Mites (Arachnida: Acari) collected on rubber trees Hevea brasiliensis (Willd. ex A.Juss.) Müll.Arg. in Santana, Amapá state, Brazil

Abstract

The purpose of this study was to elaborate a preliminary list of the mite species associated with rubber trees in the municipality of Santana, in the state of Amapá, Brazil. Two collections of rubber tree leaves were conducted on May 2 nd and June 5 th , 2010. Twenty-five plants were sampled at random. Three leaves were collected per plant, from the lower third of the crown. The samples were placed in paper bags, packed in an isothermal box chilled gel-based pulp plant (Gelo-X ® ), and transported to the Entomology Laboratory at Embrapa Amapá, in Macapá. The leaflets were examined under a stereomicroscope, and the mites found on the adaxial and abaxial surfaces of the leaves were collected with a stilet, mounted on microscope slides in Hoyer's medium, and later identified. We collected a total of 1,722 mites of 10 families: Acaridae, Cunaxidae, Eriophyidae, Iolinidae, Phytoseiidae, Stigmaeidae, Tarsonemidae, Tenuipalpidae, Tydeidae, and Winterschmidtiidae, in addition to unidentified species of the suborders Oribatida and Astigmatina. The family Phytoseiidae represented only 2.90% of specimens collected, but showed the highest species richness (5 species

Acarologia Agrícola No Estado Do Amapá: Panorama Histórico E Desafios Futuros

“…Os trabalhos pioneiros de Mineiro, Silva e Silva (2009), Deus et al (2012), Sousa et al (2013) indicaram significativa riqueza de espécies de ácaros predadores, que por sua vez, são potenciais agentes no controle biológico natural dos ácaros-praga.…”

“…1) Em trabalho sobre ácaros conduzidos em espécies frutíferas, Mineiro, Silva e Silva ( 2009 (Deus et al, 2012). Essa espécie habita principalmente a face abaxial das folhas, causando um bronzeamento das folhas pela perda de área fotossintética, seguido de queda prematura das mesmas (Moraes e Flechtmann, 2008).…”

“…Os autores verificaram que o principal ácaro-praga no seringal estudado foi T. heveae, com elevado nível populacional nas duas amostragens (Deus et al, 2012). Foi verificado ainda o ataque do fungo Hirsutella sp.…”

“…Tampouco, existem cursos de pós-graduação que ofertem a disciplina de Acarologia. Em consequência, são escassos os trabalhos envolvendo ácaros plantícolas e predadores no estado do Amapá, tendo sido realizados apenas trabalhos pontuais, de curta duração e, em grande parte, publicados na forma de resumos (Gazel Filho, Silva e Lima, 2002;Gazel Filho e Silva, 2003;Silva e Jordão, 2005;Jordão e Silva, 2006;Mineiro, Silva e Silva, 2009;Jordão, Noronha e Funi, 2011;Deus et al, 2012;Sousa et al, 2013;Demite et al, 2015).…”

Preference of red mite Tetranychus ludeni Zacher (Acari: Tetranychidae) to sweet potato genotypes

“…Mites herbivores are common pest in agriculture (Ghazy and Suzuki, 2014;Navia et al, 2009), ornamental plants (Silva et al, 2009) and forests (Pereira et al, 2012;Deus et al, 2012) infesting a wide range of plant hosts (Mendonça et al, 2011) and are among the most important pests across the world. Tetranychus ludeni Zacher (Acari: Tetranychidae) commonly found in the tropics (Zhang, 2002), occurs worldwide and infests more than 250 plant species (Gotoh et al, 2015), especially eggplant (Solanum melongena) and okra (Abelmoschus esculentus) (Reddy, 2001).…”
