| The mite Tetranychus mexicanus (McGregor) is considered a pest of a variety of plant species in the Americas. Although this mite apparently causes economic damage to Annonaceae, little is known about its biology. Here we studied the biology of T. mexicanus on soursop (Annona muricata), sweetsop (Annona squamosa) and araticum (Annona coriaceae). The first two species are the most important economical Annonaceae species in northeast Brazil; araticum is commonly found in the region, but not commercially explored. The mites were collected in the field from leaves of A. muricata and maintained in the laboratory for six months on detached leaves of A. muricata, A. squamosa and A. coriaceae, respectively, before observations started. Tetranychus mexicanus... |

| The passion fruit plant is a host for several different phytophagous mites, mainly those belonging to the Tarsonemidae, Tenuipalpidae and Tetranychidae families. Among the Tetranychidae species are Tetranychus mexicanus (McGregor, 1950) and Tetranychus desertorum Banks, 1900. The occurrence of Tetranychus marianae McGregor, 1950 was detected on yellow passion fruit Passiflora edulis Sims f. flavicarpa Degener plants under field and greenhouse conditions at the headquarters of Embrapa Cassava & Fruits Tropical Research in Cruz das Almas County, State of Bahia, Northeast Brazil. Prior records of T. marianae on the passion fruit crop in Brazil as well as the biological aspects of this species are unknown. The study on the biology of T. marianae on P.... |

| A total of 1,177 lice of four species were collected from 124 kelp gulls (Larus dominicanus) and 137 lice of the same four species from 60 Franklin's gulls (Larus pipixcan). The louse Saemundssonia lari (O Fabricius) (Phthiraptera: Philopteridae) was the most numerous on both gull species, with infestation rates of 4.9 on kelp gulls and 1.8 on Franklin's gulls. The second most abundant louse was Quadraceps punctatus (Burmeister), with a high infestation rate but low prevalence on kelp gulls; those parameters were much lower among lice from Franklin's gulls. The composition and community structure of the lice were similar on both host species, but not their infestation rates. In addition, the feather mite Zachvatkinia larica Mironov (Acari: Avenzoariidae)... |

| The objective of this work was to study the spatial distribution of Tenuipalpus heveae Baker in rubber tree plantations. The experimental area was located in Marinópolis, State of São Paulo, and corresponded to a total of 1,000 plants (clone RRIM 600) divided in 100 plots of ten plants each. A total of 16 samplings were conducted, approximately once every 10 days, between December 2007 and June 2008. On each date, samples were taken from two plants per plot, each sample corresponding to the top 30 cm of a branch randomly taken from the median region of the canopy of each plant. The number of T. heveae was evaluated on three leaflets randomly taken from each sample, using a 20x power pocket magnifying glass. The number of mites was evaluated in two areas of... |

| The objective of this research was to study infestation parameters and indexes of ectoparasites associated with each sex of the wild rodents Oligoryzomys flavescens (Waterhouse) andAkodon azarae (Fischer) in the Punta Lara wetlands, Argentina. A trend towards higher mean abundance (MA) and ectoparasite specific richness was observed in males of O. flavescens whereas those values were similar for both A. azarae sexes. The prevalence of the following ectoparasites was significantly higher on males (P < 0.05): Mysolaelaps microspinosus Fonseca (65.2%) and Hoplopleura travassosi Werneck (73.9%) on O. flavescens, and Ixodes loricatus Neumann (71.4%) on A. azarae. Only H. travassosi mean abundance was significantly higher on males (MA = 44.1). Since I.... |

