“…In spring, can cause leaves fall, harming flowers and bud development, while in the end of the summer, high population can bring leaves bronzing and affect the quality of fruit (SCHRUFT, 1985). According to Ferla and Botton (2008), in grapevine, P. ulmi cause bronzing with red patches on adaxial face of leaves. Differently, Mononychellus planki it's present only in associated plants, already has been found in soybean in the state of Rio Grande do Sul (GUEDES et al, 2004;ROG-GIA et al, 2008), where their populations seem be increasing in recent years (MORAES et al, 2006).…”

-Despite the importance of peach (Prunus persica (L.) Batsch) in Rio Grande do Sul, little is known about mites fluctuation population considered important to this crop. The objective of this study was to know the population diversity and fluctuation of mite species associated with Premier and Eldorado varieties in Roca Sales and Venâncio Aires counties, Rio Grande do Sul. The study was conducted from July 2008 to June 2009 when 15 plants were randomly chosen in each area. The plants were divided in quadrants and from each one a branch was chosen from which three leaves were removed: one collected in the apical region, another in the medium and the other in the basal region, totalizing 180 leaves/area. Five of the most abundant associated plants were collected monthly in enough amounts for the screening under the stereoscopic microscope during an hour. A total of 1,124 mites were found belonging to 14 families and 28 species. Tetranychus ludeni Zacher, 1913, Panonychus ulmi (Koch, 1836 and Mononychellus planki (McGregor, 1950) were the most abundant phytophagous mites, whereas Typhlodromalus aripo Deleon, 1967 and Phytoseiulus macropilis (Banks, 1904) the most common predatory mites. The period of one hour under stereoscopic microscope was enough to get a representative sample. In both places evaluated the ecologic indices were low, but little higherin Premier (H' 0.56; EqJ: 0.43) when compared to Eldorado (H' 0.53; EqJ 0.40). In Premier constant species were not observed and accessory only Brevipalpus phoenicis (Geijskes, 1939), T. ludeni and T. aripo. Higher abundance was observed in December and January and bigger amount in April. Already in Eldorado, T. ludeni and P. ulmi were constants. Greater abundance was observed in November and December, whereas grater richness in December and January. In both orchards were not found mites in buds. Tetranychus ludeni is the most abundant phytophagous mites with outbreak population in November, December and January and high predator diversity was observed on associated plants and on peach plants, indicating the existence of species mobility in peach orchard. Index terms: Acari, biological control, Panonychus ulmi, Tetranychus ludeni, Typhlodromalus aripo. FLUTUAÇÃO POPULACIONAL DE ÁCAROS NA CULTURA DO PESSEGUEIRO (Prunus persica (L.) Batsch) E EM PLANTAS ASSOCIADASRESUMO -Apesar da grande importância da cultura do pêssego [Prunus persica (L.) Batsch] no Rio Grande do Sul, pouco se conhece sobre a diversidade e a flutuação populacional de ácaros considerados importantes para esta cultura. O objetivo deste trabalho foi conhecer a flutuação populacional das espécies acarinas associadas às cultivares Premier e Eldorado nos municípios de Roca Sales e Venâncio Aires, Rio Grande do Sul. O estudo foi realizado no período de julho de 2008 a junho de 2009, quando foram amostradas 15 plantas escolhidas ao acaso numa área em cada município. As plantas foram divididas em quadrantes, e de cada quadrante foi escolhido um galho de onde foram retiradas três folhas das regiões...

“…Oligonychus yothersi was found at low density and does not present economic importance to the culture. Panonychus ulmi, present in the two cultivars studied in Bento Gonçalves, was recently reported in the culture in Brazil, with damages described by Ferla and Botton (2008). Commonly associated to Europe grapevine (Jeppson et al 1975;Schruft 1985;Bolland et al 1998), it becomes important to the culture in Rio Grande do Sul.…”

“…It interferes on the following year's flowering and fructification (Monteiro 2002). It was observed on grapevine in Rio Grande do Sul, where the leaves showed brownish, with reddish branches on adaxial face and premature leaf fall (Ferla and Botton 2008).…”

The mitefauna associated to Merlot and Chardonnay grapevine cultivars and associated plants in the municipalities of Bento Gonçalves and Candiota, Rio Grande do Sul was investigated. The study was developed between October 2006 and September 2007, where 20 grapevine plants were randomly chosen from each municipality and monthly sampled. Three leaves of each plant were taken. A total of 11,598 mites belonging to 14 families and to 52 species were found. Fifty-nine percent of the total specimens were collected in Candiota, being 93% associated to the Merlot cultivar. Higher species richness was observed on associated plants. Phytoseiidae showed the highest species richness, with ten species, and Eriophyidae showed the highest abundance, with 8,675 specimens. Calepitrimerus vitis (Nalepa, 1905) and Polyphagotarsonemus latus (Banks, 1904) were the most common phytophagous mites, while Neoseiulus californicus (McGregor, 1954) and Pronematus anconai (Baker ,1943) were the most common predators.

“…Four notable absences were Panonychus ulmi (Koch) (Tetranychidae), Calepitrimerus vitis (Nalepa) and Colomerus vitis (Pagenstecher) (Eriophyidae) and the predatory mite Neoseiulus californicus (McGregor) (Phytoseiidae). The first three species are the most abundant phytophagous mites on the leaves of grapevines in International Journal of Acarology 5 the southern region of Brazil (Soria and Dal Conte 2005;Ferla and Botton 2008;Johann et al 2009;Siqueira et al 2011;Johann and Ferla 2012) and other countries (Attiah 1967;James and Whitney 1993;James et al 1995;Duso and de Lillo 1996;Bernard et al 2005;Walton et al 2010). The latter is one of the most abundant and frequent predators associated with the main mite pest species on grapevines in the southern and southeastern regions of Brazil (Monteiro et al 2008;Johann et al 2009;Johann and Ferla 2012) and several other countries (Fraulo and Liburd 2007;Klock et al 2011).…”
