“…Esses resultados são contrários aos obtidos em citros, em que houve maior preferência do ácaro pelos frutos, seguidos pelos ramos e pelas folhas (Oliveira, 1986 (Pedro Neto et al, 2010). Essa informação é importante para o controle químico do ácaro, pois o princípio ativo utilizado pode ter eficiência diferente como acaricida e ovicida (Celoto & Papa, 2010). Na Área 1, a incidência da mancha-anular, o número de ácaros nas folhas e nos ramos, e o número de ovos nos ramos não diferiram entre as parcelas tratadas com os dois acaricidas, mas foi significativamente inferior ao observado para a testemunha (Tabela 3).…”

Resumo -O objetivo deste trabalho foi avaliar a flutuação populacional do ácaro Brevipalpus phoenicis, vetor do Coffee ringspot virus (CoRSV) -agente causal da mancha-anular do cafeeiro -, bem como a sua distribuição em plantas de café e o efeito de acaricidas no seu controle em lavouras cafeeiras. O experimento foi realizado no Município de Coromandel, na região do Alto do Paranaíba, MG, durante dois anos. No segundo ano, avaliou-se o progresso da doença, e determinou-se a relação entre o crescimento populacional do ácaro e a incidência da doença. Observou-se que a mancha-anular e o ácaro ocorreram durante todo o ano, com maiores populações e incidência da doença nos meses com menores índices pluviais e temperaturas amenas. As análises de Pearson mostraram correlação negativa entre os parâmetros climáticos e a população do ácaro. Na análise da incidência da doença em diferentes épocas, verificou-se correlação positiva entre a primeira avaliação e as avaliações subsequentes. Quanto à distribuição espacial, foi observada a presença do ácaro em toda a planta; porém, as folhas são preferidas pelos adultos, enquanto os frutos são preferidos para oviposição. Os acaricidas são eficientes para manter a população do ácaro em baixos níveis, com consequente diminuição da incidência da doença.Termos para indexação: Brevipalpus phoenicis, acaricidas, análise de correlação, vetor. Temporal analysis and control of the ringspot disease and mite vector of Coffee ringspot virusAbstract -The objective of this work was to evaluate the population fluctuation of the mite Brevipalpus phoenicis, vector of the Coffee ringspot virus (CoRSV) -the causal agent of the coffee ringspot disease -, as well as its distribution in coffee plants, and the effect of acaricides in its control in coffee crops. The experiment was carried out at the municipality of Coromandel, in the region of Alto do Paranaíba, MG, Brazil, during two years. In the second year, the progress of the disease was evaluated, and the relationship between the mite population and disease incidence was determined. Ringspot disease and mites were detected throughout the year, with larger populations and disease incidence in the months with lower rainfall and mild temperatures. Pearson analyses showed negative correlation between the climatic parameters and the mite population. In the analysis of the disease incidence in different periods, a positive correlation was found among the first and subsequent evaluations. Regarding spatial distribution, mite presence was observed in the whole plant; however, leaves are preferred by the adults, whereas the fruit are preferred for oviposition. The acaricides are effective in keeping the mite population at low levels, with consequent reduction of disease incidence.

Citrus leprosis mite is an important pest to Brazilian citriculture. Due to the potential damage caused by the virus transmitted by this mite, synthetic acaricides are the main management strategy used by citrus growers to reduce the vector population. The current review aims to provide historical data on the use of acaricides to control the citrus leprosis mite and the main factors involved with the efficacy of these products. To get to know the main products that were and have been used to control the leprosis mite, we used scientific papers that studied the toxic effect caused by pesticides on these mites. From 1959 to nowadays, more than 200 papers have been published demonstrating acaricide efficacy on the leprosis mite. Although there are several acaricides registered to control the leprosis mite (abamectin, amitraz, acrinathrin, bifenthrin, fenpropathrin, etoxazole, hexythiazox, flufenoxuron, spirodiclofen, cyflumetofen, chlorfenapyr, fenbutatin oxide, propargite, fenpyroximate, pyridaben, and sulfur), their effectiveness will be determined by factors inherent to the products, application (quality of the spray water, plant coverage by sprayed acaricide, addition of adjuvants, and tank mixture), and biological factors of the pest (biotic potential, short life cycle, reproduction type, initial infestation level, reproduction type, and evolution of mite resistance). The use of synthetic acaricides is a control option that generates short-term results for the citrus grower. However, the association with other control measures will allow more satisfactory results for the pathosystem. Additionally, information on factors that interfere with the effectiveness of acaricides needs to be generated and made available to citrus growers.
