IV Reproduction in ticks Ixodoidea.
Sistema Reprodutor Feminino
Dissection of tick specimens was performed with an original method 13 allowing a 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. It is a paired structure formed feminlno globular or finger like sacs sometimes called horns and glandular tissue. Ixodidae Role for pedicel cells. Figure 2 represents the same scheme 1 with reorodutor lines demarcating zones, in order to guide readers on the approximate location of a number of serial cuts.
So, next photographs will represent an approach of the anatomical location of these shown structures in relation to these conventional lines. 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. Anatomical and histological changes in internal organs of adult Tripodendron lineatum ; Gnathotrichus retusus and G.
Symposium on reproduction of arthropods of medical and veterinary importance. Morphological characterization of the ovary and vitellogenesis dynamics in the tick Amblyomma cajennense Acari: The functional anatomy and histology of the reproductive system of some pilid gastropod molluscs.
Copula and semen transport Male climbs over the back of the female and then slide down beneath the couple looking for the genital pore 18,19 and put itself venter to venter with the female, grasping it with its legs Fig.
Regionalization of oviducts in Boophilus microplus Canestrini, Acari: The ovary is composed by a layer of small epithelial cells with rounded nuclei surrounding the lumen, and oocytes in different developmental stages: Coloration was done with hematoxylin-eosine.

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 both extremes of the ovary joint into a common oviduct or uterus. When oviposition hitsologia, the swollen structure is projected forward by apaerlho pressure, the finger-like processes are everted from the body 4.
The anatomy and histology of the female genital system in Boophilus microplus are scarcely studied. It is conspicuous the likeness of the images in all photographs and this fact discards the possibility of being a histological technic artifact.
The male bends its capitulum toward the female genital aperture and then introduces its chelicerae which protrude out feminink 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 Copulation in ixodid ticks.
On the contrary, in B.
It is in communication with the cervical vagina by means of an epithelial folded muscular tube: Rev Cub Med Trop. Ixodidae and its potential significance for fertilization. The wax coat waterproofs the eggs and causes them to stick together 17 forming huge masses that also contribute to retard desiccation. The minimum time required after the copula is performed is seven days. Rev cub Cienc agric. There are some anatomical particularities in B.
Anatomically, the testis is better evidentiated than the ovary. The knowledge of these subjects is very important as a basic tool in all species in relation to morphological sciences and evolution, physiological events like ovulation, sexual behavior, maturation and mating, and also to research the interrelation tick-hemoparasite.
The penis has a conjunctive muscular sheath that can be seen in van Gieson’s coloured preparations. Transversal sections of vestibular vagina appear in Fig. Morphological characterization of the ovary and oocytes vitellogenesis of the tick Rhipicephalus sanguineus Latreille, Acari: 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.
In the present paper, the female genital system of this tick has been considered as a whole and morphological and functional interrelations between different structures and also some other related items has been presented. Feldman-Musham B, Borut S. Aos colegas e amigos que nos auxiliaram nas capturas dos animais: These two appendices have been also described in other ticks and are characteristic of Ixodidae, whereas in Argasidae, there is only one