| O presente trabalho teve como objetivo verificar o efeito do éster de sacarose no controle da infestação do ácaro Varroa destructor em abelhas africanizadas. Nos testes “in vitro”, testou-se o produto em abelhas e ácaros com cinco concentrações diluídas em água (T0: 100% de água destilada; T1: 0,5%; T2: 1%; T3: 2,0%; T4: 5% e T5: 10% de éster de sacarose). Nos testes de campo, o delineamento experimental utilizado foi inteiramente casualizado, com quatro tratamentos e sete repetições, totalizando 28 colônias, sendo sete delas como controle, sete com 0,1% de éster de sacarose, sete com 0,2% de éster de sacarose e sete colmeias com 0,5% éster de sacarose, diluídas em água. Nos testes “in vitro” com concentração de 0,5%, o éster de sacarose promoveu a... |

| Se determinó la fluctuación poblacional del ácaro Brevipalpus phoenicis mediante muestreos quincenales de hojas, de octubre de 2009 a septiembre de 2010, en una plantación de 1 ha de naranja Valencia (Citrus sinensis) en la zona citrícola del estado de Tabasco, localizada en el municipio de Huimanguillo (17°42'00" Norte, 93°28'26" Oeste). Asimismo, se aplicó el análisis de correlación de Pearson entre dicha fluctuación y los datos de temperatura y precipitación obtenidos de una estación meteorológica localizada en la misma zona de estudio. El ácaro se presentó durante los 12 meses considerados, con mayor densidad de población en octubre y noviembre de 2009 y de abril a septiembre de 2010. La población presentó un descenso bien marcado que inició en... |

| Resumo. Quanto às enfermidades apícolas descreve-se que o Brasil está em situação vantajosa comparando com outros países, por apresentar enxames rústicos que, por serem mais resistentes a doenças, dispensam a utilização de antibióticos. Entretanto, a dinâmica de populações do ácaro Varroa mostrou ser muito diferente das outras regiões afetadas pela varroose sendo os primeiros índices registrados superiores a 20% e, ainda, se têm poucos trabalhos em relação à taxa de infestação em diferentes regiões do Brasil. Desta forma, este trabalho teve como objetivo realizar um levantamento de incidência do ácaro Varroa destructor (Anderson & Trueman) em colmeias na região de Sinop, MT. As coletas foram realizadas nos meses de julho e agosto de 2011 em oito... |

| The presence of natural enemies in stored grains and the need of pest control alternatives led to the assessment of the effect of insecticides on the mite species Acarophenax lacunatus (Cross & Krantz), an egg parasite of the stored grain pest Rhyzopertha dominica (Fabr.). The insecticides bifenthrin, deltamethrin, pirimiphos-methyl and fenitrothion were tested at 0.4, 0.5, 0.8 and 10 ppm, respectively. Insecticide treated wheat grains were spread in petri dishes and infested with 25 adults of R. dominica. Seven days later, three mites were added to each dish, in four replicates. The number of adults of R. dominica, grain weight loss and instantaneous rate of increase (r i) of A. lacunatus were lower when the grain was treated with deltamethrin.... |

| The poultry industry is characterized for its constant search for productivity and profitability, which are based on flock health status. Brazilian Commercial laying hens (Gallus gallus domesticus) have been impacted significantly by mite infestations. This review aims to compile the literature on the occurrence, economic losses, biology, epidemiology and control of mite species considered important for the Brazilian laying poultry industry. The national experience was compared with practices of other countries and a scarcity of studies on this subject in Brazil was evident. The poultry industry has prioritized the use of pesticides to control infestations with little regard for the adverse effects. In this context, the integrated control programs using... |

| The aim of this work was to study the population reduction of the tomato leafminer moth, Tuta absoluta (Meyrick), by Pyemotes sp. in the laboratory. The mite became greenish when fed on caterpillars, pupae, and adults of T. absoluta. The caterpillars and adults of T. absoluta were quickly paralyzed by the mite venom. A single T. absoluta could host many Pyemotes sp, physogastric females, which were allowed to grow on the moth. Pyemotes sp. can be a new alternative for the biological control of T. absoluta. However, this possibility must be better understood before it could be recommended, because Pyemotes sp. could also cause dermatitis in the humans. |
