The minimum time required after the copula is performed is seven days. In Rhipicephalus sanguineusde Oliveira et al. Ixodidae and its potential significance for fertilization. Surrounding the vestibular vagina there is a glandular epithelium, the lobular accessory gland, found only in ixodid ticks 4. Rev Cub Med Trop. Transversal sections of vestibular vagina appear in Fig. The penis has a conjunctive muscular sheath that can be seen in van Gieson’s coloured preparations.

When not in use, the organ is retracted within the anterior region of the body near the capitulum. 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 The quality and resolution of images are remarkable because of the improvement by authors of a histological technique specially apareoho arthropods and for the employ of an original procedure for feminine tract dissection that makes hitologia easier and saves time avoiding technical complications.

Morphological characterization of the ovary and vitellogenesis dynamics in the tick Amblyomma cajennense Acari: In these images, all structures seem to be surrounded by circulatory sinus in fact they were never shown in images of B. There are some anatomical particularities in B.

Cells very similar to the epithelial ones form the pedicels. In the structure of the testis a great number of very small channels converges to a single one.

The histological structure of ovary with oocytes and pedicel cells is shown in jasculino 6 and 7. 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.

It is in communication with the cervical vagina by means of an epithelial folded muscular tube: 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.

Anatomical and histological changes in internal organs of adult Tripodendron lineatum ; Gnathotrichus retusus and G. Results of studies in Amblyomma triste by de Oliveira et al. The reprodutog bends its capitulum toward the female genital aperture and then introduces its chelicerae which protrude out of its shafts into the female genital pore 18,19, 20 ; both hypostome and palps briefly touch the surface of the female, receptors on the palps mediate pheromone perception, these sensilla are concentrated on the fourth segment of the palp on hard ticks The functional anatomy and histology of the reproductive system of some pilid gastropod molluscs.

Regionalization of oviducts in Boophilus microplus Canestrini, Acari: Amblyomma triste Koch, Acari: It is an organ only observed in ticks, it is located in the interior of the body cavity near the anterior end of the scutum 2,4. Unfed and partially engorged females were employed in the study.


Ovaryoviductsseminal receptacle and tubular accessory glands obtained by dissection of non-fed and fed, unmated and mated females are shown in Figures 34 and 5. Morphological, histological, and ultrastructural studies of the ovary of the cattle-tick Boophilus microplus Canestrini, Acari: Assuring paternity in a promiscuous world: 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.

Ixodidae Role for pedicel cells.


The wax coat waterproofs the masculjno and causes them to stick together 17 forming huge masses that also contribute to retard desiccation. In their lumens we could notice masses of cells that will originate spermatozoids.

Some serial slicing were performed transversely and other longitudinally in horizontal or in sagittal sense, this procedure permits a better comprehension of three-dimensional disposition of organs inside the arthropod.

Next transversal cuts Fig. Vitellogenesis in the jasculino Amblyomma triste Koch, Acari: It is conspicuous the likeness of the images in all photographs and this fact discards the possibility of being a histological technic artifact.

The structure of female genital system in Ixodidae consists of a single U-shaped tubular ovary in the posterior region of the body, paired and folded oviducts are in histolgia extremes of the ovary joint into a common oviduct or uterus.
