Diversidade e flutuação populacional de ácaros (Acari) em amora-preta (Rubus fruticosus, Rosaceae) no estado do Rio Grande do Sul, Brasil

Abstract

ABSTRACT. Diversity and population fluctuation of mites (Acari) in blackberry (Rubus fruticosus, Rosaceae) in the state of Rio Grande do Sul, Brazil. Mites of the families Eriophyidae, Tarsonemidae and Tetranychidae are considered of economic importance in the blackberry (Rubus fruticosus, Rosaceae), raspberry and other small fruit crops. This study was conducted from November of 2001 to October of 2003 on Brazos, Caigangue and Tupy cultivars in Ilópolis municipality, state of Rio Grande do Sul, to describe the mitefauna and its population fluctuation in blackberry crops. A total of 36,094 mites belonging to 12 families was collected. Most of the mites belong to Diptilomiopidae (80.9%) and Tetranychidae (13.9%), composed predominantly of phytophagous species. Chakrabartiella sp. (Diptilomiopidae) was the most abundant species, followed by Neotetranychus asper Feres & Flechtmann, 2000 (Tetranychidae). Stigmaeidae (2.1%) and Phytoseiidae (0.4%) were the most common families of predaceous mites, and Agistemus brasiliensis Matioli, Ueckermann & Oliveira, 2002 (Stigmaeidae) and Typhlodromalus aripo DeLeon, 1967 (Phytoseiidae) the most common predaceous species.

Phytoseiid mites (Acari: Phytoseiidae) in the northern coastal region of the Rio Grande do Sul State, Brazil

“…This species has been associated to strawberry fruits, peach trees, blackberries, grapevines and weeds. [39][40][41][42][43] E. ho and E. alatus were the most abundant in the spring sample, possibly due to the feeding habitat, as noted by McMurtry & Croft, [6] who classify these species as polyphagous (pollen feeders). E. ho only appeared at the forest plantation (A3) and Morro da Borrúsia (A4), where their food is possibly more available.…”

Diversity of mites in blackberry genotypes in Pelotas, Rio Grande do Sul, Brazil

“…(Sumers, 1960) was classified as common and frequent in almost all (128,132,139,164,178, and 181) genotypes and "Tupy". Agistemus brasiliensis was reported in the Caingangue blackberry cultivar (MARCHETTI & FERLA, 2011) and cited as a potential predator of the mite vector of citrus leprosis (MATIOLI & OLIVEIRA, 2007).…”

“…were cited as the main pests in Brazil (NAVA et Trinidad et al al., 2007;ANTUNES et al, 2014). In addition, the presence of mites has already been reported in Brazil, specifically in Rio Grande do Sul State (MARCHETTI & FERLA, 2011). However, specific studies are necessary to obtain information about the predominant mite species, their potential for harm, and how they could become a threat to commercial systems for blackberry production, as it has occurred with Acalitus essigi Hassan, 1928(KEIFER et al, 1982BAKER et al, 1996;DAVIES et al, 2001a or Acalitus orthomerus (Keifer, 1951) (BAKER et al, 1996) in other countries.…”

“…Species of phytoseiids, eriophids, tarsonemids, tetranychids, and thideids were reported in association with blackberry cultivars (MARCHETTI & FERLA, 2011;MCMURTRY & SHOW, 2012). According to MCMURTRY & SHOW (2012), a low diversity of phytoseiid mites has been observed in commercial blackberry trees, and this may be related to intensive cultivation practices, such as lack of plant diversity, alternative foods, and adverse effects of spraying with pesticides.…”

Agistemus aimogastaensis sp. n. (Acari, Actinedida, Stigmaeidae), a recently discovered predator of eriophyid mites Aceria oleae and Oxycenus maxwelli, in olive orchards in Argentina

“…Recently several studies have been done on agriculturally important crop plants, such as apple, pear and citrus orchards, blackberry fruits, coconut, coffee, and fig trees, grapevines, leguminous plants, Yerba mate trees, medicinal and ornamental plants as well as vegetable crops and the stored products of these plants (Ehara 1962; Gonzalez-Rodriguez 1961; Momen 2012; Liana and Juarez 2012; Momen 2011; Al-Atawi 2011; Marchetti and Juarez 2011; Saber and Rasmy 2010; Thakur et al 2010; Roy et al 2006, 2008, 2009; Fadamiro et al 2009; Kawashima et al 2008; Jamieson et al 2008; Matioli et al 2007; Gotoh and Shida 2007; Matioli and De Oliveira 2007; De Gouvea et al 2007; El-Sawi and Momen 2006; Mineiro et al 2006; De Vis et al 2006; Bostanian et al 2006; Putatunda 2005; Yousuf and Chouhan 2004; Arbabi and Singh 2002; Abou-Awad et al 2000). …”
