarcating zones, in order to guide readers on the approximate location of a number of serial cuts.
