| ABSTRACT The acaricidal activity of crude ethanolic extract and fractions from the leaves of Morus nigra (Moraceae) was carried out on female cattle ticks Rhipicephalus microplus, using the adult immersion test. The mortality and fertility of females exposed to different concentrations of hexane, chloroform and ethyl acetate fractions, as well as ethanolic extract of M. nigra with concentrations of 5, 10 and 25mg/ml were evaluated using three treatment groups, two control groups and triplicate tests. The study also identified the main phenolic compounds of the extract and fractions of this species by HPLC. The chloroform fraction of leaves of M. nigra (25mg/mL) showed the best results for this species, obtaining 62.6% of inhibition of oviposition, 39.3% of... |

| RESUMO A Caatinga é um bioma exclusivamente brasileiro e um dos mais diversificados do mundo, abrigando grande variedade faunística. Este estudo objetivou relatar a presença de carrapatos em tamanduás Tamandua tetradactyla (Linnaeus, 1758) atendidos no Centro de Conservação e Manejo de Fauna da Caatinga, Petrolina-PE, Brasil. De fevereiro de 2010 a fevereiro de 2016, 23 T. tetradactyla foram recebidos e inspecionados para avaliação da presença de carrapatos. A identificação foi realizada pela observação das características morfológicas e pela utilização de chaves taxonômicas. Aproximadamente 8,69% (2/23) dos animais apresentavam parasitismo por carrapatos. Os ixodídeos foram encontrados fixados nas regiões ventral e cervical, e identificados como... |

| Samples of 10 and 14 Ctenocephalides felis felis fleas were collected on dogs from Pedreira and Mogi das Cruzes municipalities, respectively, in the State of São Paulo, Brazil, for detection of Rickettsia spp. Individual fleas were submitted to Polymerase Chain Reaction targeting the 17-kDa and the 190-kDa (OmpA) genes of Rickettsiae. This later gene is specific for spotted fever group. Nine fleas from Pedreira (90%) and four fleas from Mogi das Cruzes (28%) were positive for the 17-kDa gene, and eight fleas from Pedreira (80%) and four from Mogi das Cruzes (28%) were positive for 190-kDa gene. The nucleotide sequence of the 190-kDa products of one flea from Pedreira and one flea from Mogi das Cruzes were 100% identical to each other, and when compared to... |
