Strategic control of cattle ticks: milk producers' perceptions

Revista Brasileira de Parasitologia Veterinária/Brazilian Journal of Veterinary Parasitology (2011)

Maria Alice Zacarias do Amaral Christiane Maria Barcellos Magalhães da Rocha João Luiz Horácio Faccini John Furlong Caio Márcio de Oliveira Monteiro

In order to evaluate milk producers' knowledge about tests on tick sensitivity to acaricides, efficiency tests and strategic control, questionnaires were delivered to 670 producers. From these, 163 responses were received. These producers had sent ingurgitated female ticks to be subjected to tests on tick sensitivity to acaricides at Embrapa between 2001 and 2005. Most of the completed questionnaires came from the State of Minas Gerais, Brazil. After descriptive analysis and correlation of variables, it was found that 48.5% of the properties owned herds of up to 100 head of cattle and 57.3% of the producers belonged to a cooperative. Among the respondents, 157 (98.7%) applied the acaricide indicated by the efficiency test, and 144 (92.9%) said that they applied strategic control but incorrectly. There was improvement in some control stages. However, only 12 (7%) showed comprehension of all the stages of strategic control. It was concluded that there is a need for continuing assistance, so as to achieve effective improvement in controlling Rhipicephalus (Boophilus) microplus.

New records for Amblyomma sculptum (Ixodidae) on non-passerine birds in Brazil

Revista Brasileira de Parasitologia Veterinária/Brazilian Journal of Veterinary Parasitology (2016)

Hermes Ribeiro Luz João Luiz Horácio Faccini Gabriel Alves Landulfo Sócrates Fraga Costa Neto Kátia Maria Famadas

The aim of this paper was to provide new records of Amblyomma sculptum on two species of terricolous birds in two areas of the Cerrado (savannah- like) bioma: two specimens of Cariama cristata were captured in the state of Goiás and one specimen ofCrax fasciolata was captured in the state of Minas Gerais. One of the C. cristata was parasitized by 15 larvae, six nymphs, one male and two females whereas the C. fasciolata was parasitized by seven larvae and eight nymphs. This paper presents a new locality for occurrence of parasitism A. sculptum in C. cristata and a new host for C fasciolata.

<strong>Description of nymphal instars of <em>Ornithodoros mimon</em> Kohls, Clifford & Jones, 1969 (Acari: Argasidae)</strong>

Zootaxa (2013)

Gabriel Alves Landulfo Luisa Viana Pevidor Hermes Ribeiro Luz João Luiz Horácio Faccini Pablo Henrique Nunes

Ornithodoros mimon is an argasid tick common on Chiroptera in the Neotropical region, where it also bites humans aggressively. Here we describe for the first time all nymphal instars (N1, N2 and N3) of O. mimon based on optical and scanning electron microscopy. Although the nymphal instars of O. mimon resemble each other closely, there are characters that differentiate them: the N3 are taller that N1 and N2; the genital primordium occurs in some N2 and all N3; the spiracular plate in N1 and N2 is cone-like, but in N3 it is semicircular; and the submarginal dorsal groove is less distinct in N1 but more evident in N3. Nymphs of 0. mimon closely resemble the bat-associated species of the genus Ornithodoros included in the Alectorobius group. We review prior descriptions of nymphs of the Alectorobius group and make comparisons with nymphs of O. minon, highlighting characters with diagnostic information, such as the idiosomal shape, presence of discs and hood and absence subapical protuberance of tarsus I. The description of nymphal instars of O. mimon herein presented, improves the taxonomy of the family Argasidae, performing a work more detailed about the immature stage of this species.

Immature argasid ticks: diagnosis and keys for Neotropical region

Revista Brasileira de Parasitologia Veterinária/Brazilian Journal of Veterinary Parasitology (2013)

Darci Moraes Barros‐Battesti Diego Garcia Ramirez Gabriel Alves Landulfo João Luiz Horácio Faccini Filipe Dantas‐Torres

Many argasid tick species are known only through their larval descriptions, in which the chaetotaxy, together with other external morphological characteristics, has been used to separate genera and species. However, the illustrations of these features are based on optical microscopy alone and many of these features are not clearly defined. Because of the difficulties in determining the larval and nymph stages of some genera, we have prepared illustrated keys for the immature stages of argasids, including an up-to-date list of the known species of the Neotropical region. We have also included an illustrated key for larvae of the Ornithodoros species from Brazil, based on scanning electron microscopy.

The role of ear mites of the genus Raillietia (Acari: Raillietiidae) in otitis of domestic ruminants

Pesquisa Veterinária Brasileira (2011)

Fernando R.A. Ferry João Luiz Horácio Faccini Tetsuo Inada

This paper presents a hypothesis on the involvement of species of the genus Raillietia Trouessart in the pathology of parasitic otitis in domestic ruminants. The chelicerae and claws of the tarsi are structures that contribute significantly towards producing primary lesions. The movable digits of the chelicerae accidentally injure the epithelium that lines the ear canal, while the claws of the tarsi perforate the epithelium, allowing the mites to affix themselves while feeding. The lesions in the epithelium caused by the chelicerae and the claws favor multiplication of the bacteria that inhabit the ear canal, resulting in typical cases of otitis.
