1. A new species of Neoseiulus (Acari: Mesostigmata: Phytoseiidae) with a key for the Brazilian species of the genus
Neoseiulus HUGHES, 1948 is currently one of the largest genus of Phytoseiidae Berlese. Neoseiulus demitei sp. nov., a new species of phytoseiid mite from Rio Grande do Sul State, Brazil, is illustrated and described based on specimens collected on Tibouchina sp. (Melastomataceae) plants. This new species differs from others by having most of propodossomal se

2. Seleção de ácaros da ordem Astigmata (Acari) para uso como alimento na criação de ácaros predadores fitoseídeos (Acari: Phytoseiidae) / Screening of mites of the order Astigmata (Acari) for use as food sources in the mass rearing of predaceous phytoseiid mites (Acari: Phytoseiidae)
Ácaros da família Phytoseiidae são os predadores mais utilizados para o controle biológico de ácaros-praga. Atualmente, a produção destes ácaros é realizada em um sistema tritrófico, em que o predador é multiplicado sobre plantas infestadas por suas presas. Apesar de eficiente, este método apresenta diversas dificuldades, como o alto custo de pro

3. Functional response of Phytoseiulus macropilis under different Tetranychus urticae (Acari: Phytoseiidae, Tetranychidae) population density in laboratory
We tested the functional response of the phytoseiid predator Phytoseiulus macropilis (Banks, 1904) to different population densities of Tetranychus urticae Koch, 1836 (the two-spotted spider mite - TSSM) in the laboratory. We evaluated the curve that best fits the data obtained, based on the reduced X². The predators were obtained from leaves of Oso Grande

4. Ciclo de vida de Proprioseiopsis cannaensis (Muma) (Acari: Phytoseiidae) com diferentes tipos de alimentos
Several annual and perennial crops are severely attacked by mites from the family Eriophyidae, Tenuipalpidae and Tetranychidae. A suitable alternative commonly used in several countries for the control of these pest mites involve the use of predatory mites in the family Phytoseiidae. The phytoseiid fauna in the Brazilian natural vegetation is very rich, but

5. Bioecological aspects, damage and biological control of the coffee red spider mite, Oligonychus ilicis (McGregor, 1917) (Acari: Tetranychidae) on coffee plant. / Aspectos bioecolÃgicos, dano e controle biolÃgico do Ãcaro-vermelho do cafeeiro, Oligonychus ilicis (McGregor, 1917) (Acari: Tetranychidae)em cafeeiro
The spider mite Oligonychus ilicis (McGregor) lives in the coffee plants (Coffea spp.) leaves superior surface, where spins web favoring the adherence of dust, debris and exuviae, giving to the leaves a dirt aspect. Due to its feeding behavior, leaves lose shine becoming tan. Iphiseiodes zuluagai Denmark &Muma, 1972, Amblyseius herbicolus (Chant, 1959) and E

6. Phytoseiulus longipes: an efficient control agent of Tetranychus evansi (Acari: Phytoseiidae, Tetranychidae) in tomato crops / Phytoseiulus longipes: um eficiente agente de controle de Tetranychus evansi (Acari: Phytoseiidae, Tetranychidae) na cultura do tomateiro
O tomateiro (Lycopersicon esculentum Mill.) é comumente atacado por diferentes pragas. Tetranychus evansi Baker e Pritchard é um dos principais ácaros praga do tomateiro em alguns países. No continente africano, T. evansi tem causado até 90% de perdas nos cultivos de tomateiro. Recentemente, o ácaro predador Phytoseiulus longipes Evans foi encontrado n

7. Variações morfológicas intra e interpopulacionais de Euseius citrifolius Denmark & Muma e Euseius concordis (Chant) (Acari, Phytoseiidae)
The determination of morphologic variability within and between populations of phytoseiid mites is important for the precise species identification. Euseius citrifolius Denmark & Muma, 1970 and Euseius concordis (Chant, 1959) are phytoseiids commonly found on different crops in Brazil and other South American countries. The morphologic characterization of po

8. Stable genetic transformation of a beneficial arthropod, Metaseiulus occidentalis (Acari: Phytoseiidae), by a microinjection technique.
A microinjection technique has resulted in stable transformation of the western predatory mite Metaseiulus occidentalis. Early preblastoderm eggs within gravid females were microinjected. The needle was inserted through the cuticle of gravid females into the egg, or the tissue immediately surrounding the egg. This maternal injection method resulted in relati
