The salivary glands of Anocentor nitens (Neumann,1897) occur in pairs and are located in the anterolateral region of the general cavity, with milky white color and approximately equal sizes. They consist of a secretory portion and an excretion duct. In some glandular acini, all the cells had a basophilic appearance they were stained by hematoxylin, whereas others presented cells with different staining affinities. In this work, we describe the variations observed in these glands during the feeding cycle of ticks [after feeding (0 h) and successively at 24, 48, 72, 96, 120, and 144 h]. The cells stained by hematoxylin were shown to be more reactive to Alcian blue, thus demonstrating the presence of acid glycosaminoglycans, whereas those stained using eosin presented weak or no reaction. A strong reaction was found by the use of the periodic acid-Schiff (PAS) technique, thereby suggesting the presence of glycogen and/or glycoconjugates containing hexose, confirmed by using salivary amylase before PAS, with partial destaining of the slides. Continuing presence of residual staining in these cells suggests the presence of glycoconjugates containing hexose. Cells with nuclei of circular outline and few granules (of different sizes) were found in type II acini, 72 h after collection. Type I acini presented wide lumina and walls composed of larger numbers of cells of cubic to cylindrical shape. The pronounced degranulation shown in this study over the course of the feeding cycle was associated with the release of substances for oviposition.

i\.I3STRACT. AVALlATION OF THE ANOMALOUS BEHAVIOR OF ANOCENTOR NITENS (NEUMANN) (ACARI: IXODIDAE), DURING THE NON PARASITIC PlIi\.SE. A newtcchniquewas dcvclop tostudy the anomalous behavior or non parasitic phase or Anocentor nitens on horsc host. From the total teleogines was still alive during ali experimental period, 89.1 % laided eggs on ear host. The eclosion index was 77.05 % with 80.0% or cclodibility. The preoviposition period and oviposition period was 3 to 17 days (4.92±0.73 days) and 16 to 41 days (24.38 ± 1.05 days), respectively. The incubation period was 26 to 48 days (34.94±2.92 days).1t was conrirmed that A. nitens teleogine could laid on ear or horse, whcn it was dettachment and a ractor impossibilited it down on ground.
