1. In vitro activity of the essential oil from Hesperozygis myrtoides on Rhipicephalus (Boophilus) microplus and Haemonchus contortus
ABSTRACT Commercial antiparasitics have been the main tool to control parasites, but due to the resistance development, plant extracts have been widely investigated to find new molecules. The present study aimed to investigate the in vitro acaricide and anthelmintic activities of the essential oil from the aerial parts of Hesperozygis myrtoides (A.St.-Hil. e

2. Estudo do mecanismo de ação da atividade acaricida de Calea serrata (Asteraceae) em Rhipicephalus (Boophilus) microplus e da sua toxicidade em roedores
It has been demonstrated that the n-hexane extract of Calea serrata had acaricidal activity against larvae of R. microplus and R. sanguineus. Acetylcholinesterase (AChE), an enzyme that hydrolyses acetylcholine at cholinergic synapses, is a target for pesticides and its inhibition by organophosphates leads to paralysis and death of arthropods. Extensive uses

3. Caracterização da resistência para acaricidas no carrapato Boophilus microplus / Characterization of acaricide resistance in Boophilus microplus
Boophilus microplus é um ectoparasita hematófago de bovinos, presente em áreas tropicais e subtropicais no mundo. É causador de enormes perdas econômicas pela espoliação que causa ao hospedeiro, além de ser transmissor de Anaplasma sp. e Babesia spp. O principal método de controle utilizado atualmente é o controle químico, que, embora eficiente, �

4. Evaluation of activity of synthetic chemical acaricides, botanical extract on Rhipicephalus sanguineus and action of essential oils on Amblyomma cajennense. / Avaliação da atividade de acaricidas químicos sintéticos, extrato botânico sobre Rhipicephalus sanguineus e ação dos óleos essenciais sobre Amblyomma cajennens.
Amblyomma cajennense (Fabricius, 1787) (Acari, Ixodidae) known as tick-star, is a ixodid heteroxenous tree-host found too often in horses. Have little specific parasite, particularly in periods of larvae and nymph, is considered the most important in ixodid transmission of spotted fever to humans in Brazil. Rhipicephalus sanguineus, tick ectoparasite mainly

6. Resistance of Brevipalpus phoenicis (Geijskes, 1939) (Acari: Tenuipalpidae) to acaricides that inhibit cellular respiration in citrus groves / Resistência de Brevipalpus phoenicis (Geijskes, 1939) (Acari: Tenuipalpidae) a acaricidas inibidores da respiração celular na cultura dos citros
Acaricides that affect the cellular respiration process, specifically in the energy production (ATP), have been an important component in acaricide resistance management programs. Basically, these acaricides interfere in the oxidative phosphorilation or electron transportation in the mitochondria, by inhibiting or disrupting some specific process. This group

7. Integração das estratégias de controle químico e biológico para a conservação e liberação dos ácaros predadores Neoseiulus californicus (McGregor) e Phytoseiulus macropilis (Banks) (Acari: Phytoseiidae) em programas de manejo do ácaro rajado Tetranychus urticae Koch (Acari: Tetranychidae) / Integration of chemical and biological control strategies for preserving and releasing Neoseiulus californicus (McGregor) and Phytoseiulus macropilis (Banks) (Acari: Phytoseiidae) in Tetranychus urticae Koch (Acari: Tetranychidae) management programs
The exploitation of predaceous mites to manage phytophagous mites in agricultural production systems can be affected by the use of pesticides for controlling other pests and diseases. The use of pesticides that are compatible with predaceous mites or pesticide-resistant strains can promote the conservation of these natural enemies. Another strategy to be exp

8. Mixtures of acaricides in the management of Brevipalpus phoenicis (Geijskes, 1939) (Acari: Tenuipalpidae) resistance to hexythiazox / Mistura de acaricidas no manejo da resistência de Brevipalpus phoenicis (Geijskes, 1939) (Acari: Tenuipalpidae) a hexythiazox
A mistura de hexythiazox com acaricidas de ação adulticida tem sido explorada no controle de Brevipalpus phoenicis (Geijskes, 1939) em pomares de citros. Sendo assim, o presente trabalho foi realizado com o objetivo de subsidiar a recomendação de mistura de acaricidas no manejo da resistência de B. phoenicis a hexythiazox. Para esse propósito, foram re

9. Esterase profile in a pyrethroid-resistant Brazilian strain of the cattle tick Boophilus microplus (Acari, Ixodidae)
The cattle tick Boophilus microplus causes great damage in livestock and is considered one of the most important tropical ectoparasites. The traditional method of control is based on the intensive use of pesticides, however the indiscriminate use of these compounds over the years has led to the selection of resistant ticks. Hydrolases, particularly esterases

10. Resistance dynamics of Brevipalpus phoenicis (geijskes, 1939) (acari: tenuipalpidae) to the acaricide dicofol. / Dinâmica da resistência de Brevipalpus phoenicis (Geijskes, 1939) (Acari: Tenuipalpidae) ao acaricida dicofol.
O conhecimento da dinâmica da resistência de pragas a pesticidas é de fundamental importância para a implementação de estratégias de manejo da resistência. Desta forma, o principal objetivo do presente trabalho foi estudar a dinâmica da resistência de Brevipalpus phoenicis (Geijskes, 1939) ao acaricida dicofol em pomares comerciais de citros durant

11. Detecção e caracterização da resistência de Brevipalpus phoenicis (Geijskes, 1939) (Acari: Tenuipalpidae) ao acaricida propargite. / Detection and characterization of Brevipalpus phoenicis (Geijskes, 1939) (Acari: Tenuipalpidae) resistance to the acaricide propargite.
The citrus flat mite Brevipalpus phoenicis (Geijskes) is one of the most important citrus pests because it vectors the citrus leprosis virus. The acaricide propargite has been frequently used to control this mite. Therefore, the objective of this work was to collect basic information for implementing a resistance management program of B. phoenicis to proparg
