“…Studies conducted in vineyards in Rio Grande do Sul by Klock et al (2011) associated the abundance of phytoseiid to the presence of mite such as C. vitis while Moura et al (2013) attributed the abundance of phytoseiid not to the presence of mite, but to the lower use of acaricides.…”

“…Despite this finding, it is noteworthy that phytoseiid species are considered the main C. vitis antagonists, and the adoption of strategies that allow the conservation of these predators, such as the maintenance of natural vegetation within the vineyard and the use of selective treatment should be prioritized (DUSO et al, 2010). In the case of selectivity, Siqueira et al (2012b) found that azadirachtin, sulfur and spirodiclofen are harmless to N. californicus adults, one of the main predators of phytophagous species in grape cultures (KLOCK et al, 2011;MOURA et al, 2013. ).…”

“…Moreover, there is little information about production losses caused by C. vitis and criteria for decision making according to the economic returns of treatments with acaricides. Moura et al (2013) studied the mite fauna associated with spontaneous vegetation in vineyards in the municipalities of Caxias do Sul and Santana do Livramento, state of Rio Grande do Sul, and found that mite control is preventively carried out with the application of abamectin and / or sulfur, without monitoring, with no knowledge of the level of damage for the different species. As a result of this practice, economic losses may be occurring in many vineyards due to the absence of C. vitis control and / or unnecessary expenses by the use of acaricides without the corresponding economic return of the treatment cost.…”

-The southernmost region of the state of Rio Grande do Sul, Brazil, has emerged as one of the major poles for fine grape production (Vitis vinifera) for wine processing. In this region, grapevine rust mite (Calepitrimerus vitis) is one of the major pests for the culture; however, information is lacking about production losses caused by this species and acaricides for its control. In this paper, the acaricide effect of azadarachtin, boron + nitrogen on orange peel oil, sulfur and spirodiclofen on C. vitis on Merlot cultivar commercial grapevine was evaluated and production losses caused by the presence of the mite were estimated. The experiment was conducted during the 2012/2013 and 2013/2014 growing seasons, comparing the infestation levels of C. vitis and phytoseiid mites on plants treated with acaricides by the use of sticky traps. The acaricides evaluated caused a significant drop in the population of C. vitis, and spirodiclofen was the most effective, followed by sulfur, while boron + nitrogen and azadarachtin were the less effective. The products evaluated did not affect the phytoseiid population present in the experimental area. The grape production in parcels treated with spirodiclofen was significantly greater (7.430 ± 871kg.ha -1 ) than in the uncontrolled parcel (6.074 ± 316kg.ha -1 ). Significant differences in the total sourness, pH, sugar percentage, and total sugar content of grapes between treated parcels and control were not observed. The control of C. vitis with spirodiclofen and sulfur is effective to reduce losses on yield and will not affect the population of Phytoseiids. The control of C. vitis should be carried out at the beginning of infestation with rotation of active ingredients.

Não foram observadas diferenças significativas na acidez total, pH, percentual de açúcar e açúcar total da uva entre as parcelas tratadas e a testemunha. O controle de C. vitis com espirodiclofeno e enxofre é eficaz para reduzir perdas de produção e não prejudica a população de fitoseídeos. As pulverizações para controle de C. vitis devem ser realizadas no início da infestação e com alternância de acaricidas.

The presence of weeds in the margins of strawberry crops can enhance populations of predatory mites as a measure to support conservation biological control. The aims of this study were (i) to assess the composition of the acarofauna associated with strawberries and the accompanying herbaceous plants in an organic farming system, and (ii) to evaluate the possible relationships between phytophagous and predatory mites occurring in this system. Strawberry leaves and whole plants of weeds were sampled biweekly from August 2014 to February 2015 in Lapa (Paraná, Brazil). In total, 23 weed species belonging to 10 families were identified; 3768 mite individuals (from 15 families and 4 suborders) were recovered, 77% on strawberries and 23% on weeds. Abundance of predatory mites on weeds was greater than on strawberry cultivars. On strawberries, the most abundant family was Tetranychidae (84%) followed by Phytoseiidae (11.6%). In total, 16 predatory mite species from the Phytoseiidae family were identified, 13 of them occurring on strawberry leaflets. Typholodromalus aripo, Neoseiulus californicus and Typhlodromips mangleae were the most abundant mite species on strawberry leaves. On weeds, most individuals were predatory mites (59%), whereas phytophagous mites represented 17.2%. The most abundant family was Phytoseiidae (36.4%). On weeds, the phytoseiid mite T. aripo was the most abundant species, representing 34.7%. Besides being found on strawberry leaflets, T. aripo was associated with 15 weed species. Among the weeds, Bidens pilosa showed the highest values of the Shannon index (1.97), Margalef index (3.04), and Pielou's evenness index (0.95). This study emphasizes the importance of surrounding weeds as a shelter for beneficial mitefauna in strawberry fields, likely contributing to enhance conservation biological control.
