Controle de Brevipalpus phoenicis (Geijskes, 1939) E Oligonychus ilicis (McGregor, 1917) (Acari: Tenuipalpidae, Tetranychidae) em cafeeiro e o impacto sobre ácaros benéficos: I - abamectin e emamectin

Abstract: RESUMOO ácaro Brevipalpus phoenicis (Geijskes, 1939) (Acari: Tenuipalpidae) é importante em cafeeiro (Coffea spp.), por ser o vetor do vírus da mancha-anular, responsável por queda de folhas e má qualidade da bebida do café, e o ácaro-vermelho, Oligonychus ilicis (McGregor, 1917) (Acari: Tetranychidae), por reduzir a área foliar de fotossíntese. Alguns ácaros da família Phytoseiidae são eficientes predadores associados aos ácaros-praga. Com este trabalho teve-se como objetivo estudar o controle dos ácaros-pra… Show more

“…The use of insecticides from the neonicotinoids group, even via soil, especially for the active ingredient Thiamethoxam, causes a major attack of the red mite, probably by altering the content of amino acids or hormones in the coffee (Matiello et al, 2016). O. ilicis can be chemically controlled by sulfur-based products, insecticides and acaricides mainly by abamectin and emamectin, which are selective for controlling phytophagous mites (Reis et al, 2004). However, this increase costs coffee farmers' and cause environmental damage and damage to the applicator's health.…”

“…The use of genetic resistance to mites would be important in the management of this pest, but so far there are few studies on the resistance of coffee plants. According to Reis et al (2004) the C. canephora var. kouillou is more attacked than cultivars of C. arabica.…”

“…A. Froehner). Production of both species worldwide is negatively affected by a number of factors, including unfavorable market forces, climate change, and a wide range of pests and diseases, such as bacteria, fungi, mites, , insects, , and nematodes. , Among the insects, Hypothenemus hampei (Ferrari) (Coleoptera: Curculionidae: Scolytinae), a bark beetle commonly known as the coffee berry borer (CBB), is the most important global threat to coffee production, although there are more localized pests, such as Antestiopsis Leston (Hemiptera: Pentatomidae), which both damage the plants and contaminate the beans with chemicals that make the finished beverage unpalatable. …”

“…A abamectina age sobre os ácaros por contato e ingestão, possuindo a capacidade de interferir no sistema nervoso dos ácaros, atuando como ativador de canais de cloro (Gallo et al, 2002). Reis et al (2004) avaliaram o efeito da abamectina (Vertimec 18 CE) em condições de campo, no controle do B. phoenicis em cafeeiro e verifi caram que o produto apresentou efi ciência acima de 80% no controle de todas as fases pós-embrionárias do B. phoenicis. Franceschi et al (2008) estudaram a efi cácia e a praticabilidade agronômica da abamectina (Abamectin Nortox) acrescida de óleo vegetal no controle do ácaro B. phoenicis na cultura do café e observaram que todas as dosagens avaliadas apresentaram percentuais de controle semelhante ao tratamento-padrão cyhexatin.…”
