1. Salicylic acid: resistance inducer to two-spotted spider mite in strawberry crop
RESUMO O morangueiro é atacado por diversas pragas que ocasionam redução na produtividade. Mecanismos que repelem ou evitam que essas pragas se estabeleçam representam uma tecnologia ambientalmente correta e sustentável, para reduzir a frequência no uso de agroquímicos. Neste contexto, objetivou-se avaliar o efeito do ácido salicílico (AS) na induç

2. Comparative toxicity of essential oil and blends of selected terpenes of Ocotea species from Pernambuco, Brazil, against Tetranychus urticae Koch
ABSTRACT Essential oils from the leaves of two species of the genus Ocotea that occur in the Atlantic Forest in the state of Pernambuco, Brazil, were analyzed using gas chromatography-mass spectrometry. The acaricidal activity of these oils as well as 11 selected components and blends were evaluated in fumigation and residual contact tests against the two-sp

3. SOIL MESO- AND MACROFAUNA IN TWO SOYBEAN CROPS AFTER SWINE WASTEWATER APPLICATION
ABSTRACT Hog raising generates a large amount of residues that is commonly discarded into the soil as fertilizer even with environmental risks. In this context, the aim of this study was to assess the application effects of different doses of swine wastewater (SW) associated with mineral fertilization on the abundance and diversity of organisms of soil meso-

4. Arachnids of medical importance in Brazil: main active compounds present in scorpion and spider venoms and tick saliva
Arachnida is the largest class among the arthropods, constituting over 60,000 described species (spiders, mites, ticks, scorpions, palpigrades, pseudoscorpions, solpugids and harvestmen). Many accidents are caused by arachnids, especially spiders and scorpions, while some diseases can be transmitted by mites and ticks. These animals are widely dispersed in u

5. Indução e redução de defesas em plantas de tomate por ácaros fitófagos: efeitos de ataques sequenciais e simultâneos / Induction and reduction of tomato plant defenses by spider mites: effects of sequential and simultaneous attacks
Neste estudo foi investigado o efeito das defesas induzidas diretas de plantas de tomate sobre parâmetros biológicos do ácaro vermelho Tetranychus evansi Baker &Pritchard (Acari: Tetranychidae) e do ácaro rajado Tetranychus urticae Koch (Acari: Tetranychidae), pelo fato desses ácaros serem pragas na cultura do tomateiro. No primeiro capítulo foram dete

8. Efficiency of Phytoseiulus longipes Evans as a control agent of Tetranychus evansi Baker & Pritchard (Acari: Phytoseiidae: Tetranychidae) on screenhouse tomatoes
The spider mite Tetranychus evansi Baker & Pritchard can cause severe damage to tomato crops. The predatory mite Phytoseiulus longipes Evans was recently reported in association with T. evansi in Uruguaiana, Rio Grande do Sul State, Brazil. The objective of the present study was to evaluate the effects of P. longipes on the population of T. evansi on tomatoe

9. Bioecological studies of Neozygites floridana (Entomophthorales: Neozygiteceae), the fungal pathogen of Tetranychus evansi (Acari: Tetranychidae) / Estudos bioecológicos de Neozygites floridana (Entomophthorales: Neozygitaceae) fungo patogênico de Tetranychus evansi (Acari: Tetranychidae)
The tomato red spider mite, Tetranychus evansi Baker and Pritchard is an important exotic pest of Solanaceae in Europe and Africa. It is suggested that this mite could have originated from South America, a region where it is not considered as an important pest. An important natural enemy of T. evansi in Brazil is the fungus Neozygites floridana Weiser and Mu

10. Taxonomic studies of Tetranychidae mites in Brazil and phylogeny and genetic structure of the two-spotted spider mite, Tetranychus urticae Koch, inferred from ribosomal and mitochondrial DNA sequences. / Estudos taxonômicos de ácaros Tetranychidae no Brasil e filogenia e estrutura genética do ácaro rajado, Tetranychus urticae Koch, inferidas a partir de sequências do DNA ribossômico e mitocondrial
A família Tetranychidae compreende um grande número de espécies estritamente fitófagas e inclui pragas importantes para a agricultura nacional e mundial. O ácaro rajado, Tetranychus urticae Koch (Prostigmata: Tetranychidae), é uma espécie de distribuição cosmopolita, polífaga e que se destaca pelos elevados prejuízos ocasionados às lavouras. No B

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
