In Mexico, redberry disease in blackberry (Rubus sp.) was first observed in Tacámbaro, Michoacán, in 2011, causing losses greater than 70%. In this study, the eriophyid mite species associated with buds and berries and its association with redberry disease were identified. Based on morphology, the specimens of mites collected from the buds and fruits were identified as Acalitus orthomera (Keifer in Bull Dept Agric State Calif XL(3):93–104, 1951) (Acari: Eriophyidae). The eriophyid mite densities in the buds of fruiting laterals were moderately to highly positively correlated (ρ = 0.6–0.95) with redberry disease incidence at harvest. In the second part of this study, the effects of different management strategies on the density of A. orthomera in fruiting lateral buds and redberry disease incidence were evaluated. Two IPM and organic experimental plots were established during the 2014 and 2016 seasons. Treatments were based on sequential or alternating applications of lime sulfur, plant extracts, soybean oil, the entomopathogenic fungus Hirsutella thompsonii, and acequinocyl, abamectin, and hexythiazox. Treatments were applied either from budbreak or the start of the blooming period. Management programs based on the application of lime sulfur alone or in blocks or alternating with acequinocyl, abamectin, or neem extracts were effective in reducing A. orthomera densities in buds and the incidence of redberry disease when applied either after budbreak or at the beginning of the blooming period; some of these treatment schemes are feasible for use in organic systems. These results will contribute to optimizing the management of redberry disease in blackberry in the context of integrated pest management.

在墨西哥，2011年在米却肯州的塔卡姆波罗首次发现了黑莓（Rubus sp。）的红莓病，造成的损失超过70％。在这项研究中，确定了与芽和浆果有关的类螨螨种及其与红莓病的联系。根据形态学，从芽和果实中收集的螨虫标本被鉴定为Acalitus orthomera（Keifer in Bull Dept Agric State Calif XL（3）：93–104，1951）（Acari：Eriophyidae）。果实侧枝芽中的螨类螨密度 与收获时红莓病的发生率呈中等至高度正相关（ρ = 0.6–0.95）。在本研究的第二部分中，不同管理策略对直链曲霉密度的影响对果实侧芽和红莓病的发病率进行了评估。在2014年和2016年季节建立了两个IPM和有机实验区。处理方法是依次或交替施用石灰硫磺，植物提取物，大豆油，昆虫病原性真菌 Hirsutella thompsonii和乙酰喹啉，阿维菌素和hethythiazox。从芽期开始或开花期开始时进行处理。基于单独使用石灰硫磺或单独或与乙酰喹啉，阿维菌素或印em提取物交替使用石灰硫磺的管理计划可有效减少直立曲霉芽后或开花期初施用时，芽的密度和红莓病的发生率；其中一些处理方案可用于有机系统。这些结果将有助于在病虫害综合治理的背景下优化黑莓中的红莓疾病管理。
