13. Sistemática morfológica e molecular de ácaros fitófagos do gênero Brevipalpus Donnadieu de importância econômica e quarentária para o Brasil / Morphological and molecular systematics of phytophagous mites of brevipalpus donnadieu genus of economic and quarantine importance to Brazil
Brevipalpus Donnadieu is the most importante genus in the Tenuipalpidae family. This genus presents about 300 species distributed around the world. Brevipalpus mites present agricultural importance because they are pests of several crops and especially due to their role as vectors of serious plant viroses. In Brazil, the main Brevipalpus species are B. phoen

14. 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

15. Diversidade de ácaros oribatídeos (Acari: Oribatida) em pomares comerciais de laranjeira (Citrus sinensis) no município de Manaus, Amazonas
Citrus plants shelter several species of mites that can be divided into phytophagous, predators and panfitophagous. The last group encompasses the oribatid mites, one of the most abundant arthropod group in the ground and litter of forests, also being found on the leaves, branches and fruits of vegetal species, feeding other arthropods, animal and vegetal de

16. 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

17. Microbial control of Brevipalpus phoenicis (Geijskes, 1939) with Hirsutella thompsonii Fisher / Controle microbiano de Brevipalpus phoenicis (Geijskes, 1939) com Hirsutella thompsonii Fisher
Avaliou-se o efeito de Hirsutella thompsonii ao ácaro da leprose dos citros (Brevipalpus phoenicis). Em laboratório, adultos foram mantidos em arenas sobre folhas de citros em placas contendo ágar-água solidificado. Foram avaliadas a patogenicidade e virulência do fungo ao ácaro, bem como sua persistência e compatibilidade com acaricidas. No campo, os

18. Ecology of Brevipalpus phoenicis (Geijskes) (Acari: Tenuipalpidae) on coffee plantations in the State of São Paulo / Ecologia do ácaro da mancha-anular (Brevipalpus phoenicis (Geijskes) (Acari: Tenuipalpidae) em cafeeiros no estado de São Paulo
The knowledge on the interactions among Brevipalpus phoenicis (Geijskes), other phytophagous or predaceous mites and coffee plants is still insufficient to establish an adequate management program for this crop, in order to minimize the problems caused by coffee ringspot virus (CoRSV), transmitted by B. phoenicis. In spite of the problem, little is known on

19. Eriophyoidea mites (prostigmata) associated with palm trees (arecaceae), with emphasis on the coconut mite, aceria guerreronis keifer host range and biogeographical aspects. / Ácaros Eriophyoidea (Prostigmata) associados a palmeiras (Arecaceae), com ênfase no ácaro do coqueiro, Aceria Guerreronis Keifer - espectro de hospedeiros e aspectos biogeográficos.
Muito pouco se conhece sobre os ácaros Eriophyoidea associados às palmeiras no Brasil e em outras partes do mundo. O ácaro do coqueiro, Aceria guerreronis Keifer (Prostigmata: Eriophyidae), representa uma das principais pragas desta cultura em diversas regiões produtoras. Informações sobre o espectro de hospedeiros, região de origem e fontes de recent

20. Biologia de Agistemus floridanus Gonzalez (Acari, Stigmaeidae)
The rubber tree (Hevea brasiliensis Muell. Arg.) (Euphorbiaceae) is attacked by various species of phytophagous mites in Brazil. Studies conducted in the State of Mato Grosso showed the presence of Agistemus floridanus Gonzalez, 1965 (Stigmaeidae) on rubber trees, associated with the mite Tenuipalpus heveae Baker, 1945. The aim of this work was to study the

21. Oviposição dos ácaros predadores Agistemus floridanus Gonzalez, Euseius concordis (Chant) e Neoseiulus anonymus (Chant & Baker) (Acari) em resposta a diferentes tipos de alimento
Phytoseiidae and Sigmaeidae are the most common predatory mites on rubber tree leaves in the State of Mato Grosso, associated with phytophagous mites of the families Eriophyidae, Tenuipalpidae and Tetranychidae. The aim of this work was to compare the effect of different kinds of food, including different species of mites commonly found on the rubber tree in

22. Ácaros (Arachnida, Acari) da seringueira (Hevea brasiliensis Muell. Arg.) no Estado do Mato Grosso, Brasil
Mites started to be considered economically important on rubber tree since the early 1990's, when they were considered responsible for damages caused to this crop and by the consequent yield reduction. The aim of this work was to determine the mites present on this crop in the State of Mato Grosso and to elaborate a key for the separation of the species foun

Ácaros fitoseídeos são eficientes predadores de ácaros pragas em algumas culturas. A precisa identificação das espécies é o passo inicial na seleção de inimigos naturais em um projeto de controle biológico. Os ácaros são geralmente identificados com base nas características morfológicas, mas aspectos biológicos e ecológicos, e mais recenteme

24. Wolbachia-induced parthenogenesis in a genus of phytophagous mites.
The vertically transmitted endosymbiotic bacterium Wolbachia modifies host reproduction in several ways in order to enhance its own spread. One such modification results in the induction of parthenogenesis, where males, which are unable to transmit Wolbachia, are not produced. Interestingly, parthenogenesis-inducing Wolbachia have only been found within hapl
