Incidência de Varroa destructor (Anderson &amp; Trueman) em Criação de Abelhas com Ferrão na Região de Sinop, Mato Grosso, Brasil
Provedor de dados: 25
Autores: Torres, Rodrigo de Nazaré Santos; Barreto, Marliton Rocha.
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 &amp; Trueman) em colmeias na região de Sinop, MT. As coletas foram realizadas nos meses de julho e agosto de 2011 em oito...

Provedor de dados: 82
Autores: González-Acuña,D; Corvalan,F; Barrientos,C; Doussang,D; Mathieu,C; Nilsson,L; Casanueva,ME; Palma,RL.
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)...

Autores: Gonçalves,José R.; Faroni,Lêda R.D'A.; Guedes,Raul N.C.; Oliveira,Carlos R.F. de.
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 &amp;amp; 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....

Biologia de Tetranychus mexicanus (McGregor) (Acari: Tetranychidae) em três espécies de Annonaceae
Provedor de dados: 82
Autores: Sousa,Josilene M de; Gondim Jr,Manoel G C; Lofego,Antônio C.
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...

Variações morfológicas intra e interpopulacionais de Euseius citrifolius Denmark &amp;amp; Muma e Euseius concordis (Chant) (Acari, Phytoseiidae)
Provedor de dados: 104
Autores: Noronha,Aloyséia Cristina da Silva; Moraes,Gilberto José de.
The determination of morphologic variability within and between populations of phytoseiid mites is important for the precise species identification. Euseius citrifolius Denmark &amp;amp; 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 populations preliminarily identified as E. citrifolius and E. concordis was done through examination of 10 adult females and 10 adult males of each population and of 2 to 10 adult females and males resulting from crosses between those populations. The plant substrate and collection site of each population were: E. citrijolius: Bauhinia sp. in Arroio do Meio, Rio Grande do Sul, Coffea arabica...

Occurrence of Pyemotes sp. on Tuta absoluta (Meyrick)
Provedor de dados: 52
Autores: Oliveira,Carlos Romero Ferreira de; Matos,Cláudia Helena Cysneiros; Hatano,Eduardo.
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.

Provedor de dados: 65
Autores: Rezende,Leandro do Carmo; Cunha,Lucas Maciel; Teixeira,Cristina Mara; Oliveira,Paulo Roberto de; Martins,Nelson Rodrigo da Silva.
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...
